Wiring Centre 2 3 Model: UH8
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 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.
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.
