CHRONOTHERMOSTAT (PROGRAMMABLE THERMOSTAT) OVERVIEW
CHRONOTHERMOSTAT CONFIGURATION AND ACTIVATION IN 4 EASY STEPS
Step 1. Installing the batteries
Note: Follow the instructions in this section only if the Chronothermostat display activates the symbol or if the
display is off (symbols or numbers do not appear). Otherwise go straight to Step 2 : Correct setting of time.
To install the batteries:
1. With the Chronothermostat fixed to the wall: to access the batteries remove the front by prising with a screwdriver
at points A and B, as shown in the figure.
2. Insert the two AA LR6 type 1.5 V alkaline batteries supplied with the Chronothermostat, making sure to fit them
in the right direction (as shown on the inside of the front).
3. Refit the front part of the Chronothermostat. (Make sure to centre the front on the rear part to ensure correct
insertion of the contacts)
Step 2. Correct setting of time and day
1. Press the button . The hour indication starts flashing: press the buttons to set the correct hour from
00 to 23.
2. Press the button . The minutes indication starts flashing: press the buttons to set the correct minutes
from 00 to 59.
3. Press the button .
Step 3. Setting the weekly automatic programme
After setting the time and day, the chronothermostat will carry out the preset automatic programme.
The heating programme provides for 6 daily temperature time bands, numbered 1 to 6. The bands can be set between
00:00h and 24:00h, adjusting them by increments of 10 minutes. Each temperature level can be set between 7°C
and 32.5°C, adjusting it by increments of 0.1°C. Any combination of time and temperature during the day can be
programmed, equal for every day of the week.
The preset automatic programme is as follows:
Carry out the following instructions to modify the preset automatic programme.
1. Press the button . The 6 daily time bands flash and the number 1 in a box indicates that the time band 1
can be modified.
2. Press the button . The hour and minutes indication starts flashing: press the buttons to modify the
time band start hour by increments of 10 minutes. Keep the button pressed and the hours and minutes will
change quickly.
3. Press the button . The indication of room temperature starts flashing: press the buttons to modify the
temperature level by increments of 0.1°C. Keep the button pressed and the temperature will change quickly.
4. Press the button . The 6 daily time bands flash.
5. Then press the button to display time band 2, which can be modified by repeating points 2 to 4.
6. The other time bands can be displayed by selecting bands 3, 4, 5 or 6 with the buttons , repeating
point 5.
Important! Set the programme, making sure that each band has a different start time.
Step 4. Operation mode selection
Heating automatic mode
Press the button , displaying the 6 time bands: the one in a box will be active at that moment the
chronothermostat will work according to the automatic programme. If the display does not show the box, it
means that the current time is between 00:00h and the start of time band 1.
Exclusion of set temperature level
During automatic mode, press the buttons to temporarily change the room temperature value by
increments of 0.1°C. Keep the button pressed and the temperature will change quickly. The exclusion function,
indicated on the display by flashing of the symbol , will be cancelled at the first change of time band.
Heating manual mode
To use the chronothermostat with a fixed room temperature level press the button , displaying the
symbol (the 6 time bands are not displayed). Then press the
buttons to set the room temperature
value, by increments of 0.1°C. Keep the button pressed and the temperature will change quickly. Manual
mode will be maintained until another operation mode is selected.
Turning off heating
In case of a prolonged absence from the home or simply to turn the heating off, press the button , displaying
only ambient temperature (the symbol is not displayed). Heating is turned off, and activated only if the
room temperature falls below 5°C: function for protection against freezing in the home. To reactivate heating
and return to the previously set operation mode, press the button again.
USER PARAMETER EDITING
Duration of On/Off cycle
When the room temperature tends to approach the programmed room temperature, the Chronothermostat starts
controlling, activating and deactivating heating in a cyclic way. The sum of activation and deactivation times is
constant within a cycle. If the activation time increases, that of deactivation decreases and vice versa, propor-
tionally. Cycle duration can be modified from 5 to 60 minutes, adjusting it by increments of 1 minute.
1. Press the button for 3 seconds
2. The display shows parameter P1
Press the buttons to modify the cycle duration by increments of 1 minute. Keep the button
pressed and the time will change quickly.
3. Press any other button to exit the menu.
Control of Heating/Cooling
Carry out the following instructions to use the Chronothermostat for controlling heating or cooling.
1. Press the button for 3 seconds
2. The display shows parameter P1
3. Press the button
.
4. The display shows parameter P2.

5. Press any other button to exit the menu.
Pump antiblocking function
When the function is enabled, the Chronothermostat relay is powered for 5 seconds near 12:00h every day,
if it was not activated in the previous 24 hours.
1. Press the button for 3 seconds
2. The display shows parameter P1
3. Press the button twice.
4. The display shows parameter P3.
Set to 0 using the buttons to deactivate pump antiblocking. Set to 1 using the buttons

5. Press any other button to exit the menu.
Pre-heating function
The function is active only if heating automatic mode was selected.
When set to Automatic, the function anticipates the heating system start time (not before 00:00h on the same day)
so that the room temperature set by the user is reached at the start of the programmed band. The Chronothermostat
calculates a first hypothetical Pre-activation time: if the programmed room temperature is reached sooner than the
calculated time, the Pre-heating time is decreased and vice versa. In this way a self-learning process is created to
determine the shortest necessary pre-heating time.
The Chronothermostat also offers the possibility of setting a fixed Pre-heating slope: in this case, the room tempe-
rature will be increased by 3°C an hour.
Therefore the heating automatic programme must be programmed according to the time heating is required, and
not that of starting of the heating system.
Carry out the following instructions to activate or deactivate the function.
1. Press the button for 3 seconds
2. The display shows parameter P1
3. Press the button
3 times.
4. The display shows parameter P4.
Set to 0 using the buttons to deactivate Pre-heating. Set to 1 using the buttons to activate
Automatic Pre-heating. Set to 2 using the buttons to activate Pre-preheating with a fixed slope
of 3°C an hour.
5. Press any other button to exit the menu.
During the pre-heating function the room temperature °C symbol flashes.
The pre-heating function ends when the difference between the programmed room temperature and the actual
temperature is less than 0.5 °C.
Maximum number of daily time bands
The heating programme provides for 6 daily temperature level time bands numbered 1 to 6. If necessary
they can be reduced to a minimum of 2.
1. Press the button for 3 seconds
2. The display shows parameter P1
3. Press the button 4 times.
