Boiler Pump Controller Engo EPC11W — controller for central heating (CO) or domestic hot water (CWU), model EPC11W

Engo EPC11W is a compact pump controller for central heating (CO) or domestic hot water (CWU) circulation pumps. The unit automatically starts and stops the pump based on boiler signals, simplifies integration with residential and small commercial heating systems, and provides basic protections such as dry-run prevention. Designed for inline installation close to the boiler, the controller supports reliable pump operation without the need for manual intervention.

Advantages

The controller offers automatic control that responds to the boiler's operating status, reducing unnecessary pump operation and improving system efficiency. It includes dry-run protection to prevent damage when there is no fluid flow, and a straightforward electrical interface for easy connection to standard boilers and circulation pumps. The device's compact design allows installation in tight spaces near the boiler and makes it suitable for retrofits and new installations.

Suitable for

• Controlling a central heating (CO) circulation pump
• Controlling a domestic hot water (CWU) circulation pump
• Residential boilers and small commercial heating systems
• Retrofit projects where simple pump automation is required

Key specifications

• Function: Automatic pump control based on boiler signal for CO or CWU circuits
• Protection: Dry-run protection to prevent pump damage when no flow is detected
• Installation: Compact enclosure suitable for mounting near the boiler
• Compatibility: Designed to interface with standard boiler control outputs and circulation pumps
• Application: Intended for residential and small commercial heating installations

How to use

Install the Engo EPC11W close to the boiler and connect the controller to the boiler control output and to the circulation pump according to the wiring diagram provided by the manufacturer. When the boiler signals heat demand, the controller will supply power to the pump; when the boiler stops or reaches the set conditions, the controller will stop the pump. Ensure electrical connections are made with the power off and comply with local regulations. Commission the system by verifying that the pump starts and stops in response to the boiler and that dry-run protection operates if circulation is interrupted.

Usage recommendations

Use the controller in systems with a compatible boiler output and a properly sized circulation pump. For safe and reliable operation, combine the controller with regular system maintenance, appropriate pipework, and correct pump selection. If unsure about wiring or compatibility, consult a qualified heating technician or electrician.
