4.1 Operating elements on the boiler control panel
4.1.1 Overview and brief description
All the important operating elements and electrical connections are integrated in the boiler switchboard. The electronics ensure
a smooth system operation.
Mains switch
Switching the gas condensing boiler on and off. When the heating system is on, the mains switch is illuminated green.
Collective fault signal
During normal operation, the collective fault signal is off. If it lights up this indicates a malfunction.
Pressure gauge
– Black pointer: Indication of the current water pressure in the heating system.
– Green range: Permitted water pressure range.
– Red pointer: Indication of the permitted minimum pressure.
The black pointer must be in the green range. If it is to the left of the red pointer, the water pressure must be raised by topping
up the system. If water needs to be filled frequently, please find out the reason for it and have the fault correct as soon as
possible.
