Emmeti U9380004 (EWC4) 4-Way Wiring Centre

The Emmeti EWC-4 is a compact and robust 4-way wiring centre designed for efficient, centralised control of small-scale Underfloor Heating (UFH) and Wall Hung Radiator (WHR) systems.

This 230V unit simplifies the electrical connection of all system components, making installation and maintenance straightforward for up to four independent heating zones.

Key Features & Benefits

• 4 Zone Control: Allows central connection and control for up to four individual room thermostats and their corresponding electrothermic actuators/heads.
• Boiler & Pump Interlock: Features independent relays for the boiler (volt-free terminals) and manifold circulating pump (230V output), ensuring they are only activated when at least one zone calls for heat. This maximises energy efficiency.
• LED Indication: Clear LED lights on the unit's face provide immediate visual status of system operation:
  • Power On (Green)
  • Boiler On (Red)
  • Pump On (Red)
• External Time Switch/Programmer Input: Includes dedicated terminals for connecting a central time switch or programmer, enabling global time control and Night Setback operation across all four zones for further energy savings.
• Actuator Capacity: Each of the four channels can connect up to three 230V electrothermic actuators (underfloor heating heads).
• Ease of Installation: Designed with clearly marked terminals and ample wiring space to ensure quick, reliable connection of all components.
• Safety: Equipped with a 4A time-delayed fuse and housed in a self-extinguishing ABS case (IP30 rated).
