Emergency programme with sensor error
In the event of sensor errors, the controller operates in an emergency programme. All
zones with an intact sensor are regulated as normal. The temperature is only dis-
played with the intact sensors.
If more than 2 sensors are defective, the controller still continues to operate as long
as at least 1 zone is intact. The zones with the defective sensors are then handled as
if their temperature corresponds precisely to the mean value of the intact zones.
