Fan Coil Unit Controller

The fan coil unit controller provide room temperature control for two and four pipe fan coil units with optional electric heating coils (W7752D2007) and can control single, two or three speed fans. The controller is provided with default configuration settings from the factory and is fully operable on installation. Using standard Echelon configuration tools, the controller can be configured with job-specific settings. A variety of optional wall modules interface with the FCU controllers and provide any or all of the following: set point adjustment, fan speed adjustment, and an occupancy bypass button. All wall modules include a space temperature sensor, however a remote C7068A return air sensor can also be used. The controllers can operate as stand-alone units or networked using the standard Echelon LonWorks® bus. Interfaces are provided for a wide range of actuator types. Heating systems can be water or electric, and cooling systems can be chilled water supply or compressors. Extensive timing and interlock features make the W7752 especially suitable for systems using electric heat and compressors.
