There are different ways of fixing the
position of the thermostat dial:
• Union nut: Unscrew the union nut
in an anticlockwise direction (O).
The thermostat dial can then be
removed (P).
• Snap-on fastenings: Thermostat
dials that are fastened this way can
be detached by turning the faste-
ner/union nut a little bit counter-
clockwise (O). The thermostat dial
can then be removed (P).
• Compression fitting: The thermos-
tat dial is held in place by a moun-
ting ring which is held together
with a screw. Loosen this screw
and remove the thermostat dial
from the valve (P).
• Threaded connection with set
screw: Loosen the set screw and
remove the thermostat dial (P).
• Remove the protective film from
the adhesive strips.
• Press the assembled wall thermos-
tat with the back side to the wall in
the position where it should subse-
quently be attached.

6.2.2 Mounting the radiator
thermostat
After removing the old thermostat dial
you can mount the Homematic IP Ra-
diator Thermostat with the union nut
(A) to the radiator valve.
Figure 5
If required, you can use the sup-
plied adapter for Danfoss RA valves
(see „6.2.4 Danfoss RA adapter" on
page 31)) or the supplied sup-
port ring (see „6.2.3 Support ring").
6.2.3 Support ring
The valves from different manufacturers
may have tolerance fluctuations that
make the radiator thermostat more
loosely seated on the valve. In this case,
the provided support ring (Q) should be
placed into the flange before mounting
the radiator thermostat.
