VRF AC host module
Part number: CVRFH
Description
The CVRFH eliminates the need for a separate C225 CPU and Smart Hub on every indoor unit in a VRF system. Install a single C225 on one indoor unit, then use a CVRFH + C325# on each subsequent indoor unit. Currently compatible with Mitsubishi Electric VRF and Daikin VRV systems only.
