Heatmiser UH8-N Wiring Centre: 8 zones for 12V thermostats (video guide)

The Heatmiser UH8-N is an eight zone wiring centre made for 12V thermostats such as the neoStat 12V. It runs from 230V and powers the thermostats itself, and when any zone calls it enables the pump, valve and boiler.

Here are the key facts, with the data sheet and install manual to download below.

Adding a neoStat-HW hot water timer

The UH8-N's hot water zone is switched over its 12V terminals by a neoStat-12v in timer mode. A Heatmiser neoStat-HW takes a mains supply, so it must never go on those terminals. It is wired on its own, straight to the hot water valve through the cylinder thermostat, and the valve's end switch brings the boiler on. Our step by step video shows exactly how.
