Prolon PL-M2000-MUA : Advanced Make Up Air 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 MUA make-up air controller is designed to control a variety of different make-up air units and systems. The on-board microcontroller offers precise digital control to maximize performance. The available control sequences are fully configurable, either locally or remotely, using free software. The M2000 MUA uses PI (Proportional-Integral) control loops to optimize HVAC mana- gement and offers a variety of functions such as outdoor reset for the discharge air temperature, building pressure control, CO2 control, safety limits, lockout mode and more.
Features
- Single, dual or variable volume sequences
- Configurable winter and summer sequences
- Discharge air temperature reset based on outside tempe- rature or zone demand
- Building pressure control or CO2 control using a variable frequency drive
- 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
- 5 digital outputs and 3 analog outputs equipped with resettable fuses
- Built-in protection sequences with configurable tempera- ture limits and minimum delays
- Manual input to deactivate lockout mode
