Connecting the control lines
Remote ON/OFF
If you want to operate the device optionally via remote mode,
e.g. from a remote control centre or factory master control
system, connect the external switching contact (N/O contact) to
the respective terminals. The control voltage amounts to 24 V
DC (for detailed information please refer to the wiring diagrams
in the technical annex).
Control via external hygrostat (% RH)
You can control the device via an external hygrostat (option).
The control voltage amounts to 24 V DC.
The external hygrostat is to be connected to the terminal strip in
accordance with the wiring diagram (see Technical annex).
If the relative humidity level falls below the set target value, the
contact closes and terminates the dehumidification process.
The illustrations below show the terminals for remote switch-on
and relays with potential-free contacts:
