8.1
Setting the 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. Domestic hot water 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
.

Setting the bypass valve
Caution.
Risk of material damage caused by incor-
rect setting of the high-efficiency pump
If the pressure at the bypass valve is in-
creased (by turning it clockwise) and the
pump output is set to less than 100%, the
product may not operate correctly.
▶
In this case, set the pump output to
5 = 100% using diagnostics parameter
d.14
.
Condition
:
d.14
is set to 0 = auto
▶
Do not change the factory settings.
Condition
:
d.14
is set to 1 - 5
▶
Remove the front casing. (
