Installation
5.1.1 Mounting the radiator thermostat
In case of visible damage of the existing radiator, valve or
heating pipes, please contact a specialist.
Remove the old thermostat dial from your radiator valve (see section 3).
• Rotate the thermostat dial to the maximum value (N) (anti-
clockwise). The thermostat dial then no longer presses against
the valve spigot, making it easier to remove.
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 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 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).
After removing the old thermostat dial you can mount the Home-
matic IP Radiator Thermostat with the union nut (A) to the radiator
valve (see figure 4).
If required, you can use the supplied adapter for Danfoss RA valves
(see „5.1.1 Mounting the radiator thermostat" on page 42) or the
supplied support ring (see „5.1.3 Support ring" on page 44).
