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.
If you want to change the control parameters, proceed as follows:

Changing the batteries
1.
Get 2 new batteries of type AA alkaline, 1.5 volts.
2.
Within 1 minute: Remove the battery holder, then the batteries, insert new batteries and replace the battery holder.
3.
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 agree with the temperature effectively measured, the temperature sensor can be
recalibrated. For that purpose parameter P07 must be changed.
Proceed as described under "Changing the control parameters" and follow steps 1 through 3 to select parameter P07.
With step 4, the room temperature displayed can now be matched to the temperature effectively measured. Each push of the
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.

Energy saving tips without sacrificing comfort
●
Never allow room temperatures to exceed 21˚C.
●
Air out rooms for short periods of time only, but properly, with the windows wide open.
Subject to alteration
(all temperature settings can be made in increments of 0.5 K and the time in increments of 1 min.)
