lation, use and maintenance guide
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 indicated in Figure 1. 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 and minimum combustion power. This condition is indicated on the display by the
blinking ventilation bar and combustion bar: the appliance ignores all commands transmitted to it. By using the room temperature
thermostat the appliance does not shut down, therefore electrical energy consumption is kept to the minimum and the appliance
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.
CAUTION: Use 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.
7.2 OPERATING WITH THE ADDITIONAL CHRONOTHERMOSTAT (not supplied)
As an alternative to the room temperature thermostat, a chonothermostat can be installed by connecting it to the board as indicated
in Figure 1. Using this output 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.
CAUTION: 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.
At the end of the preset time the contact will open and perform the appliance shut down process. Similarly at the preset startup time
the contact will close and initiate the START cycle. The chronothermostat can be used to program start up and shut down times and
dates for the appliance. It is therefore possible to program a momentary shut down of the appliance according to the preset time.
Do not shut down the appliance according to the room temperature.
It is mandatory to deactivate the “Crono” symbol on the display (see para. 5.3) if an external chronothermostat is used.
CAUTION: The manufacturer denies all responsibility for the life of the electrical heater if subjected to excessive start ups.
It is recommended not to set the desired room temperature or to set it at the highest possible value for the
chronothermostat in order to avert this danger.
CAUTION: Use N.O. (normally open) contacts for the connection to the chronothermostat.
CAUTION: In the event of connections to the chronothermostat Thermorossi shall not be held responsible for the
appliance not starting up, smoke leaks, breakage of the lighting component. In the event of a programmed cycle on always
ensure that the brazier is clean and seated correctly in its lodging. A maximum of 3 on-off cycles per day are permitted.
The chronothermostat must have a thermal hysteresis that is not less than 2°C.
8 - CLEANING AND MAINTENANCE
8.1 FOREWORD
Before commencing any operation disconnect the appliance from the electric power outlet. Your pellet appliance needs
maintenance; it requires a few simple, basic but frequent control and general cleaning operations. This will guarantee safe
and regular operation and optimal output at all times. If the product is unused for a prolonged period of time it is mandatory
to inspect the smoke channel and outlet to ensure that there are no obstructions before use. 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. Failure to observe cleaning and maintenance instructions will immediately void the warranty
. Warning: do not wet the appliance and do not touch the electrical parts with wet hands. Never vacuum hot ash: this could
damage the vacuum device. All the cleaning operations described in this manual must be carried out when the appliance
is cold.
