Important:
If the setpoint of protection is set to OFF (factory setting), the controller will not be
active.
Risk of frost!
Do you want to change from heating to cooling mode?
/
The changeover between cooling and heating is done by a remote changeover

8. Switch to comfort operation with the button.
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
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.
