Switch the adjusting knob POWER
"10" to position 1. The display will
then light up, and after a few second
the heating appliance is ready to
operate.
Winter and summer operation
The heating appliance has a MODE "9"
key, by which the appliance can be
changed over from winter to summer
operation and vice versa.
The appliance is on winter operation, if
the LED "13" is illuminated. If the
outside temperature is connected to
the heating appliance, the changeover
from winter operation (heating and hot
service water) to summer operation
(only hot service water) can occur
automatically, if the outside
temperature measured is higher
than 20 °C.
In this situation, press the MODE key
"9", until the LED AUTO "14" lights
up. For deactivation of the automatic
changeover press the MODE key
again, until the LED AUTO "14"
goes out.
Note:
Adjustments made to the heating
temperature and the service water
temperature remain unchanged after a
power cut.
Adjustment of the heating
temperature and service water
temperature is undertaken at the
QAA 73.
