Start-up
6.2.3 Support ring
With some manufacturers' valves, the
part of the valve that protrudes into the
device has only a small diameter, which
causes the radiator thermostat to sit
more loosely on the valve. In this case,
the provided support ring should be
placed into the flange before installing
the radiator thermostat. You can then
mount the radiator thermostat again as
described above.

6.2.4 Danfoss RA adapter
The provided adapter is required to
attach to Danfoss RA valves.
The RA adapter has been manufac-
tured with pre-tension to provide
better fit. Use a screwdriver during
installation if necessary and bend the
adapter open slightly in the vicinity of
the screw.
Figure 7
Danfoss valve bodies have elongated
notches around their circumference,
which also ensure that the adapter is
properly seated when it snaps on.
During installation, please ensure
that the pins inside the adapter
are lined up with the notches on
the valve.
Please be careful not to trap your
fingers between the two halves of
the adapter!
After clipping onto the valve body,
please attach the adapter using the
provided screw and nut.
6.3 Adjustment run
When the batteries are inserted,
the motor retracts to simplify
installation. Meanwhile, "InS" and
the activity symbol ( ) are dis-
played.
Figure 8

After the radiator thermostat has been
mounted successfully, an adjustment
run (AdA) has to be performed to adapt
