Operation
After configuration, simple operations
are available directly on the device.
• Temperature: Turn the control
wheel (C) to the right or left to
manually change the temperature
of the radiator. In automatic mode,
the manually set temperature will
remain the same until the next
point at which the schedule chang-
es. Afterwards, the defined heating
schedule will be enabled again.
During manual mode, the temper-
ature remains activated until the
next manual change.
• Boost function:Press the control
wheel (C) briefly to activate the
boost function for heating up the
radiator quickly for a short time by
opening the valve. There will be a
pleasant room temperature right
away because of the radiated heat.
If you have paired the device with
a Homematic IP Home Control
Unit or Homematic IP Access
Point, you can configure the LED
colour of the control wheel (C) for
various actions directly in the app.
A long press on the control wheel
(C) toggles between automatic
mode and manual mode.
8 Changing the batteries
If the symbol for empty batteries ( ) ap-
pears in the display or in the app, please
replace the used batteries with two new
LR6/Mignon/AA batteries. Pay attention
to the correct battery polarity.
To insert new batteries, proceed as
follows:
• Open the battery compartment
by pulling the cover of the bat-
tery compartment (F) off upwards
(see
figure).
• Remove the batteries.
• Place two new 1.5 V LR6/Mignon/
AA batteries in the battery com-
partment, observing the polarity
marks.
• After inserting the batteries, pay
attention to the flashing sequences
of the LED
(see „9.4 Error codes and
flashing sequences" on page
Once the batteries have been inserted,
the radiator thermostat will perform a
self-test and an adjustment run, if re-
quired (approx. 2 seconds). Afterwards,
initialisation is carried out. The LED test
display will indicate that initialisation
is complete by lighting up orange and
green.
