THERMOSTAT POST VENTILATION FUNCTION

In order to prevent an overheat stress, in 

case at the end of a DHW intake the heat 

exchanger temperature is too high, a heat 

disposal function by fan ignition is activated.

This function remains active until the 

temperature values decrease and the heat 

exchanger returns to its normal temperature.
