ENGO Controls EPC11 Pump Controller for Heating and Hot Water Circulation

The ENGO Controls EPC11 is a dedicated controller designed for managing central heating (CO) and domestic hot water (CWU) circulation pumps. It provides precise temperature regulation and essential protective functions to ensure efficient and reliable pump operation.

Advantages

Equipped with a digital LED display and NTC temperature sensor, the EPC11 offers accurate temperature control with a hysteresis of 2°C. Built-in anti-stop and anti-freeze functions protect the pump from seizing and freezing, extending its lifespan. The wall-mounted design and simple interface make installation and operation straightforward.
