FORCED OPERATIONS
Normal ventilation logic (modulating and non-modulating)
will be ignored in particular 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.
