with a screw. Loosen this screw and remove the
thermostat dial from the valve (3) .
• Threaded connection with set screw : Loosen
the set screw and remove the thermostat dial (3) .
After removing the old thermostat dial you can mount the
DHC Radiator Thermostat with the union nut (A) to the ra-
diator valve (see figure 6) .
If required, you can use the supplied adapter for Danfoss
RA valves (see “5.2.2 Danfoss RA adapter” on page 20)
or the supplied support ring (see “5.2.3 Support ring” on
page 21 ).
5.2.2 Danfoss RA adapter
The provided adapter is required to attach to Danfoss
RA valves. The RA adapter has been manufactured with
pre-tension in order to provide a better fit. Use a screw -
driver during installation if necessary and bend the adapter
open slightly in the vicinity of the screw (see figure 7) .
The Danfoss valve bodies have elongated notches around
their circumference, which also ensure that the adapter is
properly seated when it snaps on.
During installation, make sure that the pins inside
the adapter are lined up with the notches on the
valve. Make sure that a suitable adapter for the
valve is properly clipped on.
Be careful not to get your fingers caught between
the two halves of the adapter!
After clipping the adapter onto the valve body, fix it using
the provided screw and nut.
5.2.3 Support ring
The valves from different manufacturers may have toler -
ance fluctuations that make the DHC Radiator Thermostat
more loosely seated on the valve. In this case, the provided
support ring should be placed into the flange before mount -
ing the accessory
(see figure 8)
.
5.3 Adaption run
Once the batteries have been inserted, the motor
reserves. Meanwhile, InS and the activity symbol
are displayed (see figure 9) .
After the DHC Radiator Thermostat has been mounted
successfully, an adaption run ( AdA ) has to be performed
in order to adapt the accessory to the valve. To do this,
proceed as follows:
1. As soon as AdA is displayed, press the menu/
boost button (G) to start the adaption run
(see fi -
gure 10) .
» AdA and the activity symbol are displayed du-
ring the adaption run (see figure 10) . During this
