Heatmiser UH4 230V 4 Zone Wiring Centre
The UH4 is an 4 Zone & Hot water wiring centre for use with Heatmiser
230v thermostats.
The UH4 can be used to control any actuator or valve which requires a
230v AC signal. At the same time the UH4 offers the ability to operate a
boiler or other heat source through a volt free output.
An additional output designed for use with underfloor heating
systems, is also included as standard. This is the pump/valve Output,
which would normally operate a manifold pump or a manifold valve.
The H/W output provides a 230v hot water enable signal to the valve,
the auxiliary wires of the valve are wired to the Gr & Or terminals.
Zone 4 can be used as an isolated radiator zone by using the
Yes/No switch.
If the switch is set to NO;
When zone 4 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 YES;
When Zone 4 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.
