is in its correct position. The controller switches itself on.
Do you want to change the operating mode?
By pressing , you can change the operating
mode. The sequence is started from normal operation,

Then, the setpoint of the selected operating mode will
be maintained.
In normal operation, the display shows , in energy
saving mode, the display shows , and in frost
protection mode, the display shows .
Default operating mode is “Normal operation”.
When the unit is first powered up,

Are your rooms too warm or too cold?
+
To increase or decrease the room temperature
setpoint in increments of 0.5 °C, proceed as follows:
•Press to select the operating mode
corresponding to the set point that you want to
change
•Press
+or once
The setpoint display starts flashing
•Press these buttons again to change the
temperature setpoint in the range 5 ... 35 °C
5 seconds after the last push, the new temperature
setpoint will automatically be saved. The display stops
flashing and shows the room temperature currently
measured.
Note:
The setpoint in energy saving mode can be set to
0 °C. This means OFF or, in other words, the
controller is not active in energy saving mode and
symbol will not appear on the display.
Risk of frost!
If you want to have frost protection, press to
select frost protection mode, the display shows
and default value is 5 °C. If the room temperature falls
below the preset frost protection level, it will
automatically activate the heating output.

•Air out the rooms for short periods of time only, but properly, with the
windows wide open
Do you want to switch on DHW heating?

Do you want to change the batteries?
•Get 2 new alkaline batteries type AA, 1.5 V
•Remove the battery holder, then the batteries, insert the new batteries and
replace the battery holder
•Make certain the old batteries are disposed of properly, in compliance with
environmental requirements
Recalibrating the sensor
+
+
If the room temperature displayed by the controller does
not match the temperature effectively measured, the
temperature sensor can be recalibrated.
Follow the steps below to recalibrate the sensor:
1. In normal operation, press the “+” and operating mode
changeover buttons simultaneously for more
than 3 seconds, switching the system to calibration
mode.
2. The display format in calibration mode is the same as in
normal or energy saving mode, but with the temperature
digits flashing at 1Hz. You can adjust the temperature to
the desired value with the “+” or “-” button at 0.5 K per
step. The maximum adjustable range is +/- 3 K.

3. If no button is pressed for 5 seconds, the system will
return to the initial operating mode and the temperature
is set to the new value.
Note that the operating mode changeover and DHW
buttons are deactivated in calibration mode.
