Wiring the EPH CONTROLS UFH10 Wiring Centre correctly is essential for your underfloor heating system's performance. Here's a step-by-step guide to help you: Power Supply Wiring: Connect the Live (L), Earth (E), and Neutral (N) wires to the corresponding terminals (230Vac). Programmer Wiring: Connect the Live (L), Earth (E), and Neutral (N) wires from your programmer to the wiring centre terminals for each zone (1-4). Thermostat Wiring (Zones 1-8): Connect the Live supply, Timed switch live from the programmer, Earth, Neutral supply, and Switch live from each thermostat to the wiring centre. Thermostat Wiring (Zones 9 & 10): Similar to zones 1-8, connect the thermostats in zones 9 and 10. Heat Enable Wiring: Connect the Live supply (LS), Earth (E), and Live return (LR) for the Heat Enable function. UFH Pump Wiring: Wire the Live, Earth, and Neutral connections for the underfloor heating pump, ensuring a connection through a high limit thermostat. UFH Valve Wiring: Connect the Grey (GR), Orange (OR), Live (L), Earth (E), and Neutral (N) wires for the UFH valve. Actuator Wiring: For zones 1-8, connect the Live and Neutral supplies to the actuators. For zones 9 & 10, connect Live and Neutral with additional switches. Operation of Zone 9 & 10: Set the switches to UFH for underfloor heating and RAD/HW for radiator/hot water operation, connecting auxiliary contacts for boiler output. Additional Options: Refer to the wiring diagrams for different configurations, including UFH Pump, Valve, Actuators, and Programmer connections. Always consult the EPH CONTROLS UFH10 manual for detailed specifications and safety guidelines. Following these steps will help ensure your underfloor heating system operates efficiently.
