REGULATION OF SUPPLY AIR
Supplying air regulation should be activated by setting setpoint
58 to ON.
The main aim of supplying air regulation is to maintain the
temperature of supplied air at a value close to the average of
the neutral zone, if ambient air regulation is not active.
Two power factors, one for cooling (variable 75), and the other
for heating (variable 76), are calculated according to the
difference in temperature between the setpoint and the
reference temperature.
The power factors are periodically recalculated by the
CLIMATIC™. The integration time (setpoint 59) is adjustable

CLIMATIC™ PARAMETERS
BLOWING REGULATION BY AIR DAMPER
The aim of air supplying regulation by the air damper is to
even out the temperature of supplied air to a value close to
the average of the neutral zone.
This function is not taken into account if blowing regulation is
active.
A power factor is calculated according to difference in
temperature between the setpoint and the ambient and outside
temperatures.
The progression of the power factor is limited by the maximum
percentage of fresh air (setpoint 72) if the outside temperature
is less than the minimum outside air temperature (setpoint
71).
REGULATION IN HUMIDITY
Two power factors, one for dehumidifying (variable 79), the
other for humidifying (variable 80), are calculated according
to the difference in relative hygrometry between the setpoint
and the reference relative hygrometry.
The power factors are recalculated periodically by the
CLIMATIC™. The integration time is adjustable (setpoint 63).
