5Model: UH4
Manifold Pump/Valve
Used for an underoor heating manifold pump and or valve.
Connections are clearly marked
L = Live
E = Earth
N = Neutral
When an under-oor heating zone sends a call for heat to the UH4, the
live & neutral output will supply 230v to the manifold pump/valve.
It is recommended that this is fed through a high limit switch placed
on the heating manifold, to protect against mechanical failure of the
manifolds temperature control.
Fuses
Fuse 1. 5amp, 20mm anti-surge fuse, this fuse supplies
power to all 230v outputs from the board it protects the zone,
pump/valve outputs.
