Heating controller Euroster UNI2 — 2 heating circuits, model EUNI2

Euroster UNI2 — 2 heating circuits, model EUNI2 is a compact heating controller designed to manage two independent heating circuits. The unit provides centralized control of temperature setpoints and weekly schedules for each circuit, enabling separate regulation for different zones in a residential or light-commercial installation. Its interface allows setting target temperatures and time programs to coordinate heating cycles and optimize energy use.

Advantages

The controller supports independent control of two circuits, which helps tailor heating to distinct zones and reduce energy waste. Its scheduling capability enables daily and weekly programming, simplifying automated temperature management. Built for straightforward integration, the device can work with common boiler and pump configurations to control heating outputs reliably.

Suitable for

• Homes with two heating zones (e.g., ground and upper floors)
• Small commercial spaces requiring separate temperature control per area
• Retrofit projects where centralized digital control is added to existing boilers and pumps
• Installations that need weekly scheduling and independent circuit regulation

When it may not be suitable

This controller is intended for systems that require control of up to two heating circuits; it is not suitable for installations that need more than two independent circuits or advanced multi-stage boiler management. It also may not meet specific requirements for large commercial HVAC systems that demand complex integrations or proprietary communication protocols.

Key specifications

• Number of independently controlled heating circuits: 2
• Control type: thermostat and time program based regulation for each circuit
• Programmable schedules: daily and weekly time programming per circuit
• User interface: local controls for setting temperatures and programs
• Output capacity: designed to drive standard boiler/zone valve or pump control circuits (verify compatibility with system voltages and loads)
• Mounting: panel or wall mounting compatible with typical HVAC installations
• Power supply: system mains powered (confirm local voltage compatibility)

How to use

Install the controller following local electrical codes and the manufacturer’s wiring diagram, connecting outputs to the boiler, zone valves or circulation pumps as appropriate. Configure the desired temperature setpoints for each circuit and program weekly schedules to match occupancy patterns. Monitor system response and adjust temperature or timing settings to balance comfort and energy use. Regularly check wiring connections and ensure the controller environment is dry and within recommended temperature limits.

What to consider before purchase

• Number of heating zones in your building and whether two circuits are sufficient
• Compatibility with your boiler, valves, pumps and mains voltage
• Required control features such as weekly programming and independent setpoints
• Installation location and wiring route accessibility

Usage recommendations

For optimal performance, pair the Euroster UNI2 controller with appropriately sized circulation pumps and correctly configured zone valves, and use sensible weekly programs that reduce setpoints during unoccupied periods. If integration with advanced building automation or more than two zones is needed, consider a controller designed for expanded functionality.
