• Threaded connection with set screw:
1. Loosen the set screw.
2. Remove the thermostat dial (P) .
After removing the old thermostat dial you can mount the
Radiator Thermostat with the union nut (E) to the radiator
valve ( see figure 6 ).
If required, you can use one of the supplied adapters for
Danfoss valves (see „5.2.2 Danfoss adapter“ on page
17) or the supplied support ring (see „5.2.3 Support
ring“ on page 21).
5.2.2 Danfoss adapter
One of the provided adapters is needed to attach to Dan-
foss valves.
Be careful not to get your fingers caught between
the two halves of the adapter!
The RA and RAV adapters have been manufactured with
pre-tension in order to provide a better fit. Use a screw -
driver during installation if necessary and bend the adapt-
er open slightly in the vicinity of the screw (
see following
figures ).
5.2.1 Mounting the DHC Radiator Thermostat
In case of visible damage to the existing radiator,
valve or heating pipes, consult a specialist.
Remove the old thermostat dial from your radiator valve.
1. Rotate the thermostat dial to the maximum value
(N) anti-clockwise ( see figure 4 ).
» The thermostat dial no longer presses against the
valve spindle, making it easier to remove.
The thermostat dial could be fixed in different ways:
• Union nut:
1. Unscrew the union nut in an anticlockwise direc-
tion (O) .
2. Remove the thermostat dial (P) .
• Snap-on fastenings:
1. Unscrew the union nut in an anticlockwise direc-
tion (O) .
2. Remove the thermostat dial (P) .
• Compression fitting: The thermostat dial is held
in place by a mounting ring which is held together
with a screw.
1. Loosen the screw.
2. Remove the thermostat dial (P) .
