Troubleshooting
Important
The underfloor heating
system is an electrical power installa-
tion and any faults must therefore be
remedied by a qualified electrician.
Fault indication
In the event of damage or breakdown
of the floor sensor the thermostat
switches off and the light starts to flash
alternately green and red.
If the floor sensor should be defective
it can be replaced, provided that it is
installed in a spiral hose laid in the floor
as per instructions.
