Fan Coil Controller: eZFC-424R4-24
The eZFC-424R4-24 is a native BACnet® configurable controller optimized for fan coil applications. The eZFC features line voltage relays for direct switching of fan motor loads eliminating the need for external relays.
The eZFC communicates using BACnet MS/TP on its RS-485 main LAN port. It also has a RS-485 subLAN port for the optional addition of a BACstat smart network sensor.
The eZFC-424R4 covers a wide range of fan coil configurations including multi-speed fan control, 2 pipe or 4 pipe systems with analog, tri-state, binary or thermal valve actuator(s).
The eZFC-424R4 comes pre-loaded with a simple to configure factory algorithm.
