FUNCTION DESCRIPTION 

Heating mode operation 

Heating mode  

On the electrical panel the main switch must be in position -1- and the commutator in position -HEATING-. 

At each request for heat from the room thermostat, the burner starts its self-test and pre-cleaning cycle at the end of 

which combustion begins.  

Approximately 5 minutes after combustion begins, the FAN thermostat automatically starts the fan unit. 

When the burner is turned off by the room thermostat, the fan assembly continues to operate to cool the heat exchanger 

and is automatically stopped by the FAN (fan thermostat) to avoid sending cold air.  

Burner shutdown can also be caused by the intervention of the automatic reset LIMIT, the burner's maximum thermostat 

(set at 70°C), if the temperature of the air leaving the warm air heater exceeds the operating limit. 

The LIMIT automatically resets the burner after the outlet air has cooled. 

Burner shutdown may also be due to the tripping of the LIMIT2 burner safety thermostat (set at 95°C) if the temperature 

of the air leaving the warm air heater exceeds the safety limit set by the relevant standard.  

Before resetting the burner, after the LIMIT2 has tripped, you must let the outlet air cool and then proceed as 

described in the 

TRI-THERMOSTAT c

hapter of this manual.

 

LIMIT2 intervention denotes a malfunction, contact an authorized service center or qualified service 

personnel. 

Stop 

By moving the switch to the -BURNER STOP- position the burner stops while the fan unit continues to operate until it is 

turned off by the FAN thermostat (at the end of the combustion chamber/tube bundle cooling phase).  

To de-energize the whole heater, move the main switch (IG) to -O-. 

Before disconnecting the power from the main switch, make sure that the warm air heater is well 

cooled down (the fan has turned off automatically), otherwise, it may reduce the life of the warm 

air heater.       

Otherwise, the life of the warm air heater may be reduced. 

OPERATION IN VENTILATION MODE BY POSITIONING 

By positioning the switch on -VENTILATION- the warm air heater will work only in ventilation mode, excluding the burner. 

Never turn off the warm air heater at the main power switch, but always by its switch, the room 

thermostat or the clock (if installed).  

  

Otherwise, the heat remains inside the heat exchanger with serious risk of deformation.
