The Heatmiser UH8-RF Wiring Centre is our 8-zone wireless wiring centre designed specifically to work with the Slimline-RF and NeoAir thermostats: NeoAir V3 Black / Platinum / White
Providing central switching, the UH8-RF is ideally located near the underfloor heating manifold for easy wiring and control. It manages up to 8 zones and includes a dedicated output for a domestic hot water cylinder. When any zone calls for heat, the wiring centre activates the appropriate 230V zone actuators, underfloor heating pump, and valve. The boiler connection is volt-free, making it compatible with most boiler types. Alternatively, the boiler signal can be transmitted wirelessly via RF to the optional RF Switch, enabling a fully wireless system installation.
Each zone supports up to 6 actuators. For challenging installations, an external aerial is available to boost signal strength when the UH8-RF is installed inside a metal cupboard or where wireless signals may be limited.
The thermostat software includes an option to configure zones as either underfloor heating or radiator zones. Radiator zones bypass the underfloor heating pump, valve, and boiler when there is a heat demand, and instead activate the boiler via the end switch of the valve.
- Central control for up to 8 zones – Flexible multi-zone heating management from a single wiring centre.
- 230V actuator outputs – Supports up to 6 actuators per zone, managing heating elements efficiently.
- Volt-free boiler connection – Compatible with nearly all boiler types and supports wireless boiler control via the RF Switch (optional).
- Output for domestic hot water cylinder – Integrates hot water management alongside heating zones.
- Radiator zone option – Configurable zones that exclude UFH pump and valve activation, ideal for mixed heating systems.
- Wireless fail-safe function – Ensures the system defaults to a safe state if wireless communication is lost.
- DIN rail mounting option – For tidy, professional installation (DIN rail not included).
- External aerial available – Improves wireless reception in difficult locations.
- Compact dimensions – 384x148x60mm (LxHxD), suitable for mounting near manifolds or in control cabinets.
The UH8-RF Wiring Centre can be extended with the RF Switch for full wireless boiler control. For different sizes of 12V systems, consider our alternative wiring centres like the UH8-N, UH8, and UH4, or the Fastwarm 10-Zone Wiring Centre for a non-Heatmiser alternative.
The UH8-RF can be mounted directly to a wall using four screws or alternatively, the unit can be DIN rail mounted.
When DIN Rail mounting, you first need to insert the two clips provided on the back of the UH8-RF.
- On the back of the UH8-RF, position the clip in the middle and slide down.
- Points A and B locate in the corresponding holes and lock into place.
- Locate the UH8-RF onto the DIN rail from the top.
- Pull the clip down and push the bottom of the UH8-RF onto the DIN rail.
- Releasing the clip will lock the UH8-RF in place on the DIN rail.
To remove the UH8-RF, pull both clips down and remove from the DIN rail.
