Function and device overview
3 Function and device overview
With the Homematic IP Radiator Thermostat you can
conveniently regulate the room temperature via the
Homematic IP smartphone app according to individu-
ally tailored heating phases. According to your personal
needs, you can create three dierent heating profiles
with up to 6 heating phases per day.
In the climate control solution, the radiator thermostat
can simply be connected to the Homematic IP Access
Point. In connection with the Homematic IP Window /
Door Contact, the temperature is automatically reduced
during ventilation. For precise regulation of the room
temperature, the Homematic IP Wall Thermostat with
Humidity Sensor can measure the actual temperature of
a room and transmit the data to the radiator thermostat.
This ensures that the temperature is measured at the
right place in the room.
The radiator thermostat fits to all common radiator
valves and is easy to mount - without having to drain any
water or intervene in the heating system. With the addi-
tional boost function, cool rooms can be heated within
short by opening the heating valve.

• Jaga
• Siemens
• Idmar
By means of the adapters in the delivery, the device can
also be installed on radiator valves of type Danfoss RA,
Danfoss RAV and Danfoss RAVL (see „5.2.2 Adapter for
Danfoss“ on page 11).
5.2.1 Mounting the radiator thermostat
In case of visible damage of the existing radiator,
valve or heating pipes, please consult a specialist.
Remove the old thermostat dial from your radiator valve.
• Rotate the thermostat dial to the maximum value
(N) anti-clockwise (see figure 4). The thermostat
dial then no longer presses against the valve
spindle, making it easier to remove.
There are dierent ways of fixing the position of the
thermostat dial:
• Union nut: Unscrew the union nut in an anti-
clockwise direction (O). The thermostat head
can then be removed (P).

10
Start-up
• Snap-on fastenings: Thermostat dials that are
fastened this way can be detached by turn-
ing the fastener/union nut a little bit counter-
clockwise (O). The thermostat dial can then be
removed (P).
• 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 dial from the valve (P).
• Threaded connection with set screw: Loosen
the set screw and remove the thermostat dial (P).
After removing the old thermostat dial you can mount
the Homematic IP Radiator Thermostat with the metal
nut (E) to the radiator valve (see figure 6).
If required, you can use one of the supplied adapters for
Danfoss valves (see „5.2.2 Adapter for Danfoss“ on page
11) or the supplied support ring (see „5.2.3 Support
ring“ on page 15).

5.2.2 Adapter for Danfoss
One of the provided adapters is needed to attach to
Danfoss valves. The assignment of the suitable adapter
to the relevant valve can be found in the following il-
lustrations.
Please ensure that you do not trap your fingers
between the two halves of the adapter!
The RA and RAV adapters have been manufactured
with pre-tension in order to provide a better seat. Use
a screwdriver during installation if necessary, and bend
it open slightly in the vicinity of the screw (see follow-
ing figures).

5.2.3 Support ring
The valves from dierent manufacturers may have tol-
erance fluctuations that make the radiator thermostat
more loosely seated on the valve. In this case, the pro-
vided support ring (R) should be placed into the flange
before mounting the radiator thermostat (see figure 5).
5.3 Adaption run
Once the batteries have been inserted, the motor
reserves. Meanwhile, “ ” and the activity
symbol ( ) are displayed.

Replacing batteries
• Please pay attention to the flashing signals of the
device LED while inserting the batteries (see „8.4
Error codes and flashing sequences“ on page
21).
Once the batteries have been inserted, the radiator ther-
mostat will perform a self-test (approx. 2 seconds). Af-
terwards, initialisation is carried out. The LED test display
will indicate that initialisation is complete by lighting up
orange and green.
Never recharge standard batteries. Do not throw
the batteries into a fire. Do not expose batteries
to excessive heat. Do not short-circuit batteries.
Doing so will present a risk of explosion.
Used batteries should not be disposed of with
regular domestic waste! Instead, take them to
your local battery disposal point.
