Control unit / Function / Operation
Winter mode (position 2 to 8)
In winter mode, the boiler heats to the temperature selected at the heating water thermo-
stat. According to the pump operating mode, the circulation pump operates constantly
(factory setting) or only in parallel with the burner activation/run-on time.
Summer mode
Winter mode is deactivated by rotating the heating water temperature selector into po-
sition . In other words, the equipment will then operate in summer mode. Summer
mode (central heating OFF) means = only DHW heating. Frost protection for the central
heating system and pump anti-seizing protection are, however, assured.
Emissions test mode
The emissions test mode is activated by rotating the heating water temperature selector
into position . The illuminated ring flashes yellow. After the emissions test mode
has been activated, the boiler will heat to the selected maximum heating output. Any
previous cycle block will be cancelled. The emissions test mode terminates after 15
minutes or when the maximum flow temperature has been exceeded. For a renewed
activation, turn the heating water temperature selector anti-clockwise and then back
into position .
Thermomanometer
The current heating water temperature is displayed in the top half. The water pressure
in the heating system is displayed in the lower half. In normal use, the water pressure
should be between 2.0-2.5 bar.
In summer mode, the circulation pump operates for approx. 30 seconds after a maximum
idle period of 24 hours.
The number of times the gas boiler can be started in heating mode is limited electro-
nically. This limit can be bypassed by pressing the reset button. Then, the equipment
starts immediately, as soon as a heating demand is present.
