Room thermostat (optional)
The electronic board provides an input for
an external thermostat on connector CN7,
specifically on terminals marked with the screen
printing “TERM”.
Follow the procedure below to control room
temperature with a thermostat:
• Switch off the heat stove using the main switch
at the rear of the heat stove,
• Refer to the wiring diagram to remove the
jumper between the two terminals and connect
the cables from the external thermostat. In this
way, when the pre-set temperature is reached
the heat stove display reads “ECO TERM”.
There are a variety of heat stove operation
modes according to room thermostat setting
and ambient temperature.
If flue gas temperature reaches 220°C during
stove operation (parameter which can be
modified by the technician), the flue gas is
modulated as follows:
• flue gas exhaust motor set at maximum speed;
• pellet loading gearmotor at minimum speed;
Ignition
This procedure lowers the temperature of the
flue gas. When it returns below the threshold of
220°C, the stove restores the speed of the three
motors, bringing them back to the prior setting.
In case of a power failure, when power is restored
the display indicates the fault status COOL FIRE.
Suction will increase to expel flue gas residue.
