Changing the control parameters
To optimize the control performance, a number of control parameters can be adjusted. This can also be
made during operation without opening the controller.
Do you want to change the control parameters of the heating and / or cooling setpoints in the normal or
energy saving mode? Or do you want to increase / decrease the switching differential in heating and
cooling mode?
Then, proceed as follows:
(For factory settings, see above under “Commissioning)
Sensor calibration
If the room temperature displayed by the controller does not match with the temperature effectively
measured, the temperature sensor can be recalibrated. For that purpose, parameter P09 must be
changed
Proceed as described under “Changing the control parameters” and follow steps 1 through 3 to
select parameter P09.
With step 4, the room temperature displayed can now be matched to the temperature
effectively measured. Each push of the + or – button changes the temperature by + or – 0.5 °C
up to a maximum of + / - 3 °C. With step 7, the recalibration is automatically stored 10 seconds
after the last readjustment..

2. Press the + and – buttons simultaneously for a min. of 3 and a max. of 5 seconds.
Release them and within 2 seconds, press the + button again for 3 seconds. The
display will show “P01”.
3. Select the required parameter by repeatedly pressing the + or – button:
4. Press the + and – buttons simultaneously, the current value of the selected
parameter appears, which can be changed by repeatedly pressing the + or –
button.
5. By pressing b and - simultaneously again or 5 seconds after the last press
of a button, the last parameter will be displayed again.
6. If you wish to display and change additional parameters, repeat steps 3 through 5.
7. 10 seconds after the last display or setting, all changes will be stored.
