Installing the room temperature sensor

When selecting the location, bear in mind that the room tem-
perature sensor must not be subjected to any direct radiant
heat. For optimum room temperature regulation, we recom-
mend that the room temperature sensor be fitted above the
entrance door.
Please ensure that the room temperature sensor is
always attached to a vertical wall. There may be no ob-
structions preventing the room air from flowing around it.
Drill a hole 10 mm in diameter. Guide the connection cable
through the drillhole from behind and plug the cable end to
the sensor by means of an insulated connector plug (there is
no need to be concerned about polarity). Slide in the room
temperature sensor and lay the cable end with the two insu-
lated connector plugs to the heating electronics unit (extend
to a maximum overall length of 10 m using 2 x 0.5 mm² cable
if necessary).
The provided room temperature sensor must always be
connected, otherwise the heater will switch to fault.

Installing the control panel

Reserve a place for the control panel at an easily visible loca-
tion. The scope of delivery includes a 3-metre connecting
cable (51).
Drill 55 mm dia. hole. Insert the plug (52) on the connection
cable (51) into the control panel (50). Make sure that the plug
engages in the control panel. Clamp the connecting cable (51)
into the control panel cable guide, slide through towards
the rear and route to the heater. Attach control panel with
4 screws (53) and fit the cover frame (54).

Electrical connections

Route connecting cables in such a way that they cannot
chafe. Please also use leadthrough bushings or edge protec-
tion profiles where there are sharp edges such as metal panel
leadthroughs. The connecting cables must not be attached to
or come into contact with metal surfaces, the exhaust duct or
warm air ducts.
The electrical connections are located under the connection
cover (60). The cover can be removed by pressing and simul-
taneously sliding it in the direction of the arrow. When remov-
ing or installing the connection cover on the connection ca-
bles, make sure that the cables are not pulled out or become
pinched.

All connections to the unit should be made with sagging con-
nection cables. This will prevent condensation water from run-
ning down the connection cables and into the unit.
The connecting cables and plugs must not be subjected to
force. Bundle connecting cables (see figure) and secure each
one to housing using a cable binder in order to provide strain
relief.
