Heatmiser UH8 230V 8 Zone Wiring Centre

Heatmiser UH8 230V 8 Zone Wiring Centre

The UH8 is an 8 Zone wiring centre for use with Heatmiser 230v thermostats.
The UH8 can be used to control any actuator or valve which requires a 230v AC signal to open. For mid position valves and those requiring a closing signal, a changeover relay is required. At the same time the UH8 offers the ability to operate a boiler or other heat source through
a volt free output.
Additional outputs designed for use with underfloor heating systems are also included as standard. These are the pump and valve outputs which would normally operate a manifold pump or a manifold valve. Zone 8 can be used as an isolated radiator zone by using the UFH/RAD switch.

If the switch is set to RAD;
When zone 8 calls for heat this will provide an output to a radiator zone valve and the boiler, but WILL NOT enable the underfloor heating pump/valve output.

If the switch is set to UFH;
When Zone 8 calls for heat, this will act as an underfloor heating zone, by enabling the actuator, boiler and pump/valve outputs. Any output which is not needed can be ignored.
