REGULATION OF SUPPLY AIR
Supplying air regulation should be activated by setting setpoint
61 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 101), and the
other for heating (variable 100), 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 62) is adjustable

BLOWING REGULATION BY AIR DAMPER
Regulation of air supplying by the air damper must be activated
by setting setpoint 66 to ON.
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 (variable 'R_Supply_Damper') 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 78) if the outside temperature
is less than the minimum outside air temperature (setpoint
76).
The power factor is recalculated periodically by the
CLIMATIC™. The integration time is adjustable (setpoint 62).
CLIMATIC™ PARAMETERS
REGULATION IN HUMIDITY
Two power factors, one for dehumidifying (variable 105), the
other for humidifying (variable 104), 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 67).
