7.1 OPERATING WITH THE ROOM TEMPERATURE THERMOSTAT (not supplied)
The contacts for the connection of the room temperature thermostat can be
accessed inside the electronic board compartment.
If installed, the thermostat will pilot the appliance as follows:
• When the room temperature reaches the set temperature (only during the
RUNNING phase) the thermostat closes the contact and the heater shifts to the
minimum room fan speed and minimum combustion power.
• When the room temperature drops below the preset value, the thermostat opens
the contact and the stove returns to the preset ventilation and combustion power
values.
In these conditions the automatic on-off settings are disabled. By using the room
temperature thermostat the heater does not shut down, therefore electrical
energy consumption is kept to the minimum and the heating element has a
longer life.
CAUTION: the room temperature thermostat must be connected to the
red wires on the electronic board. N.C. (normally closed) contacts must
be used for the connection to the additional room temperature
thermostat. (see par. 11 – ELECTRICAL WIRING)
7.2 OPERATING WITH THE ADDITIONAL CHRONOTHERMOSTAT (not supplied)
A chronothermostat can be installed as an alternative to the additional room temperature thermostat. The contacts for the
connection of the chronothermostat can be accessed inside the electronic board compartment.
Using this configuration, when the contact of the chronothermostat closes the Star startup procedure begins. When it opens the
OFF cycle begins. The operating conditions at ignition (combustion level – ventilation speed) are the same as those used before the
last non-manual shut down of the heater. With the chronothermostat the appliance can be piloted by simply adjusting the desired
room temperature value. Once the temperature is set, when the room temperature reaches this value, the chronothermostat opens
the contact to command a shut down cycle of the heater. When the room temperature drops below the set value, the
chronothermostat commands a start cycle. As well as the room temperature, with the chronothermostat you can also set the time
and date for the on-off cycles for the various days of the week. It is therefore possible to program a momentary shutting down of the
heater according to the room temperature.
CAUTION: If you select an inappropriate value for the room temperature, the heater will be subjected to continual on-
off cycles with consequent increase in electrical energy consumption and excessive wear of the heating element. The
manufacturer recommends setting a suitable room temperature value in the chronothermostat in order to prevent this
possibility.
The manufacturer denies all responsibility for the life of the electrical heater if subjected to excessive start ups. It is
recommended not to exceed three lighting cycles per day.
CAUTION: The chronothermostat must be connected to the black wires on the electronic board. N.C. (normally
closed) contacts must be used for the connection to the additional room temperature thermostat. (see par. 11 –
ELECTRICAL WIRING)
CAUTION: In the event of connections to a chronothermostat, Thermorossi S.p.A. shall not be held responsible for
the appliance not starting up, smoke leaks, breakage of the lighting components. In the event of a programmed cycle
on always ensure that the brazier is clean and seated correctly in its lodging.
When the programming is enabled, that is on cr appears momentarily on the display and the steady LED appears in
the bottom right corner of the control panel display (see para. 5.3), the additional chronothermostat is disabled.
8 - CLEANING AND MAINTENANCE
8.1 FOREWORD
Before beginning any maintenance operation ensure that the appliance is in the OFF phase and disconnect it from
the electric power outlet.
Your pellet appliance is a solid fuel generator and consequently requires frequent controls and general cleaning, in
order to guarantee that it continues to function correctly and to ensure optimal efficiency. If the heater is not used for
long periods, the flue pipe and flue outlet must be checked for obstructions before relighting. It is necessary to
accurately follow the directions given below: otherwise severe damages may occur for the product, the installation,
objects and the people who use the generator.
