Information on Marking Radio and HVAC Controller Head Connectors if Disconnected at Same Time

Important: Mark the connectors when both the HVAC controller and radio are removed at the same time to avoid confusion during reconnection.

The radio and the HVAC controller head use the same type of connector. The opportunity exists to inadvertently switch these connectors whenever the Radio and HVAC controllers are disconnected at the same time. During such operations, please mark the connectors during removal.
