Burner anti-cycling time

To prevent frequent switching on and off of the burner and
thus prevent energy losses, an electronic restart lockout
is activated for a specific period each time the burner is
switched off. The burner anti-cycling time is only active for
the heating mode. Hot water handling mode during a burner
anti-cycling time does not affect the time function element.

Setting the pump output

The product is equipped with a speed-regulated high-effi-
ciency pump, which adjusts independently to the hydraulic
conditions of the heating installation.
If you have installed a low loss header in the heating install-
ation, you should switch off the speed regulation and set the
pump output to a fixed value.
▶
If required, change the setting of the pump speed, which
depends on the operating mode, under diagnostics code
d.14.
