Heatmiser UH8-N 8 Zone 12V Wiring Centre

The Heatmiser UH8-N is an advanced 8 zone wiring centre designed for use with Heatmiser 12V network thermostats, offering central control over underfloor heating and associated outputs. It enables efficient and organised wiring for up to eight heating zones, with additional outputs to support a domestic hot water cylinder, system boiler, and pump.

• Zones Supported: 8 heating zones (individually controlled)
• Thermostat Compatibility: Compatible exclusively with Heatmiser 12V wired thermostats, typically wired using CAT5 cable
• Actuator Output: 230V AC per zone for valve or actuator control
• Pump and Valve Outputs: Dedicated relay outputs for underfloor heating pump and manifold valve, triggered whenever any zone calls for heat
• Domestic Hot Water Output: Separate output to control a hot water cylinder
• Boiler/Heat Source Control: Volt-free relay for safe and flexible boiler or heat source activation
• Zone 8 Switchable: Can be set as an underfloor heating zone or an isolated radiator zone using the UFH/RAD switch:
  • RAD setting: Zone 8 activates a radiator zone valve and boiler but not the underfloor heating pump/valve
  • UFH setting: Zone 8 behaves as a standard underfloor heating zone
• DIN Rail Mounting: Can be mounted directly to a wall or onto a DIN rail (mounting clips supplied)
• Wiring: All low voltage wiring for thermostats, high voltage for actuators, pumps, valves, and boiler
• Neon Indication: Status feedback for rapid commissioning
• Dimensions: 384 x 148 x 60mm (Length x Height x Depth)
• IP Rating: IP20
• Warranty: 2 Years Manufacturer Warranty

The UH8-N is ideal for installations requiring reliable control and safe integration between underfloor heating zones, radiators, and hot water systems using Heatmiser’s 12V thermostats. It streamlines wiring, ensures centralised management, and offers straightforward installation for both retrofit and new-build projects.
