Overview
When connecting the zone control interface (UTY-CDPXZC) to the indoor unit, a specific wiring loom (harness) is required to ensure reliable communication between the indoor PCB and the zone controller board.
This harness facilitates the connection between terminal CN6 on the indoor unit and the corresponding input on the zone-control-interface.
Component Description
The wiring loom / harness connects:
The indoor unit main PCB (CN6 terminal)
To the Zone Control Interface (UTY-CDPXZC) board
It is supplied as an accessory with new controllers but can also be purchased separately for servicing or retrofitting.

Installation Notes
Route the loom through the cable hole of the zone control interface as shown in the diagram.
Connect the harness securely to CN6 on the indoor PCB.
Use the included small cable ties to secure the harness and prevent movement.
