Master/Slave System Configuration Error

What does E14 mean?

This error indicates incorrect DIP switch (SWS) settings on the indoor unit PCB for master/slave configuration, or an open circuit in the control wiring between master and slave units. This prevents proper communication and coordinated operation.

1. 1

   Verify the DIP switch (SWS) settings on the indoor unit PCB of both master and slave units are configured according to the system's master/slave documentation.

2. 2

   Check continuity and secure connections of the control wiring between the master and slave indoor units using a multimeter.
