Operation Manual

09-10
• Heating without controlled water tempera-
ture: Turn the switch to operative setting (d).
Turn the knob (a) to the desired setting for the
thermostat (1-5). The green LED (b) for ope-
ration will shine; at the same time, it shows
the setting for the room temperature you have
selected. The yellow LED (g - warm-up phase
for the water) shines only as long as the water
temperature is below 5° C. The device auto-
matically selects the required power setting.
After the room temperature set on the ope-
rating device has been reached, the burner
turns itself off. The hot-air fan continues to run
at low speed for as long as the exit tempe-
rature (on the fan) is higher than 40° C. If the
boiler has been lled, the water is automati-
cally heated as well. The water temperature
then depends on the thermal output that is
given off and the heating period required to
reach room temperature.
• Heating with an empty water system: Turn the
switch to operative setting (d). Turn the knob
(a) to the desired setting for the thermostat (1-
5). The green LED (b) for operation will shine;
at the same time, it shows the setting for the
room temperature you have selected.
The yellow LED (g) will shine only when the
temperature in the device is below 5° C. The
device automatically selects the required po-
wer setting. After the room temperature set on
the operating device has been reached, the
burner turns itself off.
To turn off the device:
• Use the switch to turn off the heating (setting
f). The green LED (b) will turn off.
If the green LED (b) blinks after you
switch the heating off, the return
water is activated to reduce the tem-
perature of the device. This will stop
after a few minutes and the green
LED (b) will turn off.
In case of malfunction, the red LED
(h) will shine. Possible causes of de-
fects are given in the manufacturer’s
instructions for searching for defects.
