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.

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.
