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, it takes 30 sec
before it goes off again.
Operation time
The thermostat can display the opera-
tion time as a percentage for the last
24 hours and 7/30/365 days.
Press and navigate to UTIL. Press
to select. The display now shows the
operation time as a percentage for the
last 24 hours. You can then navigate
between the operation time as a per-
centage for the last 7/30/365 days.
LED

status of the thermostat.
Green light – the thermostat is on and
the underfloor heating is switched off.
