Wiring diagram
HVAC module engineering wiring reference — FCU/VRF/floor heating protocol and equipment integration. Per signed drawing set.
Installation notes
- module address must be at detailed design phase with RCU circuit schedule, scene schedule planned together
- DIN rail/low-voltage cabinet installation must reserved cooling space, terminals torque per factory specification
- Wire per project drawing; signed projects use factory shipment drawings
- after power-on with RCU commissioning: output actions, bus communication, scene linkage item-by-item acceptance
- HVAC protocol and address table must sync with HVAC construction drawings during detailed design
