The Heatmiser UH8 is designed to work with our 4 channel 230v time clock (TM4) and 230v Set Back thermostat (DS-SB) but equally could be used with any 230v room thermostat. Up to 8 zones can be controlled from the UH8. On board the UH8 are two heating channels, each allows you to specify which time channel it should follow. 2 additional time channel connections are provided for hot water control or other auxiliary devices.

On demand from any zone, a 230v output is provided to switch the relevant zone actuator, underfloor heating pump and valve. A volt free connection is supplied for the boiler, making it compatible with almost all types of boilers.

A simple slide switch makes zone 8 suitable for controlling a radiator zone. When used for controlling radiators, zone 8 does not enable the underfloor heating pump, valve and boiler. Up to 4 actuators can be connected to each zone.

In addition, the UH8 offers DIN Rail Mounting and the enclosure has been designed so that you no longer need to drill cut outs for cable entry.

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.
