## Summary description

Euroster EFH2 is a heating control module designed for management of two independent heating circuits with a dedicated boiler output. The unit provides control signals for zone valves or pumps, enables boiler activation, and integrates into residential or small commercial heating systems to automate temperature zones and improve system responsiveness.

## Long description

Euroster EFH2 — 2 heating circuits with boiler output is a compact heating control module designed to manage two independent heating circuits and provide a dedicated boiler activation output. The unit supplies control signals for zone valves or circulation pumps and coordinates boiler operation to match demand from each zone. It is intended for residential and small commercial installations where simple zoning and reliable boiler switching are required.
Advantages
The Euroster EFH2 offers simultaneous management of two separate heating circuits with clear control for each zone and a dedicated boiler output for efficient system coordination. Its straightforward functionality simplifies integration with existing pumps and zone valves, reducing installation complexity. The module improves the responsiveness of multi‑zone systems by centralizing activation logic for both circuits and the boiler.
Suitable for
Two‑zone heating systems in apartments, houses, or small commercial premises
Setups using zone valves or circulation pumps per heating circuit
Systems requiring a separate boiler activation output to control burner or boiler relay
Retrofit projects where a compact control module is preferred
When it may not be suitable
The EFH2 is not designed to replace full-featured supervisory controllers or building management systems that require advanced scheduling, weather compensation, or remote connectivity. It also does not provide integrated room thermostats or wireless controls; external thermostats or actuators are required for zone temperature regulation.
Key specifications
Control capacity: two independent heating circuits
Boiler output: dedicated output for boiler activation
Control outputs: outputs suitable for driving zone valves or circulation pumps
Intended application: residential and small commercial heating systems
How to use
Install the Euroster EFH2 in a location that allows secure wiring to zone actuators, pumps and the boiler control input. Connect each heating circuit output to its corresponding zone valve or pump, and wire the boiler output to the boiler's control relay according to the manufacturer's wiring diagram. Use external room or zone thermostats to call for heat; the module will route calls from each zone to the appropriate actuator and activate the boiler when any zone demands heat. Verify all electrical connections and test each zone and boiler activation cycle before leaving the system in operation.
What to consider before purchase
Compatibility with existing zone valves, pumps and boiler control inputs
Number of zones required—EFH2 supports two heating circuits only
Need for external thermostats or controllers to provide temperature setpoints
Electrical supply and mounting space available at the installation site
Usage recommendations
For reliable operation, pair the Euroster EFH2 with compatible zone actuators and ensure the boiler control input supports the module's switching type. Perform a test sequence after installation to confirm correct sequencing of zone activation and boiler firing. If more advanced scheduling or remote monitoring is required, consider integrating EFH2 with additional control equipment or selecting a controller with those features.
