Caution
If possible, use the pump modulation signal. This provides the
most accurate pump control.
If the automatic burner unit does not support pump modulation,
the pump will behave as an on/off pump.

Checklist before commissioning
6.1.1
Filling the system
Important
In order to be able to read off the water pressure from the control
panel, the boiler must be switched on. If the water pressure is too
low, the boiler or the boiler pump will not start.
1. Fill the central heating system with clean tap water.
Important
The recommended water pressure is between 1.5 and 2 bar.
2. Check the water-side connections for tightness.
6.1.2
Filling the siphon
The siphon is supplied separately with the boiler as standard (including a
flexible plastic drain hose and a transparent extension hose for the
automatic air vent). Fit the siphon under the boiler.
