Prolon PL-M2000-FCU : Advanced Fan Coil Unit Controller, 5 Digital Outputs, 3 Analog Outputs, 9 Universal Inputs, Economizer/DCV Control, 7 Day Scheduling, Duct Static Pressure with Bypass Damper or Supply Fan VFD, Modbus RTU (RS485)
The M2000 FCU Fan Coil Unit controller is designed to control a variety of 2-pipe and 4-pipe hydronic heating and cooling units. The on-board microcontroller offers precise digital control to maximize performance. The available control sequences are fully configu- rable, either locally or remotely, using free software. The M2000 FCU uses PI (Proportional-Integral) control loops to optimize HVAC management and offers a variety of functions such as 2-pipe automatic mode change based on water temperature, automatic purge cycles to verify water temperature and prevent stagnation in coils, secondary backup heat source control, and more. The M2000 FCU will share zone demand data when connected to a Prolon network.
