Checkthattherequiredcontrolledcomponents(actuator,pumpetc.)areconnectedtothecorrectterminals.

Checkthatallsensors/signalsareconnectedtothecorrectterminals(see'Electricalconnections').

Mountthecontrollerandswitchonthepower.

IstheECLApplicationKeyinserted(see'InsertingtheApplicationKey').

DoestheECLComfortcontrollercontainanexistingapplication(see'InsertingtheApplicationKey').

Isthecorrectlanguagechosen(see'Language'in'Commoncontrollersettings').
