Remote controller wiring and remote controller inter-unit wiring
The remote controller wiring (communication line) and AC208 - 240 V wires cannot make contact with each other
and cannot be put in the same conduits. It may cause problems in the control system due to noise or other factors.
* Varies depending on the remote controller used.
