THB, THH, TVB and TVL fan coil unit packages are factory assembled and shipped loose for field installation and wiring; factory mounting is optional for some units. All TVS/TVR fan coil unit packages are factory assembled, installed, and wired.. The units are also designed to exceed the stringent quality standards of the institutional market, while remaining cost competitive in the light commercial segment of the market. Johnson Controls horizontal fan coil units set the new standards for quality, flexibility, and competitive pricing.

A Fan Coil Unit (FCU) is a key component of HVAC systems, used to control room temperature by circulating air through a chilled or hot water coil. Proper FCU connection detailing ensures efficient operation, easy maintenance, and balanced water flow within the chilled water system. This post provides a free AutoCAD DWG file showing the Typical Detail of FCU Connections, ideal for MEP and HVAC.. As with other machines, devices, and appliances, the term "piping" in fan coil units refers to the immediate system components (devices and accessories located in the hydraulic circuit between the heat exchanger and the coolant line) that directly support their operation. This means that the primary function of fan coils is to maintain a set air temperature in individual rooms or different.
