The Heatmiser UH8-N Wiring Centre is designed specifically for use with 12v Heatmiser thermostats, offering a reliable and streamlined wiring solution for underfloor heating systems. It provides control for up to eight zones and includes a dedicated output for a hot water cylinder, making it ideal for both small and large multi-zone installations.
Compatible thermostat models include: NeoStat 12v – Platinum / White / Black
Each zone can accommodate up to 6 actuators, and an optional configuration allows Zone 8 to be set as a radiator zone. In this radiator mode, the pump, valve, and boiler are not triggered — perfect for mixed systems that combine underfloor heating and radiators.
- Radiator Zone Option – Configure Zone 8 as a radiator zone, bypassing UFH pump, valve, and boiler activation for more flexible heating setups.
- DIN Rail Mounting – Easy to install and neatly mountable, thanks to full DIN rail compatibility.
- LED Output Indicators – Provides visual feedback for zone status, boiler, pump, and valve — simplifying system testing and troubleshooting.
- Supports Up to 6 Actuators per Zone – Manage high-demand areas with confidence, with a maximum board load of 5A.
- 230v Actuator Compatible – Works with all standard 230v actuators, including those used across UH4, UH8 and UH8-RF models.
- Simplifies Installation – Typically installed above the UFH manifold for convenient wiring of actuators, pumps, and valves.
The UH8-N helps make wiring underfloor systems faster, cleaner and easier — while offering smart flexibility for mixed heating configurations. For advanced control, pair your 12v thermostats with the neoHub Gen 2 to unlock full app-based smart functionality.
