Troubleshooting - EBECO EB-Therm 55 Manual

Delay between turning off and on
There is a built-in delay in order to
avoid unnecessary wear and tear on
internal components and to extend
the life of the thermostat. If you raise
the desired temperature so that the
thermostat comes on, and then lower
it shortly afterwards, then it takes 30
seconds before it goes off again.
Key lock button
When you have found a suitable set-
ting for the temperature you can lock
the knob. This prevents the control
being changed accidentally.
See illustration below. First remove
the knob. Then move the two plastic
parts so that they define the interval
required. Replace the knob.

Troubleshooting

The underfloor heating
Important
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.
Test values for floor sensor
The following values apply when
the floor sensor's measurements are
checked.
