First Switching On Of The Power Supply - Bitzer LHL3E/2EES-2Y Instructions De Service

First switching on of the power supply

After switching on the power supply, the controller car-
ries out an automatic self-test. During this process, the
display is flashing.
Ex factory the operation of the controller in a newly de-
livered ECOLITE condensing unit is not enabled and,
for this reason, the display should show the status
"OFF" after having switched on the supply voltage.
Once the controller has been parametrised, it can be
enabled using the parameter OnOF (F4⇒init⇒OnOF) if
the commissioning of the refrigerant circuit allows it.
The condensing unit can also be enabled by means of
an external signal (potential-free relay contact). For
this, a digital input of the controller has to be configured
for external release of the condensing unit. This func-
tion is not activated ex factory.
