idle period of 24 hours.
Anti-seizingpumpprotection
Summermode
The winter mode is deactivated by rotating the heating water temperature selector
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.
Setting
Wintermode (settings 2 to 8)
In winter mode, the boiler heats the ow 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.
Emissionstestmode
The emissions test mode is activated by rotating the heating water temperature
selector into position. The illuminated signal ring ashes 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 ow temperature has been exceeded. To reactivate, turn
the heating water temperature selector anti-clockwise and then back into position.
