Prolon PL-M2000-RTUS : Single-Zone 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 RTUS 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 RTUS 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.
Features
- Designed for unitary systems using a single space temperature sensor
- Internal clock with configurable schedules and calendars
- A manual/off/auto switch for each of the eight outputs
- Remote monitoring and configuration with FREE Prolon Focus software
- Stand-alone or networked (up to 127 nodes)
- Proportional integral (PI) control loops maximize performance
