Up to 8 zones can be controlled from the UH3. On board the UH3 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.
