PL-M2000-MUA Prolon

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 management 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 temperature 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 temperature limits and minimum delays • Manual input to deactivate lockout mode
