M2000 Series Boiler Controller

The built-in microprocessor offers precise digital control to maximize performance. The available control sequences are fully configurable, either locally or remotely, with the free Prolon Focus software. The M2000 uses proportional-integral (PI) control loops to optimize boiler management and offers a variety of functions such as outdoor reset for the supply water tempearture, lead-lag sequences for pumps and boiler stages, optional valve and boiler modulation, safety limits and more.
