INSTALLATION

WARNING

• To adjust properly room temperature, install the thermostat far from heat sources, airstreams or particularly cold walls (thermal bridges).
• In order to grant the electrical safety, it is mandatory to screw the chronostat body to the wall mount plate through the two screws supplied which must be mounted in the battery holder.
• Installation and electrical wirings of this appliance must be made by qualified technicians and in compliance with the current standards.
• Before wiring the appliance be sure to turn the mains power off.
• The device is designed to be installed directly on the wall using the screw anchors provided or in a standard recess (or wall) mounted junction box with two or three modules.

To install the device carry out the following steps:

Radio system set-up

• Before installing the chronostat in the desired position, it is necessary to test whether the receiving unit correctly receives its radio signals.
• The operation is carried out by activating the ‘Test’ mode in the user menu or using the shortcut pressing together the buttons ‘OK’ and ‘ ’ (with chronostat turned on).
• In ‘Test’ mode the chronostat’s display shows the text ‘TEST’ and continuously transmits ON and OFF commands to the receiver with a pause of 2 seconds between one and the next. Every time a command is trasmitted the symbol ‘ ’ flashes on the display. The ‘Test’ mode can be exited in the user menu or switching off the chonostat by pressing the ’ ’ button. In any case, the ‘Test’ mode will end automatically after approximately 17 minutes.
• The ‘Test’ mode must be used to self-learn the address code of the chonostat on the receiver, afterwards in the receiving unit the relevant relay output should continuously toggle between On and Off state, every 2 seconds. This output state in the receiver is also displayed by its led. If this happens the chronostat is correctly communicating with the receiver. When the chonostat is positioned in the desired position, make sure that it still communicates properly with the receiver.
• If the chonostat is positioned too far away from the receiver, the relay output will always remain On or Off. In this case, it is recommended that a better position is found, possibly closer to the receiver, and make sure that it isn’t in the vicinity of metal screens or reinforced concrete walls which could weaken the radio transmission.
• The signal quality can be monitored in the receiver; see the relative documentation for further information.
• Release the wall mount plate fitted under the base of the chronostat
• Fix the plate directly on the wall or onto 2 or 3 module junction boxes by means of the two holes for screws (distance between centres: 60 mm or 85mm), taking care to pass the wires through the opening
• Make the electrical connections following the connection
• Fit the chronostat onto the wall mount plate, first matching upthe teeth on the base with the holes provided on the plate and then pressing downward on the device until the plastic teeth of the plate click into place; then fix the chronostat body to the wall mount plate through the two screws supplied which must be mounted in the battery holder (Fig. 3).
• Insert the batteries in the battery compartment (O in Fig. 1); see paragraph ‘ HOW TO INSERT/REPLACE THE BATTERIES ’.

CONNECTION TO A TELEPHONE INTERFACE
The chronostat offers the option of connecting a telephone interface with continuous operation (latching relay) to terminals 8 and 9. Use of a suitable telephone interface does not require any setting to be made on the chronostat; for directions on using the telephone interface see the instruction manual provided. Via a telephone interface it is possible to turn the chronostat Off orturn it On in the Permanent Manual mode. Depending on the commands received from the telephone interface the chronostat will act according to the following operating logic:

Telephone interface contact closed:
The chronostat will switch into the ‘Permanent Manual’ mode: the symbols will be shown on the display.

Telephone interface contact open,
After (and only after) a previous closure, if no buttons have been pressed (Manual/Off): The chronostat will be switched off and the word ‘OFF‘ will be displayed along with the ‘ ‘ symbol. If the ‘Antifreeze’ function is active the ‘ ‘ symbol will be displayed.

IMPORTANT: the commands input by pressing the control buttons will always have priority over the commands received from the telephone interface.

• If you press the button on the chronostat, the device will change its status and the ‘ ’ icon will flash to indicate that the interface command has been overridden by a command input with a control button.
• The ‘ ’ icon will stop flashing if the telephone interface sends the chronostat the same command as the one made with the button or if the telephone interface is reset. In such a case the status set by means of the control button will not be changed and the chronostat will be ready to receive a new command.

IMPORTANT

• If an Off command is sent to the chronostat via the telephone interface (contact open), it is a good idea to check that the command has been executed by the chronostat by carrying out the following realignment procedure:
• Using the functions of the telephone interface, check that the contact is open, sending an Off command if necessary.
• Send a command to the telephone interface to close the contact (the chronostat will turn on).
• Using the functions of the telephone interface, check that the contact is closed.
• Send a command to the telephone interface to open the contact (the chronostat will turn off).
• During this sequence no commands should be input with the control buttons as they have priority over the interface commands.

HOW TO INSERT / REPLACE BATTERIES

• The battery charge status is constantly displayed by means of the ‘  ‘ symbol.
• The battery charge is at a maximum if all three level indicators are lit inside the symbol.
• Instead the batteries are depleted and must be replaced when the symbol appears completely empty ‘ ‘.
• The ‘ ‘ symbol flashes in case the batteries are too depleted to allow a radio transmission

To replace the batteries proceed as follows:

• Open the flap of the battery compartment (Fig. 1).
• Remove the batteries, prying them out with the aid of a tool if necessary.
• Insert the new batteries, which must be alkaline 1.5V type AA.
• Only if the chronostat does not respond correctly carry out a reset operation by inserting a pointed object through the hole provided
• DO NOT USE NEEDLES OR TOOLS THAT COULD IRREPARABLY DAMAGE THE Chronostat.
• Check that the time is set correctly; adjust the setting if necessary

GENERALITIES

This device is a battery-powered digital weekly chronostat for controlling room temperature on three levels: Comfort, Economy or Off/Antifreeze. Its main characteristic is the lack of electrical connections; indeed the ON and OFF signals are transmitted to the receiving unit by radio, making this device easy and cheap to install, especially when there is no existing electrical system available. The chronostat can be used in both heating and air conditioning systems and it features a large backlit display that shows all functional indications, the program schedule and the room temperature reading or, alternatively, the current time. It allows to set up to 7 different time schedules, each one different for each day of the week, with a minimum intervention time of 1/2 hour during the 24 hours

STARTING UP

When starting up for the fi rst time open the battery lid and insert the batteries in the battery compartment O in Fig. 1, observing the polarities indicated. The batteries must be alkaline 1.5V type AA. If necessary carry out a reset operation by inserting a pointed object through the hole provided (N in Fig. 1); DO NOT USE NEEDLES OR TOOLS THAT COULD IRREPARABLY DAMAGE THE Chronostat.

The buttons present beneath the lower flap are 3: ‘OK’: For programming the time and current day of the week

• Forward (G in Fig. 1);
• Back (L in Fig. 1);

Setting the current time and day
To set the clock of the chronostat carry out the following steps:

• Open the flap of the battery compartment.
• Keep the ‘OK’ button pressed for at least 2 seconds; the hour digits will start flashing.
• Set the hour using buttons 
• Confirm by pressing ‘OK’; the minute digits will start flashing.
• Set the minutes using buttons
• Confirm by pressing ‘OK’; the box surrounding the current day of the week will start flashing.
• Set the current day of the week using buttons (the current day is highlighted by a box surrounding the number corresponding to the day of the week, 1 Monday .. 7 Sunday )
• Confirm by pressing ‘OK’.

Setting the Heating / Cooling mode

• The chronostat leaves the factory set in the heating mode. The chronostat is factory set to heating mode. To modify the operating logic, keep the ‘ ‘ button pressed for at least 10 seconds.
• A. If the chronostat was previously set on heating, the cooling mode will be set and the ‘ ‘ (fan) symbol will flash on the display for 8 seconds.
• B. If the chronostat was previously set on cooling, the heating mode will be set and the ‘ ‘ (flame) symbol will flash on the display for 8 seconds.
• During normal operation, the heating output activation is shown by the flame icon ‘ ‘ whereas the cooling output activation is shown by the fan icon ’ ’.

Setting the Comfort and Economy temperatures

• The Comfort temperature is set by means of the ‘ ‘ knob whereas the Economy temperature is set by means of the ‘ ‘ knob

Note: In order to have a nighttime reduction, the economy temperature must normally be set on a lower value than the comfort temperature.

The chronostat will control the room temperature in the comfort or economy mode according to the schedule programmed (see paragraph ‘SCHEDULE PROGRAMMING‘).

SWITCHING OFF – ANTIFREEZE FUNCTION
To switch the chronostat On or Off press the ‘ ‘ button. When the chronostat is Off the display will show the text “OFF” and the output will be always Off. In case the antifreeze function has been configured and the chronostat is in heating mode, the display will show also the ‘’ symbol and the room temperature will be regulated according to the antifreeze value set in the relevant parameter (see paragraph ‘USER MENU SETTINGS‘).

AUTOMATIC OPERATION / 24h MANUAL / PERMANENT MANUAL OVERRIDE FUNCTION
By pressing the ‘ ‘ button, you can override the program schedule and the chronostat will control the room temperature according to the temperature set with the ‘ ‘ knob. By pressing the ‘ ‘, button repeatedly you can switch from Automatic to 24 hour Manual, from 24 hour Manual to Permanent Manual and from Permanent Manual back to Automatic. The two ‘Manual’ modes are shown on the display with the symbol ‘ 24h ‘ manual 24h and with the symbol ‘ ‘ permanent manual. ‘Manual 24h’ mode is a temporary state which lasts until midnight of the current day afterwards the chronostat returns to the ‘Automatic mode’ i.e. to follow the programmed time schedule. The ‘permanent manual’ mode remains always active until it is modified again with the button ’ ’.

TIME / TEMPERATURE INDICATION
Pressing the ‘ ‘ button at any time, the user can choose whether to display the current time or the room temperature measured. If an external sensor has been connected to the chronostat and the chronostat has been configured to show the external sensor’s reading, pressing repeatedly the ‘ ‘ button the display will cycle the time, room temperature, floor temperature visualization. The floor temperature is indicated with the ‘ ’ symbol on the display.

SAMPLING RATE
In order to optimize the battery life, the chronostat reads the room temperature and transmits the data to the receiver every 3 minutes. Therefore it is normal that the displayed temperature is not updated immediately and one need to wait up to 3 minutes to see the output switching On or Off. Alternatively pressing ‘OK’ button when in the main screen, the user can force an update. For the same reason, at the expiry of the time schedule’s half hour, there will not be an immediate switch of the output, it will be necessary to wait up to 3 minutes in the worst case to see the new output state updated.

BACKLIGHTING
The display backlight turns on whenever and button is pressed. It turns off automatically 20 seconds after the last pressing of a button.

USER MENU SETTINGS
The user menu allows the user to set some configuration parameters of the chonostat. To enter in the menu press the ‘ ‘ button, the display will show the

• ‘ P ’ icon (bottom right) and the text ‘ PrOG ‘. Pressing repeatedly the ‘ P ‘ button the following user parameters will be scrolled:
• ‘ PrOG ’ Schedule Programming
• ‘ tESt ’ Test mode activation
• ‘ AFr ’ Antifreeze Setting
• ‘ MOrE ’ Access to the advanced parameters menu
• Press the ‘OK’ button to display the value of the parameter. To modify the selected parameter use the arrow buttons
• ’. Press the ‘OK’ button again to save and exit or press ‘ ’ to exit without saving the changes.
• In any case the chonostat exits automatically after 20 seconds of no buttons activity.

‘ PrOG ‘: SCHEDULE PROGRAMMING
Normally the chonostat displays the programmed schedule for the current day. The current day of the week is displayed on the left with a box around the corresponding day’s number, 1 Monday .. 7 Sunday. The dashes line in the top of the display shows the time schedule from 0.00 to 12.00 AM with half an hour steps, while the dashes line in the bottom shows the time schedule from 12.00 to 24.00 PM. The dashes show the operating mode of the chonostat, Comfort, Economy, Off/Antifreeze for every half an hour of the day as shown in the following:

To set the program schedule proceed as described below:

• Select the parameter ‘PrOG’ and press ‘OK’: the display will show the ‘ ’ icon and the word ‘dAy’ and the boxes corresponding to day or group of days will start flashing.
• Press buttons to set the combination of days to be programmed.
• Press the ‘OK‘ button to confirm the setting; the display will show the schedule previously programmed for that day or group of days. The display will show also the time 0.00 and the dash flashing on the interval between the time 0.00 and 0.30 to indicate wich ‘halfhour’ is selected for the modification.

• Set the operating mode; to make the programming operation easier, the chronostat leaves the factory preset with 4 time slots. Press the ‘ ’ button to scroll cyclically through the four combinations of time slots preset in the factory.

The four time slots are preset as follows

‘tESt’: TEST MODE ACTIVATION
Allows to activate/deactivate the ‘Test’ mode for the self-learning of the radio address in the receiver:

• On ‘Test’ mode active
• OFF ‘Test’ mode deactive

‘AFr’: ANTIFREEZE SETTING
The Antifreeze function allows you to select a minimum temperature to be maintained when the chronostat is off, so as to protect both the room and the equipment when the room temperature falls below the set value. The device leaves the factory with the Antifreeze function set on 3°C.

To set the Antifreeze temperature, carry out the following steps:

• Select the parameter ‘AFr’ and press the ‘OK’ button.
• The display will show the previously set Antifreeze temperature.
• Press buttons to change the setting (between OFF, 0.5°C..25°C); every change will be automatically memorized.
• To exit press the ‘ OK ’ button or else wait 10 seconds without pressing any button.

‘MOrE’: Advanced parameters menu settings
The advanced parameters menu allows the installer to configure the chonostat’s working.

WARNING
The chonostat is supplied with pre-set data for optimal working. Modification of the advanced parameters must be done only by qualified personnel.

• To access the advanced parameters menu select the ‘MOrE’ parameter and keep pressed for 2 seconds the ‘OK’ button, the display will show the first advanced parameter.
• Pressing repeatedly the ‘ P ‘ button the following advanced parameters will be scrolled
• OFS’ Room temperature offset
• ‘Entc’ External NTC sensor configuration
• ‘LinF’ Floor temperature lower limit
• ‘LSUP’ Floor temperature higher limit
• ‘OPWM’ PWM regulation on the receiver’s output
• ‘EOrM’ Extends output driving mode to the other channels of the receiver
• ‘HISt’ Room temperature regulation hysteresis

The following parameters will be displayed only if the ‘ OPWM ‘ parameter has been set to ‘ YES ’.

• ‘bP’ PWM proportional band
• ‘t int’ Integral time
• ‘PCYC’ PWM cycle time
• ‘PMIn’ Minimum time PWM ON

The following parameter will be displayed only if ‘ OPWM ’

• parameter has been set to ‘ no ’.
• ‘tMIn’ Minimum output ON time

Press ‘OK’ button to display the value of the parameter then the value can be modified with arrow buttons ‘ ’ and ‘ ’. Press ‘OK’ button to confirm the modified value and save it. To exit the parameter menu press ‘ ’. In any case the parameter menu automatically exits after 20 seconds of no button activity. When an advanced parameter is modified, a special ‘test’ procedure is automatically started. During this special ‘test’ mode, the thermostat communicates to the receiver the information for the output driving mode. Therefore it is important to verify that the receiver is powered and that the self-learning has been completed successfully and verify that the receiver’s output toggles every 2 seconds following the chronostat test commands. Once verification is done, press ‘ ’ button to stop the ‘test’ mode.

OFS’: Room temperature offset
With the Offset parameter it is possible to correct the temperature reading by ±9.9 °C in order to correct any systematic reading errors due to a positioning of the chronostat in areas unsuitable for room temperature measure. The device is factory set with the Offset to 0.0°C.

‘Entc’: External NTC sensor configuration
The chronostat features an input for an optional external NTC sensor as well as an internal sensor. The sensor can be used to read the room temperature in case the chronostat must be installed in an unsuitable position for room temperature measuring. Alternatively, the external sensor can be configured for floor temperature reading, which can be useful in an underfloor heating/cooling system.

The parameter can be set with the following values:

• ‘no’: No external sensor wired.
• ‘rOOM’: External sensor wired to read room temperature.
• ‘FLOH’: External sensor wired to read floor temperature, but it can not be shown on the display.
• ‘FLOS’: External sensor wired to read floor temperature, it can be shown on the display.

‘LinF’: Floor temperature lower limit ‘LSUP’: Floor temperature upper limit
With the external floor sensor the chronostat will be able to take into account a minimum and a maximum floor temperature limit during the room temperature regulation. In these parameters it is possible to set a minimum or maximum floor temperature limit. In case the external sensor is wired and configured to read the floor temperature, the chronostat will give priority to the limits within which the floor temperature must stay when regulating the room temperature. In heating mode, it will be possible to set a lower limit under which the floor temperature must not fall in order not to feel a cold floor, while it will be possible to set an upper limit beyond which the floor temperature must not rise in order to guarantee the maximum wellness. The chronostat alerts when it is regulating to maintain the floor temperature within the limits by blinking the ‘ ’ symbol on the display. The floor temperature lower limit can be set in the 10..30 °C range, while the upper limit can be set in the 35..50 °C range. The limits can be disabled by setting them under their minimum value by pressing the ‘ ’ arrow button until the value ‘no’ appears. The device is factory set with limits disabled.

OPWM’: PWM REGULATION ON RECEIVER’S OUTPUT
Allows to choose whether the receiver output must be ON/OFF driven or PWM (PulseWidth Modulation) driven. With ON/OFF regulation (no) the receiver will ON/OFF regulate the output with customisable hysteresis on parameter ‘HYSt’, while with PWM regulation (YES) the receiver will proportional regulate the output. The proportional regulation can be adapted to the different room with several parameters: proportional band ‘bP‘, integral time ‘tint‘, PWM cycle time ‘PCYC‘, Minimum time PWM ON ‘PMIn‘.

EOrM’: EXTENDS OUTPUT DRIVING MODE TO THE OTHER CHANNELS OF THE RECEIVER
This parameter has a meaning only if the chronostat is coupled to a multi-channel receiver (DRR02M / DLP —). If this parameter is set to ‘YES’, all the receiver’s channels will be configured with ON/OFF or PWM driving mode chosen in the parameter ‘OPWM‘ and relative parameters,hysteresis ‘HYSt’, proportional band ‘bP‘, integral time‘t int‘, PWM cycle time ‘PCYC‘, Minimum time PWM ON ‘PMIn‘. In this way the chronostat can be used to configure the output driving mode not only of the learned channel but also all the other channels on the receiver. In this way the receiver hysteresis can be customized or an output can become PWM, even if the channel will later be coupled to a plain non configurable thermostat.

HYSt’: Room temperature regulation hysteresis
It represents the hysteresis width used when an ON/OFF regulation has been chosen (‘OPWM‘= no) or when the thermostat limits the floor temperature. The factory default hysteresis is 0.2°C.

bP’: PWM PROPORTIONAL BAND
The following parameter will be displayed only if ‘ OPWM’ parameter has been set to ‘ YES ’. This parameter allows to customize the proportional band in the range
1.0 ..8.0 °C.

‘t int’: integraL TIME
The following parameter will be displayed only if ‘ OPWM’ parameter has been set to ‘ YES ’. This parameter allows to customize the integral time of the proportional regulation in the range 0 ..180 minutes (5 minutes steps). When set to zero, no integral action will be done.

‘PCYC’: PWM CYCLE TIME
The following parameter will be displayed only if ‘ OPWM’ parameter has been set to ‘ YES ’. This parameter defines the duration of each PWM cycle in minutes, i.e. every how many minutes is the variable width pulse repeated

‘PMIn’: MINIMUM TIME PWM ON
The following parameter will be displayed only if ‘ OPWM’ parameter has been set to ‘ YES ’. This parameter defines the minimum PWM pulse width i.e. the minimum output switch-on time. When an electro-thermal actuator is wired to the output, this parameter must be set with the actuator’s travel time, otherwise ‘on’ pulses of a lower time respect to the travel time would generate unuseful output actions. The parameter can be set in the range 0 .. 15 minutes.

‘tMIn’: Minimum output ON time
The following parameter will be displayed only if ‘ OPWM’ parameter has been set to ‘ no ’. This parameter allows to reduce the number of ON/OFF cycles of the output. This function is useful in case the chronostat drives a pelletstove which cannot be switched On and Off for a too short time. Once the receiver’s relay is switched On according to a heating (or cooling) need of the room, it will not be switched Off until the ‘minimum On time’ is expired. The parameter can be set in 10 minutessteps in the 0..90 minutes range. The device is factory set with the ‘minimum On time’ to 0, i.e. function disabled.

CONFIGURATION DEFAULT RESET
It is possible to reset the settings of the user menu, the advanced menu and the schedule program in order to bring all the configuration parameters of the chronostat to the default factory value. To do the default reset, access the advanced menu by holding the button ‘OK’ on the ‘MOrE’ parameter, and the press together the buttons and ‘ ‘.

CONTROL OF A PELLET STOVE
The chronostat can be configured for temperature regulation by switching On and Off a pellet stove. The receiver’s output will have to be connected to the On/Off input of the pellet stove. In order to reduce the number of switching On and Off cycles of the stove,  configure the parameters:

• OPWM: PWM regulation on receiver’s output to ‘no’.
• HYSt: Room temperature regulation hysteresis to 1.0 °C
• tMIn: Minimum output ON time to 30 minutes

TEMPERATURE REGULATION

• The thermostat can drive the output on receiver, in ON/OFF or PWM mode.
• The valve’s drive in PWM mode allows proportional regulation and therefore allows to regulate the room temperature with maximum comfort and saving.
• However, different rooms require different settings to obtain precise regulation.
• The parameters responsible for regulation quality are:
  • – ‘bp‘ Proportional band
  • – ‘t int’ Integral time
• The proportional band in °C is the difference between set point and room temperature that ensures the valve is fully opened.
• The narrower the proportional band, the more reactive is the system upon changes of the room temperature.
• An excessively narrow proportional band setting can generate room temperature oscillations or system instability.
• An excessively large setting may lead to not reaching the set temperature on set-point, in the room. No integral action is done when the integral time is set to zero and the regulation is of P (Proportional) type.
• Regulation will be of P + I (Proportional + Integral) type by setting an integral time different from zero.
• The shorter the integral time the stronger is the integral action, vice-versa, a long integral time generates a mild integral action.
• A mild or missing integral action may prevent the set temperature on set-point to being reached in the room.
• An excessively strong integral action may cause the room temperature to oscillate.
• Depending on the room these parameters may require adjustment in order to obtain the best performance

TIME SCHEDULE SHARING WITH OTHER WIRELESS THERMOSTATS
In a system made by one chronostat and some more plain thermostats one in each room, it is possible to make the thermostats regulate according the time schedule programmed in the chronostat. This can be achieved using a multi-channel receiver and associating the outputs driven by the themostats to the output driven by the chronostat. In this way a chronostat and the thermostats associated with it will form a ‘zone’. For example, in a home, it would be possible to create the ‘living zone’ and the ‘bedroom zone’, with temperature regulation in each room according to different time schedules programmed on two different chronostats. See the receiver’s documentation for instruction how to associate outputs. In the receiver, associated channels will receive from the chronostat the time slot information and therefore the information of which setpoint temperature, comfort or economy, to use for the regulation. Also the off or antifreeze states are received by the associated thermostats. If the chronostat is regulating a comfort temperature, the associated thermostats will regulate according to their setpoint knob temperature, instead if the chronostat is regulating an economy temperature, the associated thermostats will regulate according to a reduction temperature which can be adjusted in the receiver. Likewise if the chronostat is off with 5°C antifreeze function, also the associated thermostats will regulate a 5°C antifreeze temperature

CLEANING PROGRAM
This program is particularly useful during cleaning when windows are open and it is pointless either to heat or air condition rooms. In such cases the output will remain Off for a two hours period. To activate the program press the ‘ ‘ button: on the display the ‘ ‘ icon will light up and in place of the clock, the time remaining until the resumption of normal operation will be displayed. The device will go back to the previous operating mode after two hours or if you press the ‘ ‘ button again.

VACATION PROGRAM
If you intend to be away for a relatively long period it is advisable to activate the Vacation Program, which will suspend the active operating mode for the desired number of hours (from 1 to 95) or days (from 1 to 99). At the end of the set number of hours or days, the chronostat will go back into the operating mode it was in prior to activation of the Vacation Program. While it is off, the Antifreeze function will still be active and the ‘ ‘ symbol will be shown on the display, along with the countdown of the time remaining until the end of the program.

Note: Access to the vacation program will NOT be enabled while the ‘ cleaning program ‘ is on.

To activate the vacation program proceed as follows:

• Press the ‘ ‘ button: the display will show the ‘ ‘ symbol and the time ‘ h 00 ‘.
• Press buttons to set the vacation time; every change will be automatically memorized.
• Up to 95 hours, the programming is indicated in hours and the display will show ‘ h XX ‘.
• Once that value is exceeded, the device will automatically switch to the mode for programming the vacation time in days and display will show ‘ d XX ‘
• It will be possible to increase or decrease the hour or day by one unit at a time, with values ranging from 0 .. 95 hours and 4 .. 99 days.
• To activate the vacation program for the set time, press the OK ’ button again or else wait 10 seconds without pressing any button
• The display will show the flashing ‘ ‘ icon and the time remaining until the end of the vacation period.
