7 ADDITIONAL ROOM TEMPERATURE THERMOSTAT / ADDITIONAL CHRONOTHERMOSTAT
Your appliance is already fitted with all the temperature adjustment and programming functions. However, it is possible to connect the appliance
to a room temperature thermostat or an additional chronothermostat:
---> for an additional room temperature thermostat connect terminals 7-8 directly to terminal bock CN7 on the board as illustrated in the figure
below.
---> for an additional chronothermostat
– modem connect terminals 9-10 directly to terminal bock CN7 on the board as illustrated in
the figure below.

Contacts 7/8 of the terminal block CN7
This operation must be exclusively performed by qualified professional staff, as set forth by Decree no. 37 of 22nd
January 2008 and applicable laws on the subject. Before performing said task, make sure the power supply cable is
disconnected from the electrical power socket.
The contacts are defined as "FREE" contacts and they must never be supplied with voltage. It is strictly prohibited to
supply any tension whatsoever to the above-mentioned terminals as this would permanently damage the control board;
such damage is not covered by WARRANTY
.
7.1 OPERATING WITH THE ADDITIONAL ROOM TEMPERATURE THERMOSTAT (not supplied)
An additional room temperature thermostat can be installed by connecting it to the board as shown in the figure.
The operating
principle is as follows:
When the room temperature reaches the set temperature (only during the WORK phase) the thermostat closes the contact and the
appliance shifts to the minimum room fan speed (if activated) and minimum combustion power. This condition is shown on the display
with the flashing of the bar indicating ventilation (if activated) and the bar indicating combustion: the appliance overrides all prompted
commands. By using the room temperature thermostat the appliance does not shut down, therefore electrical energy consumption is
kept to the minimum and the heater has a longer life. When the room temperature drops the thermostat opens the contact and the
appliance returns to its original position in terms of thermal power and ventilation. In this position the appliance can be started up
automatically via the programming.
ATTENTION:
Use common type N.O. (normally open) contacts for the connection to the additional room temperature
thermostat. The thermostat must have a thermal hysteresis that is not less than 2°C.
If you use the Room Control device you cannot use the additional room temperature thermostat
.
7.2 OPERATING WITH THE ADDITIONAL CHRONOTHERMOSTAT (not supplied)
As an alternative to the room temperature thermostat, a chronothermostat can be installed by connecting it to the board as shown in
the figure. This function is particularly suitable for people with impaired vision. Using this input, when the chronothermostat contact
closes, the START cycle begins, whereas when the contact opens the OFF cycle begins. The operating level at start up (combustion
power - fan speed) is the same as the level used before the last time the appliance shut down.
ATTENTION: when using the chronothermostat program up to a maximum of 3 on-off cycles without setting the desired
target temperature or set it at the highest possible value for the chronothermostat.
