will be maintained at low speed (LS).
Advantage: system very quiet, less electricity consumed, less
boiler kWs consumed.
Drawback: achieving the temperature setpoint will be very slow.
In SUMMER mode, the threshold is set by default to 100% in
order to use only LS and thereby ensure that the flow of air
blown across the heat exchange coil does not cause condensate
droplets to form

The lower the threshold (near to 0%), the longer ventilation will
be maintained at high speed (HS).
Advantage: swift building warm-up times.
Drawback: the system is similar to an On/Off control, "energy-
wasting" system.

Cut-off on setpoint :
Used to shut off the fans or
keep them on when the
setpoint is reached.
Unit -
There are two operating modes:
- YES : the ventilation is turned off when the setpoint is reached.
- NO : the ventilation will remain on (limits stratification in
WINTER mode, circulates air in SUMMER mode).

Return air/Fresh air or mix :
Used to run the system with
fresh air or return air
Unit -
Allows two operating modes when parameter 01 is not set to
tiME (in which case the operating mode will be depend on the
time schedule):
- Air.in: 100% return air.
- Air.out: fresh air or mix (depends on mechanical setting of
damper actuator supplied with the optional fresh air kit).

When fresh air or mixed air is used, the optional fresh air kit

When this time elapses, the automatic speed control (based on
the ambient temperature/temperature setpoint and the clock)
