UFH4ZW – Installation Manual
Description
The UFH4ZW isan4 Zone & Hot water wiring centre for use with Polypipe
230v thermostats.
The UFH4ZW 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
UFH4ZW oers the ability to operate a boiler or other heat source through
a volt free output.
An additional output designed for use with underoor 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 underoor heating
pump/valve output.
If the switch is set to YES;
When Zone 4 calls for heat, this will act as an underoor heating zone,
by enabling the actuator, boiler and pump/valve outputs.
Any output which is not needed can be ignored.

Installation
The UFH4ZW can be mounted directly to a wall using four screws or
alternatively, the unit can be DIN rail mounted.
WhenDIN Rail mounting, you rst need to insert the two clips
provided on the back of the UH4, as shown in the image;
• On the back of the UFH4ZW, position the clip in the middle
and slide down.
• Points A and B locate in the corresponding holes and
lockinto place.
• Locate the UFH4ZW onto the DIN rail from the top.
• Pull the clip down and push the bottom of the UFH4ZW onto
the DIN rail.
• Releasing the clip will lock the UFH4ZW in place on the DIN rail.
To remove the UFH4ZW, pull both clips down and remove from the DIN rail.

H/W
This output is used to control a hot water valve via a cylinder
thermostat
L = Live
E = Earth
N = Neutral
Gr = Grey
Or = Orange
The auxiliary wires of the valve, usually grey & orange, are wired to the
Gr & Or terminals.
Zones 1…4
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.
Connections
Mains Supply
Power supply into the UFH4ZW 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.

Manifold Pump/Valve
Connections are clearly marked
L =Live
E =Earth
N = Neutral
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, 20mmanti-surge fuse, thisfuse supplies
power to all 230v outputs from the board itprotects the zone,
pump/valve outputs.
Used for an underoor heating manifold pump and or valve.
When an under-oor heating zone sends a call for heat to the UFH4ZW,
