Heatmiser UH8-RF Mini 8 Zone Wireless Wiring Centre - Compact RF Underfloor Heating Control Unit

Description

The Heatmiser UH8-RF Mini is a compact central control unit designed for wireless underfloor heating and radiator systems, supporting up to 8 zones with radio frequency connectivity to Heatmiser RF thermostats such as the Slimline-RF and neoStat-RF. It provides central switching for actuators, underfloor heating pumps and valves, with a wireless link to the boiler via the RF Switch.

A Neostat mode enables automatic thermostat pairing for faster commissioning, and the compact DIN rail-mountable design keeps installation tidy within electrical enclosures. It's a flexible option for residential heating systems that need multi-zone control without extensive additional wiring.

Automatic Pairing with Neostat Mode

Neostat mode enables automatic thermostat pairing, simplifying setup and reducing commissioning time compared with manual zone-by-zone configuration.

Qualified Installation Required

This is a mains-voltage (230V AC) wireless wiring centre. Installation must be carried out by a qualified heating engineer, mounted in an accessible location, in accordance with current UK wiring regulations.

RF Range Considerations

Quoted RF range is up to 100m in open space; actual range indoors will be reduced by walls, floors and metal enclosures. Pair with an RF Switch for boiler control where a direct wired connection isn't practical.

8-Zone Wireless Control

Manage up to 8 heating zones independently via RF link to compatible Heatmiser thermostats.

Automatic Thermostat Pairing

Neostat mode provides automatic pairing for straightforward, faster installation.

Volt-Free Boiler & Pump Relays

Volt-free outputs for heat source and circulation pump support wide boiler compatibility.

Dedicated Hot Water Output

A dedicated hot water cylinder output keeps DHW control separate from space heating zones.

Compact DIN Rail Design

A space-saving footprint suited to installation within standard electrical enclosures.

Long Wireless Range

Up to 100m RF range in open space, supporting flexible thermostat placement around the property.

How many zones can the UH8-RF Mini control?

It controls up to 8 heating zones wirelessly, plus a dedicated hot water cylinder output.

What is Neostat mode?

Neostat mode enables automatic pairing between the wiring centre and compatible thermostats, simplifying and speeding up installation.

How many actuators can I connect per zone?

Each zone supports up to 4 actuators, within an overall 8A maximum total actuator load.

What is the effective wireless range?

Up to 100m in open space, though indoor range will be reduced by walls, floors and any metal enclosures the unit is mounted in.

Can this unit control the boiler wirelessly?

The UH8-RF Mini provides a volt-free boiler relay for wired connection, and can be paired with an RF Switch for boiler control where direct wiring to the boiler isn't practical.
