118 Condair MHR
9.5 Installation
1. Place a slotted screwdriver in the locking slots on the right-hand side of the humidistat and press
inwards until the housing cover pops open.
3. Connect wires of the connection cable to the terminals according to the wiring diagram.
3. Fasten the mounting plate with the connection unit at the intended location with two screws in the
ush-mounted or surface mounted box (see dimensional drawing).
4. Close the housing cover and click into place in the basic housing.

Notes on voltage The measuring location of the humidistat should be chosen so
that no water condensation can form on or in the device. This
is especially important when the device is operated with a volt-
age higher than 48V. If the voltage is high, there is a risk that
a voltage ashovers may occur if there is water precipitation on
the microswitch or on the connection terminals and thus destroy
the humidistat. At voltages below 48V, the humidistat can be
used up to 100 %rH.
Protection class I (according to EN 60 730)
Degree of protection IP 30 (according to EN 60 529)
Standards CE conformity, Low Voltage Directive 2014/35/EU
EMC directive 2014/30/EU according to DIN EN 60730-
1:2012-10 and DIN EN 60730-2-13:2008-09,
Function Humidication: Wire contacts 1 + 2
Dehumidication: Wire contacts 1 + 4
If the relative humidity Fx (actual value) drops below the set
point value Fw, contacts 1/4 open and contacts 1/2 close.
