The EFC package from National Environmental Products Ltd. (Neptronics) is a BACnet® communicating thermostat and controller module designed for fancoil applications. This intelligent LCD thermostat with its BACnet MS/TP communication provides a quick connection between the controller and the fancoil via the RJ45 port. Applications are suitable for two- or four-pipe systems, three-speed or modulating fan control, on-off or analog valve control, on-off / pulse, or analog reheat. The thermostat comes with an easy to use four push button setup for scrolling through menus and adjusting parameters such as setpoint and occupancy override.
