7.5 Automatic night reduction
Conditions for automatic night reduction:
Pumps installed in gas boilers with low water capacity must never be set
to automatic night reduction:
If the heating system does not supply enough heat to the radiators, check whether
the automatic night reduction function is active. If necessary, deactivate the automatic
night reduction function.
To ensure that night reduction functions properly, the following requirements must be met:
1. The pump must be installed on the supply
2. The heating system must be equipped with automatic temperature adjustment on the supply.
How automatic night reduction works
Press the button to activate the night reduction function. If the adjacent
highlighted field is lit, the night reduction is activated and the pump automatically switches
between normal operation and night reduction. Swiching depends on the flow temperature.
The pump automatically switches to night temperature reduction if the flow temperature
drops by more than 10°-15°C in 1 hour.
Switching to normal operating mode takes place immediately as soon as the
flow temperature rises again by 3°C.
