Heatmiser UH8

The Heatmiser UH8 can be used in conjunction with our mains thermostats. The UH8 provides central switching of up to 8 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 8 as a conventional radiator zone. Up to 6 actuators can be connected to each zone.

Radiator Option An option is provided on the  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.

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.

Output Indication The UH8 provides LED indication of the zone, boiler, pump and valve status providing the installer an easy method of testing the heating system.
