Remove the old thermostat dial from your radiator valve.
• Rotate the thermostat dial to the maximum value
(N) anti-clockwise (see figure 4). The thermostat
dial then no longer presses against the valve spin-
dle, making it easier to remove.
There are different ways of fixing the position of the ther-
mostat dial:
• Union nut: Unscrew the union nut in an anti-
clockwise direction (O). The thermostat head can
then be removed (P).
• Snap-on fastenings: Thermostat dials that are
fastened this way can be detached by turning the
fastener/union nut a little bit counter-clockwise
(O). The thermostat dial can then be removed (P).
• Compression fitting: The thermostat dial is held
in place by a mounting ring which is held togeth-
er 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).
After removing the old thermostat dial you can mount the
Homematic IP Radiator Thermostat with the metal nut (A)
to the radiator valve (see figure 6).
If required, you can use one of the supplied adapters for
Danfoss valves (see „5.2.2 Adapter for Danfoss" on page
