Troubleshooting

When a fault occurs, the eTOUCH ECO
turns the heating off. The display then
shows an error code.

E2 Interruption room sensor.
E3 Short circuit floor sensor.

Please note that the floor heating system is
a high voltage system and any faults must
therefore be rectified by an authorised
electrician.
