UH8 – Installation Manual

Description

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. At the same time the UH8 oers the ability to operate a

boiler or other heat source through a volt free output.

Additional outputs designed for use with underoor 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 underoor

heating pump/valve output.

If the switch is set to UFH;

When Zone 8 calls for heat, this will act as an underoor heating zone,

by enabling the actuator, boiler and pump/valve outputs.

Any output which is not needed can be ignored.

Installation

The UH8 can be mounted directly to a wall using four screws or

alternatively, the unit can be DIN rail mounted.

When DIN Rail mounting, you first need to insert the two clips

provided on the back of the UH8, as shown in the image;

• On the back of the UH8, position the clip in the middle

and slide down.

• Points A and B locate in the corresponding holes and

lock into place.

• Locate the UH8 onto the DIN rail from the top.

• Pull the clip down and push the bottom of the UH8 onto

the DIN rail.

• Releasing the clip will lock the UH8 in place on the DIN rail.

To remove the UH8, pull both clips down and remove from the DIN rail.

Insert clip here.

Then Slide down to lock in place.

Wiring Centre4 5Model: UH8

Zones 1…8

Zones outputs are clearly marked

L = live out to actuator or valve

N = neutral to actuator or valve

There are two connections live (L) and neutral (N), both terminals

marked L are the same and both terminals marked N are the same.

Each zone output corresponds to the thermostat wired in at the

top of the pcb.

UFH Pump

Used for an underoor heating manifold pump.

Connections are clearly marked

L = Live

E = Earth

N = Neutral

When an under-oor heating zone sends a call for heat to the UH8, the

live & neutral output will supply 230v to the manifold pump.

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.

UFH Valve

Used for an underoor heating manifold valve.

Connections are clearly marked;

Gr = Grey

Or = Orange

L = Live

E = Earth

N = Neutral

When an under-oor heating zone sends a call for heat to the UH8,

the live & neutral output will supply 230v to the manifold valve.

The auxiliary wires of the valve, usually grey & orange, are wired to the

Gr & Or terminals.

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.

Connections

Mains Supply

Power supply into the UH4 which should be fused at 5 amps these

connections are marked

L = live or phase 230v AC 50/60Hz

N = Neutral

E = Earth

Heat Enable

This is the main call for heat for the system, there are 3 connections;

LS = Live Supply

E = Earth

LR = Live Return

Electrically this is a volt free switch, whatever supply is placed on the

LS connection, is fed to the LR connection when there is a call for heat.
