Start-up
• Threaded connection with set screw: Loosen the
set screw and remove the thermostat head (3).
After removing the old thermostat dial you can mount the
radiator thermostat with the union nut (G) to the radiator
valve (see figure 7).
If required, you can use the supplied adapter for Danfoss
RA valves (see "5.2.2 Danfoss RA adapter" on page 58)
or the supplied support ring (see "5.2.3 Support ring" on
page 59).
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 better fit. Use a screwdriver during
installation if necessary, and bend the adapter open
slightly in the vicinity of the screw.
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, ensure that the pins inside the
adapter are lined up with the notches on the
valve. Ensure that a suitable adapter for the valve
is properly clipped on (see figure 8).
