FORCED OPERATIONS

Normal ventilation logic (modulating and non-modulating) 
will be ignored in par ticular forcing situations which could be 
necessary for the correct temperature control or functioning 
of the terminal. 
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.

 - if ventilation is set on standby always ON, the 

selected speed is maintained once the temperature 
setpoint is reached.

• 

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.)

 - if ventilation is set on standby always ON, the 

selected speed is maintained once the temperature 
setpoint is reached.

VALVE

The control can manage 2- or 3-way ON/OFF (i.e. fully open 
or fully closed) or modulating valves (valve opening can 
range between 0%

 and 100%).

ON/OFF VALVE

Valve (2- or 3-way) opening is controlled depending on the 
operating setpoint and air temperature setpoint.

COOLING

HEATING

MODULATING VALVE

Valve ( 2- or 3-way) opening is controlled depending on the 
operating setpoint and air temperature setpoint. The opening 
adjustment logic follows the diagrams provided below.
