Operation and troubleshooting

Once the installation and the hydraulic and electrical con-
nections are completed, the ecoLEVEL condensed water
pump is ready for operation. The green LED lights up. The
operation is self-regulating and does not require any fur-
ther manual control.
6.1

LED display of operating status or faults

On the front of the ecoLEVEL condensed water pump cas-
ing, there are two LEDs (¬ fig. 6.1), items 1 and 2) which
indicate the operating status or faults of the ecoLEVEL
condensed water pump.

Faults

The ecoLEVEL condensed water pump can automatically
resolve short-term faults in the normal function sequence.
When the maximum permitted water level is reached, both
LEDs flash. If the water level cannot be reduced by pump-
ing, the red LED flashes. As a consequence, the safety cut-
out switch is triggered after approx. 10 seconds. A poten-
tial-free contact or the current circuit opens to switch off
the boiler.
If a corresponding connection to the boiler has been
installed, the boiler is switched off to prevent any further
condensed water from being formed.

Fault diagnostics and elimination

If the red LED flashes or remains lit for longer than
1 minute, there is a fault in the installation or a defect in
the pump.
> To eliminate this fault, check the following points:

safety cut-out switch is
triggered if this condition
is prolonged.
If a connection between
