Tab. 5.b
Note: When LE=1 proportional and ON/OFF control overlap,
therefore modifying parameter DIF changes the di erential for
both.
Note: Passing to level 2 allows the two types of control,
proportional and ON/OFF, to be positioned independently.
Parameters dSA and dS1 can have both positive and negative values,
allowing the two types of control, proportional and ON/OFF, to be set as
desired.
5.3 (H) humidity control
This type of control is only possible on the models  tted with digital
humidity sensor (ADCD******, ADCF******)
It is used in simple applications to send a start signal to a humidi er or
dehumidi er.
The analogue output can only be used for humidi cation control.
Examples of using of the analogue output:
for proportional humidity control by CAREL humidi ers, for example •
compactSteam
as an additional step to the relay for humidity control.•
Dipswitch con guration:
dip1: ON
dip2: OFF
dip3: OFF
The control mode is selected using dipswitch 4 located on the rear.
dip4 = ON for humidi cation
dip4 = OFF for dehumidi cation

5.4 (T+H) temperature plus humidity
control
This type of control is only possible on the models  tted with digital
temperature + humidity sensor (ADCF******)
It is used in simple applications, with one stage for the temperature
and one for the humidity, to send a start signal to an air-conditioner or
heat pump/boiler via the relay. The analogue output is only activated in
humidi cation mode.
Dipswitch con guration:
dip1: ON
dip2: ON
dip3: OFF
Control is available in both cooling and heating (dip4).
