Installation

Please read this entire section before starting the installation.
The Homematic IP Radiator Thermostat is easy to install and can be done
without draining heating water or intervening in the heating system. No
special tools are required, nor does the heating have to be switched off.
The metal nut (A) attached to the radiator thermostat can be used uni-
versally and without accessories for all valves with a thread size of M30 x
1.5 mm from the most popular manufacturers. An overview and informa-
tion 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 radiator
valves type Danfoss RA, Danfoss RAV and Danfoss RAVL (see see „5.2.4
Adapter for Danfoss" on page 49).
5.2.1

Removing a thermostat

In case of visible damage to the existing radiator, valve or heating
pipes, please consult a specialist.
Remove the old thermostatic head from your radiator valve:
• Rotate the thermostatic head anti-clockwise to the maximum
value (1) (see figure 6). The thermostatic head then no longer
presses against the valve spindle, making it easier to remove.
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 anti-
clockwise a little. The thermostatic head can then be removed.
