• Confirm by pressing ‘OK’; the output of the time and day setting is automatic.

Time/Temperature/Humidity Display
By repeatedly pressing the ‘‘ the display can alternately show the actual time, the room temperature (in °C) read by the internal sensor, distinguished by the ‘ ‘ icon, the room temperature (in °C) read by the remote probe (if connected) distinguished by the ‘ ‘ icon and the room humidity (in %RH) read by the internal sensor, distinguished by the ‘ ‘ icon. The temperature and humidity readings are displayed corrected by the Offset value set.

ATTENTION: In order to optimise battery duration, the programmable thermo-hygrostat performs sensor readings and error controls every 3 minutes or when ‘Ok’ is pressed and consequently, decides on activation or deactivation of the relay. Any error message must disappear within 3 minutes or on pressing the ‘Ok’ key. If the message does not disappear then problems have been detected on the sensors.

Note:
If the ‘ rEG ’ parameter is set at ‘ In ‘, but an error is detected on the internal sensor, the display will show ‘ SEnS E xx ’. In this situation the adjustment will be automatically interrupted and both relays will be placed in the Normally Open position. If the ‘ rEG ’ parameter has been set at ‘ Out ‘ but the remote probe has not been connected or is damaged, the display will show the respective wording ‘ SEnS OPEN ‘ or ‘ SEnS SHrt ‘ with the ‘ ‘ icon on.

Comfort and Economy temperatures/humidity adjustment
During normal operation, the display shows the room temperature and humidity reading and the icon relative to the current setting mode or. The programmable thermo-hygrostat reads the room temperature from the internal or external sensor (depending on the setting made in the ‘ rEG ’ parameter), while the humidity is only read on the internal sensor. The flashing ‘ ‘ icon indicates that the adjustment (temperature or humidity) takes place on an internal sensor, while the flashing ‘‘ icon indicates that the adjustment (temperature only) takes place on the remote probe. Activation of the relay that controls the room humidity management system is indicated on the display by switch-on of the ‘ ‘ icon. The activation of the relay that controls the room heating/cooling management system is indicated on the display by the switch-on of the ‘ ’ icon for heating and the ‘ ’ icon for cooling.

Proceed as follows to adjust:

Note: Normally, in order to have night -time adjustment, the economy temperature/humidity must have a value lower than the comfort value.

The programmable thermo-hygrostat will adjust the room temperature in comfort or economy mode in agreement with the hourly program set (see ‘ USER PARAMETER SETTING ‘ paragraph).

Dew point control
The dew point (managed in the user parameter ‘ C-dP ’), represents the temperature below which condensate forms on the surfaces and depends on the temperature and humidity present in the room.

ATTENTION

• The dew point control is only active if the ‘ C-dp ’ (Dew Point control) parameter has been activated.
• The dew point control is only managed in cooling and/or dehumidification mode.
• If the conditions listed above are true, on the basis of the dew point, the cooler and dehumidifier command will have priority with respect to normal adjustment (i.e. with dew point control disabled).

The table blow (table 1) shows the dew point value (expressed in °C), depending on the room temperature and relative humidity, expressed as ‘ %RH ’.

Table 1

ATTENTION

• Condensate will form on the surfaces with temperature lower than or equal to that of the dew point calculated C-dP.
• The dew point is calculated automatically by the equipment when environmental conditions change.

For all details see ‘ ‘ C-dP ’ DEW POINT MANAGEMENT ‘.

Safety Control Algorithm

• The ‘ Safety Control ‘ algorithm is used to manage the two relays controlling the thermostat and the programmable thermo-hygrostat.
• The algorithm allows not to activate the two relays simultaneously, so as not to burden the electric line in the start-up phase (peak) of the temperature and humidity control systems.
• Practically, the activation is manages in a way not to have overlapping on activation of the two commands.

WARNING
When the regulation modes ‘d-EF’, ‘d-EC’ o ‘d-FP‘ are shown, the calculated dew-point (dP) value will be alternately shown.

Dew point control limitations

• When the dew point control is active in modes ‘d-EF‘ or ‘d-EC‘, the parameter ‘rEG‘ (room temperature regulation sensor) will be automatically set to the internal sensor. The dew point temperature will be calculated according to the temperature measured by the internal sensor, meanwhile, the ceiling or floor temperatures will be calculated based on the remote sensor.
• When the dew point regulation is active in mode ‘d-FP‘ the regulation sensor will be the internal one, meanwhile, the external sensor will only be used for the measured temperature.
• The dew-point temperature will always be calculated according to the temperature measured by the internal sensor. Once the parameter ‘rEG‘ is reached, the label ‘indP‘ will be shown on the display, together with the ‘SET%RH‘ icon flashing. If the regulation sensor has to be modified, the settings for the dew-point control must first be modified
• The dew-point regulation is active only when the regulator is set on cooling and dehumidification. Otherwise access to parameter ‘C-dP‘ will not be allowed and the label ‘nOdP‘ will be shown instead.
• The dew-point measurement is taken on a regular basis, according to the value set in the parameter ‘cndP‘, from 3 minutes up to a maximum of 27 minutes.
• When the dew-point regulation is activated either when restarting from the states OFF, housekeeping or vacations, or when parameters ‘d-EF‘, ‘d-EC‘ or ‘d-FP‘ have been changed; in this case the regulator will restart for 1 minute with all relays in NC position, in order to avoid sudden activations. After this phase, the normal regulation will be activated.

For further details regarding the parameters involved in the control of the dew point, see the following paragraphs.

d-EF’ Dew point control with an external probe on underfloor plants.
When the dew point regulation is active with the ‘C-dP’ parameter set on ‘d-EF’, the regulator will control both systems attached for the cooling and de-humidification according to the comparison between the dew-point temperature and the temperature measured by the external sensor, thus applying the settings of the regulation ‘d-EF’ regulation.

The following graphics describe the dew point control mode.

Where:

• dP: dew point (see table 1).
• TE: External temperature measured
• SMF: dew point increase set in the sub-parameter ‘ d-EF ‘.
• HYdP: dew point hysteresis equal to 0.5°C (cannot be modified).
• ‘d-EC’ Dew point control with an external probe on metal ceiling.

When the dew point regulation is active with the ‘C-dP’ parameter set on ‘d-EC’, the regulator will control both systems attached for the cooling and de-humidification according to the comparison between the dew-point temperature and the temperature measured by the external sensor, thus applying the settings of the regulation ‘d-EC’ regulation.

The following graphics describe the dew point control mode

Dove:

• dP: dew point (see table 1).
• TE: External temperature measured
• SMC: incremento del punto di rugiada impostato nel sottoparametro ‘ d-EC ‘.
• HYdP: dew point hysteresis equal to 0.5°C (cannot be modified). ‘d-FP’ dew point control on fixed points

If the dew point control function, ‘ C-dP ’, is activated on ‘ d-FP ’, the programmable thermo-hygrostat controls the cooling and dehumidification devices on the basis of the comparison of the temperature value of the dew point calculated and the temperature values relative to the dew points set in the sub-parameters ‘ TF1 ’ and ‘ TF2 ’.

The following graphics describe the dew point control mode

Dove:

• dP: dew point (see table 1).
• TF1: second lower threshold of the dew point (expressed in °C).
• TF2: first lower threshold of the dew point (expressed in °C).
• HYdP: dew point hysteresis equal to 0.5°C (cannot be modified).

On identification of the dew point temperature (table 1) which is to be respected, thresholds ‘ TF1 ’ and ‘ TF2 ’ will be set in order to obtain system adjustment such to prevent the formation of condensate.

Example:
dP > TF1 = the dehumidification system starts to operate, maintaining the cooling system active if it has already been activated.

The following situation then occurs:
dP > TF2 = The dehumidification system remains active, but the cooling system is deactivated.

Once the value of ‘ TF2 ’ is set lower than the minimum temperature of the cooling surface, this control allows to prevent the formation of condensate on the surface for any temperature and relative humidity value of the air.

ATTENTION

• The maximum value of ‘ TF1 ’ will be self-limited to ‘ TF2 ’ less 0.2°C.
• The ‘ TF2 ’ value must always be set with a value lower than the minimum temperature reached by the cooling surface to control or however than the coolest surface present in the room.
• The difference between the value of ‘ TF2 ’ and the minimum temperature of the coldest surface in the room will be assessed by qualified staff, according to the type of plant, thermal inertia and the various environmental conditions.

Generally, a minimum of 1°C is recommended for underfloor plants and 3°C for metal ceilings. ‘CndP’ Rate of check for the dew-point regulation
This parameter allows setting the minimum time, in minutes, which must elapse between two consecutive activations of the output relays, caused by the ‘ c-dP ‘ function intervention.
This time interval can be set in steps of 3 minutes; itwill be reinitialized every time the dew-point regulation mode is changed by the user (‘ d-EF ’, ‘ d-EC ’ or ‘ d-FP ‘).

‘Cntr’ THERMOSTAT RELAY ACTIVATION TIMER
Using this parameter it is possible to display the thermostat relay activation time meter relative to the actual day. The timer is automatically reset at midnight.

Proceed as follows:

• Select the ‘ Cntr ’ parameter and press ‘ OK ’, the device displays the hours of activation of the thermostat relay alternating with the wording ‘ Cntr ’ + the ‘ ‘ icon.
• To go back to the list of user parameters, press ‘ OK ’ and then the ‘‘ key.
• To exit the user parameters setting and restore normal operation, press ‘‘ or do not press any key for 10 seconds.

‘dFLt’ SET DEFAULT DATA
With this parameter, it is possible to reset user parameters in order to bring back all the parameters to the factory defaults.

Proceed as follows:

• Select the parameter ’dFLt’ and press ’OK’; the device automatically sets the default data and the display will show ’-dF-’ and the ‘ ‘ icon flashes.
• To return to the list of user parameters, press the ‘OK’ button.
• To exit the user parameter settings and resume normal operation, press the ‘ ‘ button or wait 10 seconds without pressing any key.

WARNING!
Restoring the Default Data will reset all settings made by the user, such as Time Program, Heating/Cooling, Set-Points, and all other programmable data.

SWITCHING OFF – ANTIFREEZE FUNCTION

• To deactivate the programmable thermo-hygrostat press the ‘ ‘ button. The display will show the word ‘ OFF ’.
• If the programmable thermo-hygrostat has been set in the heating mode, the Antifreeze function will be active and the ‘ ‘ symbol will appear on the display; in such a case the room temperature will be controlled based on the value set for the Antifreeze temperature (see paragraph ‘SETTING THE USER PARAMETERS‘).

AUTOMATIC OPERATION / 24H MANUAL / PERMANENT MANUAL OVERRIDE FUNCTION

With the ‘ ‘ key, the programmable thermo-hygrostat may be forced to adjust the room temperature and humidity according to the comfort temperature and humidity set, regardless of the time programming settings. 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. During operation in manual mode, the display does not show the time program, but only the room temperature, the status of the relays (any switch-on of the ‘ ‘ or ‘ ‘ or ‘ ‘ symbols), the ‘ 24h ‘ symbol (manual 24h) or ‘ ‘ (permanent manual) and the ‘ ‘ symbol. Pressing the ‘ ‘ button once will activate the 24-hour Manual mode and the programmable thermo-hygrostat will remain in this mode until the time 23:59 is reached, after which it will go back into the Automatic mode.

Note: If the device is set in the 24h Manual mode and the Vacation program is activated, after the Vacation period has elapsed, if it is past the time 23.59, the programmable thermo-hygrostat will go back into the Automatic mode and follow the set program schedule. Pressing the ‘ ‘ button a second time will switch the programmable thermo-hygrostat into the Permanent Manual mode and it will remain in this mode until you press the ‘ ‘ button again.

TIME/TEMPERATURE/HUMIDITY DISPLAY
By repeatedly pressing the ‘ ‘ button, the display can show the actual time with the icon relative to the temperature adjustment probe (internal ‘ ‘ or external ‘ ‘), the room temperature read by the internal sensor, distinguished by the ‘ ‘ icon, the room temperature read by the remote probe (if connected) distinguished by the ‘ ‘ icon and the room humidity read by the internal sensor, distinguished by the ‘ ‘ icon. The temperature and humidity readings are displayed and corrected by the Offset value set.

Note: If the ‘ rEG ’ parameter is set at ‘ In ’, but an error is detected on the internal sensor, the display will show ‘ SEnS E xx ’. In this situation, the adjustment will be automatically interrupted and both relays will be placed in the Normally Open position. If the ‘ rEG ’ parameter has been set at ‘ Out ‘ but the remote probe has not been connected or is damaged, the display will show the respective wording ‘ SEnS OPEN ‘ or ‘ SEnS SHrt ‘ with the ‘ ‘ icon on.

ATTENTION:

• In order to optimize battery duration, the programmable Thermo hygrostat reads the room temperature every 3 minutes and, consequently, decides on the activation or deactivation of the relays.
• Press the ‘ OK ’ button briefly to perform an instant refresh.

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

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. If the ‘ ‘ symbol (completely empty) flashes, it means that the batteries are depleted and must be replaced. In this case, both the relays are placed in the safety position(N.C.) and the display alternately shows the time (or temperature or humidity) and the word ‘ BATT ’. If the batteries are not replaced as soon as possible, the ‘ ‘ or ‘ ‘ symbols will also flash indicating that the device is blocked.
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.
• Check for the correct time and date and eventually reset it.

CONNECTION TO A TELEPHONE INTERFACE

• The programmable thermostat allows connecting a telephone interface with the continuous operation (latching relay) to the connector ‘ B ‘ in Fig. 6.
• The use of a suitable telephone interface does not require any setting to be made on the programmable thermo-hygrostat; for directions on using the telephone interface see the instruction manual provided.
• Via a telephone interface, it is possible to turn the programmable thermo-hygrostat Off or turn it On in the Permanent Manual mode. Depending on the commands received from the telephone interface the programmable thermo-hygrostat will act according to the following operating logic:
  • Telephone interface contact closed: The programmable thermo-hygrostat will switch into the ‘Permanent Manual’ mode: the ‘ ‘ and ‘ ‘ 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 programmable thermo-hygrostat 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 ‘
• ‘ or ‘ ‘ button on the programmable Thermo hygrostat, 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 programmable thermo-hygrostat 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 programmable thermo-hygrostat will be ready to receive a new command.

IMPORTANT
If an Off command is sent to the programmable Thermo hygrostat via the telephone interface (contact open), it is a good idea to check that the command has been executed by the programmable thermo-hygrostat 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 programmable thermo-hygrostat 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 programmable thermo-hygrostat will turn off).
• During this sequence, no commands should be input with the control buttons as they have priority over the interface commands.
