Controller for central heating pump and DHW pump, ENGO EPC12HW, black, 230V 932362893

Pump control for CH and DHW – optimizing system performance

The EPC12HW controller is an intelligent solution for controlling the operation of a circulating pump in a central heating (CH) system and a domestic hot water (DHW) pump. The device automatically turns on the CH pump when the temperature in the boiler exceeds the set value, ensuring efficient heat distribution. The DHW pump, in turn, starts based on the temperature difference between the boiler and the tank, operating until they are equalized or the desired water temperature is reached. This not only ensures thermal comfort but also helps optimize energy consumption.

Functionality and ease of use

EPC12HW offers a range of features to increase convenience and safety. It is equipped with a clear display that shows current temperatures and settings. The ability to work in manual mode allows you to check the pump's operation and adjust it to individual needs. Additionally, the controller has a DHW priority function, which ensures a constant supply of hot water, even during central heating. The "antistop" function protects the installation from stagnation outside the heating season by periodically starting the pump, and the frost protection prevents damage caused by low temperatures. Summer mode limits the operation of the CH pump in warmer months, focusing on providing domestic hot water. An audible alarm warns of excessively high water temperature, increasing safety.

Construction and installation

The EPC12HW controller is characterized by its compact dimensions (155x70x39 mm) and aesthetic appearance. Wall mounting is simple and intuitive. The device has two analog outputs for connecting pumps and integrated CO and DHW temperature sensors. The IP30 protection class provides resistance to dust and moisture, guaranteeing reliable operation in typical operating conditions. The controller is powered by 230V AC 50Hz, which facilitates its integration with the existing electrical installation. The temperature regulator class is I, which confirms its high quality and precision.
