## Summary description

Engo EPC12HW is a controller designed to manage a central heating (CO) pump and a domestic hot water (CWU) pump. It provides control logic for coordinating pump operation, enabling automatic switching based on system inputs.

## Long description

Engo EPC12HW is a controller designed to manage a central heating (CO) pump and a domestic hot water (CWU) pump. It implements control logic that coordinates the operation of both pumps, enabling automatic switching according to system inputs such as thermostat signals, sensor states, or external control contacts. The device is intended for residential and small commercial heating installations where separate circulation for space heating and hot water is required.
Advantages
The controller provides reliable coordination between the central heating pump and the domestic hot water pump, reducing unwanted simultaneous operation and improving system efficiency. It supports straightforward installation in existing hydraulic systems and offers clear control logic for predictable behavior. The compact design and dedicated functionality simplify wiring and integration with thermostats, timers, or boiler control circuits.
Suitable for
Residential central heating systems with a separate domestic hot water circuit
Small commercial properties requiring coordinated pump control
Retrofitting older installations to provide automatic pump switching
Installations where reliable separation of space heating and hot water circulation is needed
Key specifications
Control targets: central heating pump (CO) and domestic hot water pump (CWU)
Functionality: coordinated automatic switching based on control inputs
Mounting: designed for integration in heating system control panels or DIN-rail / enclosure installation (refer to official installation instructions)
Compatibility: interfaces with standard thermostat contacts and boiler control circuits
Usage environment: residential and small commercial heating installations
How to use
Install Engo EPC12HW according to the manufacturer's wiring diagram and local electrical regulations, connecting the controller to the CO and CWU pump power circuits and to the relevant thermostat or control contacts. Configure control inputs so that the controller receives a clear signal when domestic hot water demand is present and when space heating is required. After wiring, perform a functional test to confirm the correct sequence of pump operation and adjust any timing or interlock settings as specified in the installation guide.
Usage recommendations
Use qualified personnel for electrical installation and commissioning. Verify compatibility with pump power ratings and boiler control logic before connection. Regularly inspect wiring and connections and follow scheduled maintenance for the overall heating system to ensure long-term reliable operation.
