4 Commissioning
First make all electrical connections correctly
and only then carry out the commissioning!
▶ Follow all installation instructions for all
components and assemblies in the system.
▶ Only switch on the power supply when all
modules are set up.
NOTICE: Risk of damage to system through
pump failure!
▶ Fill and vent the system before switching
it on so that the pumps do not run dry.
4.1 Setting the coding card
When the coding card is in a valid position, the indicator lights
up green continuously. When the coding card is in an invalid
position or an intermediate position, the indicator does not
light up initially. It then starts to flash red.
