11. Mounting
11.1 Mounting instructions
NOTICE
Incorrect measured values can result from
unsuitable installation location. Locate the
temperature sensor [9] correctly.
Avoid disturbing influences.
Avoid exposure to direct sunlight.
Do not use in an area prone to draughts,
hot or cold air, e.g. near stove, fridge,
radiator, refrigerator, air intake, disk
valve/internal grille, etc.
Do not install in a unit with other heat-
generating devices, e.g. a dimmer switch.
● Only install unit onto a dry, level surface.
Any installation position can be selected.
● Only connect the unit to a permanently
wired electrical installation after it has
been completely mounted.
● The unit may only be operated using the
voltage and frequency shown on the rating
plate.
● Be sure to observe the relevant regula-
tions for electrical installation; in Germany
this is particularly VDE 0100, with the
corresponding parts.
● Connection area for the PG screw connec-
tion [6] is suitable for connection cables
with an external diameter of 6 to 12 mm.
● Connect the temperature sensor to both
“sensor” connectors. Permitted cables:
max. 100 m long, 1.5 mm².
● Connection terminals for cable with a max.
cross section of 2.5 mm².
● A mains isolation device with contact
openings of at least 3 mm at each pole is
mandatory.
● Cooling or heating operating mode can be
set with jumpers. Switching state display
with LED [2].
● The degree of protection is only
guaranteed if installation is undertaken
correctly and if the cables are correctly fed
into the housing.
11.2 Unit mounting
1. Switch off power supply circuits and
prevent them from being started up again.
Attach a clearly visible warning sign.
2. Pull the rotary knob [11] off.
3. Remove the cover [10] (4 screws).
4. Use 4 screws to secure the bottom part of
housing to the wall. Suitable mounting
material is to be supplied by the customer.
5. Set the operating mode to heating or
cooling with jumper [3] (factory setting -
heating).
6. Set the differential gap between the on/off
temperature with the potentiometer [8]
(setting range 0.2...5 K).
