The Heatmiser UH8 Wiring Centre is a versatile 8-zone control unit designed for underfloor heating systems. It supports up to eight heating zones and includes two additional time channel connections for hot water control or other auxiliary devices. Each zone can be assigned to one of the two onboard heating time channels, allowing for flexible scheduling.
When any zone calls for heat, the UH8 provides a 230V output to activate the relevant zone actuators, underfloor heating pump, and valve. A volt-free connection is supplied for the boiler, ensuring compatibility with most boiler types. Zone 8 can be configured for radiator control, which bypasses the underfloor heating pump, valve, and boiler activation.
Compatible Thermostats:
DS1 V2 | Slimline-RF | NeoStat V2 White / Black / Platinum | NeoStat WiFi – White / Black | Fastwarm Smart WiFi 2.0 – Black / White

The UH8 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.
- On the back of the UH8, 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 onto the DIN rail from the top.
- Pull the clip down and push the bottom of the UH8 onto the DIN rail.
- Releasing the clip will lock the UH8 in place on the DIN rail.
To remove the UH8, pull both clips down and remove from the DIN rail.
