Start-up
Remove the old thermostat dial from your radiator valve.
•
Rotate the thermostat dial to the maximum value
(1)
anti-
clockwise
(see figure 6)
. 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
(2)
. The thermostat head can then be removed
(3)
.
•
Snap-on fastenings:
Thermostat dials that have been attached
using this method can be easily released by giving the lock/union
nut a slight turn in the anticlockwise direction
(2)
. The thermostat
head can then be removed
(3)
.
•
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 head from the valve
(3)
.
•
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 Homematic
IP Radiator Thermostat with the union nut
(A)
to the radiator valve
(see
figure 7)
.
If required, you can use the supplied adapter for Danfoss RA valves (see
see „5.1.1 Direct pairing with a Homematic IP device“ on page 37) or
the supplied support ring (see see „5.2.3 Support ring“ on page 42).
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
(see figure 8)
.
The Danfoss valve bodies have elongated notches around their
circumference, which also ensure that the adapter is properly seated
when it snaps on.
