Johnson Controls LX-PFCUA-1, LX-PFCU-1 LX Series Powered Fan Coil Unit (PFCU) Controller

LX Series Powered Fan Coil Unit (PFCU) Controller

The LX Series Powered Fan Coil Unit (PFCU) is a microprocessor based fan coil unit controller designed to control any fan coil unit application. The PFCU controller uses the LonTalk® communication protocol and is LONMARK® certified using the fan coil functional profile #8501. The PFCU controller is compatible with the LN-PSTAT Sensor, which is a communicating sensor with 2-line Liquid Crystal Display (LCD). Functionality includes setpoint adjustment, fan speed control, indoor temperature display, and occupancy state display.

• software — features a wizard for configuring the software. You can easily configure all features, including input and output types and properties and heating and cooling stages
• robust hardware — features a fire retardant plastic enclosure with a separable base plate that allows the base and connectors to be shipped to the site for installation while engineering is done elsewhere
• interoperability — supports LONWORKS® technology for peer-to-peer communication between controllers
