FIG. 9 - TROUBLESHOOTING
If the sensor is disconnected or short-circuited, the heating system
is switched off. The sensor can be checked against the resistance
table.
Error codes
E0: Internal fault. The thermostat must be replaced.
E1: Built-in sensor defective or short-circuited. Replace the ther-
mostat, or use the floor sensor only.
E2: External sensor disconnected, defective or short-circuited.
Reconnect the sensor if disconnected, or replace the sensor.
E5: Internal overheating. Inspect the installation.
