The Heatmiser UH8 underfloor heating wiring centre is designed to work with our 4 channel 230v time clock (TM4) and 230v Set back thermostat (DS-SB) but equally could be used with any 230v room thermostat.

Up to 8 zones can be controlled from the UH8. On board the UH8 are two heating time channels, each zone allows you to specify which time channel it should follow. 2 additional time channel connections are provided for hot water control or other auxiliary devices. On demand from any zone, a 230v output is provided to switch the relevant zone actuator, underfloor heating pump and valve. A volt free connection is supplied for the boiler, making it compatible with almost all types of boilers.

A simple slide switch makes zone 8 suitable for controlling a radiator zone. When used for controlling radiators, zone 8 does not enable the underfloor heating pump, valve and boiler.Up to 4 actuators can be connected to each zone.

• Dimensions (LxHxD) 384x148x60mm

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.

• 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.
