Connect the power supply (230 V, AC, single-phase,
50 Hz) to the terminals phase L, neutral N and protec-
tive earth PE of the machine as shown in the illustra-
tion.
Potential-free contacts are provided for the control
inputs of the machine. Connect the corresponding
wires to the terminal as shown in the illustration.
There are two different input signals:
▪ DH: Request for air dehumidification
▪ VENT: Request for continuous fan operation
The REHAU control system NEA SMART 2.0 can be
used to control the dehumidifier. For correct connection
and correct use, observe the relevant technical
information and the locally applicable regulations.
If required, the REHAU actuator UNI 230 V, which is
assigned to the water circuit of the dehumidifier, can
be connected to the terminals of the ZONE VALVE
output signal. When using an on-site actuator, please
ensure that the nominal data of this actuator match
the output signal 230 V AC 1 A Max of the
dehumidifier.
Use separate cables for the power supply, the input
signals and the output signal and the cable glands
provided at the factory for this purpose. If three cable
glands are required for this, an additional cable gland
must be installed on site at the location of the cable
grommet. The factory-fitted cable glands are suitable
for cables with an outer diameter of 6 – 12 mm.
Before using the unit, the electronics box cover must
be properly closed again.
