What to do if E4 is flashing on my DEVI Floor Heating Systems display?
If the DEVI Floor Heating Systems thermostat displays 'E4' and is flashing, it means the thermostat has overheated and switched off as a safety measure. To resolve this, allow the thermostat to cool down for a while. After it has cooled, switch the thermostat off and then back on.
What to do if E5 or E6 is flashing on my DEVI Floor Heating Systems display?
If the DEVI Floor Heating Systems thermostat displays 'E5' or 'E6', it indicates a floor sensor issue. 'E5' means the floor sensor is short-circuited, and 'E6' means the floor sensor is disconnected. To troubleshoot, first check the sensor connections to ensure they are secure. If the connections are good, disconnect the two sensor wires and use an ohm meter to measure the resistance. Compare this value with the table in Technical Specifications.
