Winter mode (settings 2 to 8)
In winter mode, the boiler heats the flow temperature to the value set on the thermostat.
According to the pump operating mode, the circulation pump operates constantly (factory
setting) or only in parallel with the burner activation / run-on period.
Summer mode
The winter mode is deactivated by rotating the heating water temperature
into position. In other words, the boiler will then operate in summer mode. Summer mode
(heating OFF) means only DHW heating. Frost protection for the heating system and
pump anti-seizing protection, however, remain enabled.
Emissions test mode
The emissions test mode is activated by rotating the heating water temperature
selector into position. The illuminated signal ring flashes yellow. After the emissions test
mode has been activated, the boiler will heat with the selected maximum 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. To reactivate, turn
the heating water temperature
In summer mode, the circulation pump operates for approx. 30 seconds after a maximum
idle period of 24 hours.
