Hi team
GRCU typically used to control FCU guestroom of chiller system. How about solution for GRCU to control indoor unit(IDU) of VRV system?
As I known, all IDU are controlled automatically by signal loop wiring to Outdoor unit, so the only solution to control indoor unit is logical interface GRMS system with VRV system, isn't it.
Please give me advice.
Thanks

There are multiple ways to do it
It normally depends on project to project and on which is the brand of AC being used in the hotel .
