TECHNICAL DATA

WARNING

• Read this manual carefully before using the product because it contains important indications regarding safety, installation and use. Keep this manual available for further consultation.
• The installation and electrical connection of the devices and appliances must be implemented by a person with electrotechnical expertise only and in conformity with current laws and regulations.
• Before starting any operations on the device, disconnect the 230V~ mains power supply
• If the display flashes the room temperature at 0 °C o +37.7 °C (+32 °F o +99.9 °F) it means that the measured temperature is over the scale limit.
• If the display flashes “- – – -” it means that the probe is not working, all thermoregulation activity is suspended.
• Use only two still alkaline 1.5V batteries type AAA (LR03); fitting inappropriate batteries could lead to loss of the entered programming.
• N.B.: this product has been tested and guarantees all its characteristics with DURACELL or ENERGIZER alkaline batteries. 230V ac model
• After installing and setting the thermostat, in case of the absence of power supply, the display switches off saving all the programmed settings affected, when power supply is reinstated, the display switches back on and the device returns to its normal functions.
• When required, wipe the thermostat with a slightly damp cloth.
• The manufacturer has the faculty to introduce all the technical and production changes which will be deemed necessary with no obligation of prior notice.

USER INSTRUCTIONS

CHANGING FUNCTION MODE

Changing from COMFORT temperature to ECONOMY temperature and vice versa
Press Mode once. The symbol and the set temperature will start flashing; press OK within 5 seconds to confirm.

Changing from NORMAL FUNCTION to OFF
Press Mode twice. The word OFF and the set antifreeze temperature will start flashing; press OK within 5 seconds to confirm.

Changing from WINTER to summer and vice versa

• PressMode 3 times.
• The symbol and the set temperature will start flashing; press
• OKwithin 5 seconds to confirm

Changing from OFF to NORMAL FUNCTION
Press Mode once to return to the previous function mode

CHANGE T set TEMPERATURE DEFAULT

• From the current mode it is possible to change the setting of the T Set temperature by directly pressing the or , key, the new setting will be instantly stored.
• Press one or more times the Mode key until the required function mode is displayed.
• press the key to increase the T Set reading or the key to reduce it.

BATTERIES’ LOW OR FLAT SIGNAL

• The flashing of the symbol indicates that the batteries are low, from this moment on there are aprox. 30 days time to replace the batteries.
• If the low batteries are not replaced within the declared time, the display will turn off leaving only a fixed symbol.
• Every heat regulation is suspended and all settings are stored to be reactivated once batteries have been replaced.

ABSENCE OF LINE POWER SUPPLY
In case of absence of power supply the thermostat display switches off completely deactivating heat regulation and saving and storing all settings effected, when the power supply resumes, the display switches on again and the device returns to its normal function.

ACCESS TO PROGRAMMING

It is preferable that programming is accessed by the installer or expert user since changing some of the default settings could compromise the correct function of the installation

In the program menu you access the various functions impulse pressing the Mode key, these being in sequence:

• Set scale of temperatures (°C or °F).
• Ad just measured room temperature (OFFSET).
• Block temperature set.
• Select temperature regulation mode:
• (DIFFERENTIAL ON/OFF or PROPORTIONAL).
• Change hysteresis set readings (Differential on/off).
• Change set time cycle (Proportional).
• Adjust or Exclude set antifreeze temperature

SETTING OF THE TEMPERATURE SCALE
The thermostat is preset in production for viewing the temperatures in Celsius degrees, it is possible however to change to the Fahrenheit scale or viceversa with the following procedure

ADJUSTMENT OF ROOM TEMPERATURE READING 
If for any reason the thermostat is installed in a position for which the measured temperature might be influenced (eg. an external wall which in the winter is on average colder that the rest of the house) it is possible to set an Offset (adjustment reading) of the measured temperature, the adjustment which can be set is from-2 °C to+2 °Cor from -3.6 to+3.6 °F.

BLOCK MAX TEMPERATURE SETTING (winter) and MIN TEMPERATURE (summer)
In particular cases of thermostat installation, eg. In public buildings, hotels etc. it could be useful to limit the temperature set to comfort in order to avoid erroneous settings by nonauthorized personnel.
It is, therefore, possible to limit the maximum temperature settings if the thermostat is in Winter mode (heating) or limit the minimum temperature setting of the thermostat is in Summer mode (cooling). In the default configuration, no block has been set.

Example: block maximum Comfort temperature Winter mode

Example: block minimum Comfort temperature for Summer mode (cooling)

• Press the or key to set the maximum temperature block reading.
• Press the OK key to save and pass on to the Cooling block setting or keep it pressed for at least 4 seconds to save the new setting and exit program menu.
• Press the or key to set the minimum temperature block reading.
• Press the OK key to save and pass on to the subsequent setting or keep pressed for at least 4 seconds to save the new setting and exit program menu.

TEMPERATURE REGULATION
The thermostat has been manufactured to work in differential mod (ON/OFF) with thermal differential reading (hysteresis) preset at 0. 5 °C(setting from0,2 °Cto 1,2°C) . The hysteresis reading must be set on the basis of the thermal inertia of the system; a low reading is advisable for systems with radiators (eg, in cast iron) and a high reading for fan coil systems

. As opposed to the differential, the temperature can be adjusted PROPORTIONALLY (PROP) setting cycles from 7 to 20 minutes (default 10 minutes) This system maintains the desired temperature more stable, whilst increasing the user’s comfort sensation and saving on energy consumption

SELECT TEMPERATURE ADJUSTMENT MODES (DIFFERENTIAL ON/OFF or PROPORTIONAL)
This procedure enables the selection of the temperature adjustment modes between the Differential ON:OFF (manufacturer’s default) and Proportional PROP.

SETTING OF THE HYSTERESIS
The hysteresis reading in the ON:OFF adjustment modemust be set on the basis of the thermal inertia of the system; a low reading is advisable for systems with radiators (eg, in cast iron) and a high reading for fan coil systems. The readings which can be set from 0,2 °C to 1,2 °C (0,3 °F to 2,1 °F); the default reading is 0,5 °C (0,9 °F).

DURATION OF THE PROPORTIONAL CYCLE
The duration of the control cycle for the PROPmode can be set from 7 to 20 minutes; a long cycle is advisable for systems with high thermal inertia (cast iron radiators, floor heating systems) and a short cycle for systems with low thermal inertia (fan coil). The default setting is 10minutes.

ADJUST OR EXCLUDE ANTIFREEZE PROTECTION
When the thermostat is OFF, it is programmed to protect the system in case of frost when the temperature goes below +4.0 °C (+39.2 °F); thus setting is adjustable from +4.0 °C to +12.0 °C (+39.2 °F÷+53.6 °F). It is possible to exclude this function. In this case the system will be exposed to eventual damage caused by frost. miss ina ka mbl ly kar ja rahi

RESET OPERATION

RESET
Resetting should be done by the installer or expert user as with this operation all the settings and programming previously defined according to the type of installationwill be lost. Once the reset operation is done, the thermostat restores all the default settings provided by the manufacturer

• Press the 4 buttons of the thermostat simultaneously for at least 4 seconds.
• All the display segments switch on for a few seconds
• The thermostat resumes its function in Heating mode (Winter) restoring all the default settings provided by the manufacturer.
