The marking on the clock-ring indicates
when comfort temperature is chosen
and when economy set-back is
switched on. A fl ashing point indicates
the actual clock (every half hour).
If the temperature is lowered to mini-
mum (+5ºC), a frost symbol will appear
in the display, indicating that the ther-
mostat will maintain minimum +5ºC in
the room for frost protection.
If the temperature is turned below
+5ºC, the thermostat will switch off.
(Only possible with the timer off).
When the temperature is raised again
the thermostat will automatically
switch on.
If the Thermostat EFIT 540/550 only
uses a fl oor sensor, the display will
not show the actual temperature (5º to
35º), but a scale from 0 to 10.
