Con guration 1 (AdC =1) - DiP 4 has no e ect
The typical application is the control of a classic system with air-
conditioner + boiler and humidity control using a CAREL proportional
humidi er, for example the compactSteam series. Dehumidi cation is
performed using the air-conditioner, making sure that the temperature
conditions are within the comfort limits.
There are two humidity set points, one for humidi cation and the other for
dehumidi cation; the changeover points for automatic humidi cation/
dehumidi cation operation are also de ned.
There is just one temperature set point for both cooling and heating, the
changeover (cooling/heating) occurs based on the activation points of
the two outputs.
Dehumidi cation can only be activated if the humidity exceeds the
dehumidi cation set point plus the di erential dFd, and furthermore:
Temp > Set – dS1 – dF2
It is deactivated if the humidity is below the dehumidi cation set point
and in furthermore:
Temp < Set – dS1 – dF2 – 0.5 °C
See the following graph for the description of this operating mode.

Con guration 2 (AdC = 2) - DiP 4 has no e ect
For the control of a classic reverse-cycle air-conditioning system, with
automatic cooling/heating changeover and proportional humidity
control using the CAREL compactSteam humidi er.
Automatic operating mode is signalled on the display by the AUTO
symbol, next to the set point.
There are two set points, one for cooling and the other for heating, and
both can be set.
The mode switches between cooling and heating automatically
according to the room temperature measured.
The two set points are set by pressing the SET button or the UP or DOWN
button,  rst the cooling set point is displayed and then the heating set
point, the controller automatically checks that there is a di erence of at
least 1°C between the two set points.
Relay 1 controls the heating/cooling signal.
The analogue output controls humidi cation.
Relay output 2 manages the changeover in mode.
See the following graph for the description of this operating mode.
