7.ꢀTROUBLESHOOTING
In the event of damage or malfunction of one of the temperature sensors, the heating output cuts off (fail safe) and an error
code is displayed.
Error Code
ER1
ER2
ER3
ER4
Description
Short circuit on floor sensor
Open circuit on floor sensor / Missing floor sensor
Short circuit on room sensor
Open circuit on room sensor
Check sensing mode
ER5
The floor sensor can be replaced by a new. In the event of malfunction of the room sensor, the entire thermostat must be
replaced (Error 3 or Error 4).
Error 5 occurs if the thermostat is set in Room Sensing Mode and the floor sensor is installed.
To resolve the error change the sensing mode in Floor sensing or Room sensing with floor temperature limiter. Otherwise,
remove the floor sensor to work in room sensing mode. The floor sensor has got the following temperature/resistance values:
Temperature
15°C
20°C
25°C
30°C
Resistance
15.8 kΩ
12.5 kΩ
10.0 kΩ
8.0 kΩ
35°C
6.5 kΩ
