24V Interface

Carrier VRF

The 24V Interface for Carrier VRF (Variable Refrigerant Flow) systems is a device that enables the use of a conventional 24VAC thermostat with indoor units. The Interface receives 24VAC signals for Cool, Heat, and Fan. This translates these commands to the system's communication protocol and sends the commands to indoor unit over the HA / HB communication bus.  

Compatible Units

The 40VM900008 is compatible with Carrier VRF indoor units.
