The marking on the clock-ring indi-
cates when comfort temperature is
chosen and when economy set-back
is switched on. A
fl
ashing point indi-
cates 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 thermostat 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 devireg
™
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.
