A variety of functions

• Features a pump interlock function that controls the pump of the heat source simultaneously with the starting of the VRV-WII unit. This significantly simplifies operation and management.
• Employs DIII-NET to enable the shared use of the wiring between the indoor units, the VRV-WII unit and the central control wiring.
• Provides an auto address setting function and check function that detects connection errors in wiring and piping for easier installation.
• Water piping goes only to the VRV-WII unit, with refrigerant piping run in occupied spaces, making the system ideal for installing in spaces such as OA rooms, with no worry of water leakage or corrosion.

Easily responds to simultaneous heating and cooling needs.

By adding suction gas piping and a BS unit (sold separately), simultaneous heating and cooling operation can be provided by a single system.
