Define water system form then module—FCU et VRF share RCU scene linkage; differ dans protocol et valve control.
Path B· VRF multi-split
Common retrofit—VRF gateway à bret outdoor protocol; Bienvenue/away setpoints de RCU; panel may lock upper temp.
- Module:VRF gateway
- Risk: confirm bret et tested protocol before contract
