Recirculation air heati ng

1) The unit is ON (medium or maximum performance level)

3) The room thermostat is ON - a request for heating from the CP 08 RD controller

4) Temperature behind the heater is lower than the maximum temperature set on the control module board

Heating itself starts depending on a heating source installed (a boiler, an auxiliary pump etc. are turned on).
