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
Description
ER1
Short circuit on floor sensor
ER2
Open circuit on floor sensor /
Missing floor sensor
ER3
Short circuit on room sensor
ER4
Open circuit on room sensor
ER5
Check sensing mode
The floor sensor can be replaced by a new one. In the
event of malfunction of the room sensor, the entire
thermostat must be replaced.
The floor sensor has got the following temperature/
resistance values:
temperature
Resistance
15°C
15.8 kΩ
20°C
12.5 kΩ
25°C
10.0 kΩ
30°C
8.0 kΩ
35°C
6.5 kΩ
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.
