1. Take off the cover.
2. Install the base. In case of wall mounting, fix the base to the wall with 2
Ø 4 mm screws and corresponding dowels based on the quality of the wall.
In case of installation on a mounting bracket, use a TS 35/7.5 bracket.
3. Make the electric connection.

6 Electric connection
For the connection of the voltage supply, the cable sections must be 1.5 mm² for 230 V. Depending on the voltage version of the base, it is possible to take L1 or
L and L2 or N, as well as the protective conductor, from the base. A temperature limiter/dew point sensor can be connected to the contact TB/%H in NC operation;
this contact cannot be used in NO operation. If no temperature limiter is connected, the connection TB/%H must be bridged (provided for at the factory). The bridge
must be removed as soon as a temperature limiter is connected. The temperature limiter must be a normally closed contact.
The wiring of the thermostats
depends on the present ba-
sis. For wiring purposes,
please observe the instruc-
tions of the thermostat or of
the respective component.
