Underfloor Heating & Radiator Wiring Centres from Heatmiser

Central Wiring Switch Boxes

Our central wiring switch boxes have been designed to simplify the wiring process. Using our wiring centres in your application means that the actuator, boiler and pump connections are wired from a single point.

Heatmiser UH8-N

The Heatmiser UH8-N is designed to be used in conjunction with our 12v Network thermostats. The UH8-N provides central switching and is therefore ideally situated next to the underfloor heating manifold.

Eight 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, underfloor heating pump and valve. A volt free connection is supplied for boiler making it compatible with almost all boilers. Up to 6 actuators can be connected to each zone. An option is provided to turn the zone 8 into a radiator zone. In this mode the underfloor heating pump, valve and boiler are not enabled when there is a call for heat from zone 8.

Heatmiser UH4

The Heatmiser UH4 can be used in conjunction with our mains thermostats. The UH4 provides central switching of up to 4 zones actuators as well as providing an output for a hot water cylinder, the system boiler and pump.

When used for underfloor heating, an option is available to use zone 4 as a conventional radiator zone. Up to 6 actuators can be connected to each zone.

The Heatmiser UH8-RF is designed to be used in conjunction with our wireless thermostats. The UH8-RF provides central switching and is therefore ideally situated next to the underfloor heating manifold. Eight 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, underfloor heating pump and valve. A volt free connection is supplied for the boiler, making it compatible with almost all types of boilers. Up to 6 actuators can be connected to each zone. A software option in our wireless thermostats allows you to configure which zones are underfloor heating and which are radiators. The RF Switch can be paired to the UH8-RF in order to offer a wireless boiler link.

Headline Features

Radiator Option
An option is provided on the UH8-N, UH4 and UH8 for a radiator zone to be controlled. When enabled, the last zone is setup for a radiator zone and therefore doesn’t enable the UFH pump, valve or boiler. On the UH8-RF this option is available per zone.
DIN Rail Mounting
All of our wiring centres offer DIN Rail Mounting.
Output Indication
All of our wiring centres provide LED indication of the zone, boiler, pump and valve status providing the installer an easy method of testing the heating system.

Easy Installation
The Heatmiser Wiring Centres offer an easy way of installing your underfloor heating system. The wiring centre is usually situated above the UFH manifold allowing easy connections to the actuators, UFH pump and valve.
230v Actuators
All wiring centres work with 230v actuators and up to 6 actuators can be connected to each zone up to a total board maximum of 5A.
RF Connection
The UH8-RF offers a wireless connection to our wireless thermostats. In addition, the RF Switch can be used to provide a wireless link to the boiler.
