24 Hour backup in case of power cuts
If automatic temperature cutback is programmed and a
power cut of more than 24 hours occurs, the thermostat will
revert to the lowest temperature setting that has been used.
The display will flash indicating that a lengthy power cut
has occurred. The cutback program must be restarted.
The calibration setting is saved even after lengthy power cuts.
Quick start of temperature cutback
Start nighttime temperature reduction by pressing the
button marked . Start daytime temperature reduction by
pressing the button. The temperature will be reduced
to the desired setting for the chosen time period. This will
repeat automatically at the same time every week. (A more
detailed description follows later in the guide.)
Office function (OF)
The thermostat is also suitable for use in offices and simi-
lar spaces. The Office Function (OF) provides temperature
cutback every night and at weekends.
Child lock
The thermostat may be secured against undesirable tam-
pering by holding down both the and buttons until
the display shows two dashes: – –. Repeat the procedure to
unlock the thermostat again.
Occasional temperature override during a cutback
period
You may freely select a new temperature setting while
temperature reduction is ongoing without this being perma-
nently saved. It will continue until the cutback period ends.
Changing times and settings for temperature
cutback periods
Changing the time and temperature setting for cutback
periods is only possible by restarting the temperature
cutback program.
Permanently remove a temperature cutback
program
To delete a cutback program, push and hold down the
button (night) or the button (day) until its lamp dims
completely. When in Office mode, press and hold down
the button until the lamp is extinguished.

Reset the thermostat to factory default settings
Turn the power switch OFF. Press and hold down the
button while switching the heater back on. Continue to
hold down the button for about 20 seconds, until rE
flashes in the display. Release the button, and after a
short while 20 (degrees) will be displayed. Calibration will
revert to zero after resetting to default.
Cutback indicator
During a cutback period the or lamp will flash
slowly. When lit steadily, the lamp indicates that cutback
function is not currently ongoing, but will start at the
programmed time of the evening.
Calibration
(to make sure that the displayed tempera-
ture corresponds with the correct room temperature)
Should the actual room temperature and the thermostat’s
displayed setting not correspond, the thermostat may be
calibrated.
NB! Correct calibration depends on room temperature
being regulated by the heater’s thermostat alone. This is
shown by the red lamp lighting and dimming at regular
intervals. If necessary, adjust the thermostat up or down to
make the heater start working.
Now allow the heater to work at the same temperature
setting, preferably for at least 24 hours, keeping doors
and windows closed in the room. This ensures that the
heater’s thermostat alone is regulating the temperature of
the room.
Holding down on , press once on the key briefly.
Release .
°C will flash three times and the setpoint temperature is
displayed. Press the or key until the display shows
the same as the actual measured room temperature. Save
by pressing the button briefly.
The heater will now display the setpoint temperature
again, and after a while this will correspond with the
actual room temperature. It may be necessary to repeat the
calibration procedure to attain full correlation between
desired and actual room temperature.
