6.2 Installation
Please read this section complete-
ly before starting the installation
process.
The Homematic IP Radiator Thermo-
stat is easy to install, and requires no
draining of heating water or interven-
tion in the heating system. No special
tools are required, nor does the heat-
ing have to be switched off.
The metal nut (A) attached to the radi-
ator thermostat can be used universally
and without accessories for all valves
with a thread size of M30 x 1.5 mm
from the most popular manufacturers.
An overview and information about
compatible manufacturers and valve
adapters can be found at
www.homematic-ip.com
Using the adapters supplied, the device
can also be installed on Danfoss RA,
Danfoss RAV and Danfoss RAVL radia-
tor valves
(see „6.2.4 Adapter for Dan-
foss" on page 24).
6.2.1 Removing a thermostat
In case of visible damage to the
existing thermostat, valve or heat-
ing pipes, please consult a spe-
cialist.
Remove the old thermostatic head
from your radiator valve:
• Rotate the thermostatic head an-
ticlockwise to the maximum value
(1). The thermostatic head then no
longer presses against the valve
spindle, making it easier to remove.
Figure 5
The thermostatic head may be held in
place in various ways:
• Union nut: Unscrew the union nut
in an anticlockwise direction (2).
The thermostatic head can then be
removed (3).
• Snap-on fastenings: Thermostatic
heads that are fastened this way
can be detached by turning the
fastener/union nut anticlockwise
a little. The thermostatic head can
then be removed.
