Wireless Control Hub for Multi-Zone Underfloor Heating
Heatmiser Smart Wiring Solution with Built-In RF Capability
The Heatmiser UH8-RF is an advanced wireless wiring centre designed to manage up to 8 underfloor heating zones via RF thermostats such as the Slimline-RF, Touch-RF, and neoAir. Perfectly suited for installation near your manifold, this unit centralises control while removing the need for extensive cabling.
It enables both local and remote activation of actuators, pumps, and valves—streamlining underfloor heating system installations in homes or commercial spaces. A 230v output is triggered when any thermostat calls for heat, activating the appropriate zone valve and circulating pump. A separate volt-free output is provided for boiler control, ensuring broad compatibility with modern and traditional boiler systems.
The UH8-RF also supports wireless communication with the Heatmiser RF Switch, creating a fully wireless solution for boiler activation—ideal when wiring access is limited or costly.

Heatmiser UH8-RF
The Heatmiser UH8-RF is our 8 Zone wireless wiring centre designed to work with our Slimline-RF, Touch-RF and neoAir Thermostats.
The UH8-RF provides central switching and is therefore ideally situated next to the underfloor heating manifold. 8 zones can be controlled as well as providing an output for a hot water cylinder. On demand from any zone, a 230v output is provided to switch the relevant zone actuators, unde
rfloor heating pump and valve. A volt free connection is supplied for the boiler, making it compatible with almost all types of boilers. The boiler
signal can also be sent via RF to the RF Switch, providing the installer a totally wireless solution.
Up to 6 actuators can be connected to each zone. An external aerial is available for use when the UH8-RF is being mounted in a metal cupboard
or when the wireless signal is restricted.
A software option in the thermostat allows you to configure which zones are underfloor heating and which zones are radiators. Radiator zones
will not enable the underfloor heating pump, valve and boiler when there is a call for heat. Radiator zones will not enable the underfloor heating pump,
valve and boiler when there is a call for heat. Radiator zones should enable the boiler from the end switch of the valve.
