NPC2 Recirculation pump and ACM pump controller

The NPC2 controller is designed to manage heat transfer fluid (HTF) and domestic hot water (DHW) recirculation pumps in central heating systems with solid fuel boilers. Using temperature sensors, it automatically controls pump operation based on user-defined temperature settings and differential values. This ensures efficient heat transfer from the boiler to the DHW tank, improves system performance, and helps maintain optimal water temperatures while reducing energy consumption.
