Prolon PL-M2000-RTU : Advanced RTU Rooftop 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 RTU rooftop controller is designed to control a variety of different rooftop units or HVAC air treatment equipment. 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 RTU uses PI (Proportional-Integral) control loops to optimize HVAC management and offers a variety of functions such as economizer, preheating, CO2 levels, dehumidification, static pressure control and more. The M2000 RTU also acts as a Master controller when connected to a Prolon network.
