Possible situations:
in COOLING MODE:
- with on-board controller and configurations with
valve: the minimum available speed is maintained
even when the temperature is reached
- with on-board controller and configurations without
valve: every 10 minutes a 2-minute washing at
medium speed with the fan stopped allows the air
probe to perform a more precise room temperature
reading.
in HEATING MODE:
- with the heater on: ventilation is forced at medium
speed
- once the heater is switched off: post-ventilation is
maintained at medium speed for 2 minutes. (NB:
this ventilation will be completed even should the
thermostat be turned off or pass to the cooling
mode.)
VALVE
The control can manage 2- or 3-way ON/OFF (i.e. fully open
or fully closed) or modulating valves (valve opening can

Water temperature control for opening consent only
concerns configurations with 3-way valves and electrical
heater. In such configurations the water temperature will be
checked in the following cases:
Heating with heater: heater operation requires forced
