Error 4
The temperature sensor provides invalid readings.
Carry out a hardware reset, see page 116.
If an optional external temperature sensor (Remote Sensor
9485-F) is connected, please check the cabling.
Please contact the RADEMACHER Service department if
only the internal sensor is used and the problem still
persists, see page 124.
The readings of the sensors can be checked in menu 9.7.7,
see page 92.
The controller switches to an emergency mode in the event
of a faulty sensor by switching on for 6 minutes (30%) and
switching off for 14 minutes (70%). This prevents excessive
cooling of the room and overheating of the floor.
