Note:
The number of times the condensing boiler can be started in heating mode is limited
electronically. This limit can be bypassed by pressing the reset button. Then, the boiler
starts immediately, as soon as there is a heating demand.
In summer mode, the circulation pump operates for approx. 30 seconds after a maxi-
mum idle period of 24 hours.

Wintermode (positions 2 to 8)
In winter mode, the boiler heats to the temperature selected at the heating water temper-
ature controller. According to the pump operating mode, the circulation pump operates

Winter mode is disabled by rotating the heating water temperature selector into posi-
tion . In other words, the boiler will then operate in summer mode. Summer mode
