12v Network Thermostat Wiring Centre (UH1) - Shop Link The UH1 is designed to be used with our 12v Network thermostats. The UH1 provides central switching and is therefore ideally situated next to the underfloor heating manifold. 8 Zones can be controlled as well as providing an output for a hot water cylinder. On demand from any zone, a 230v output is provided to switch the relevant zone actuators, underfloor heating pump and valve. A volt free connection is supplied for the boiler, making it compatible with almost all types of boilers. Up to 6 actuators can be connected to each zone An option is provided to turn zone 8 into a radiator zone. In this mode the Underfloor heating pump, valve and boiler are not enabled when there is a call for heat from zone 8. The UH1 provides a network power allowing connection to our network products, including the central Touchpad, Netmonitor and PCLink.
230V 4 Zone Wiring Wiring Centre (UH2) - Shop Link The UH2 can be used in conjunction with our mains thermostats. The UH2 provides central switching of up to 4 zone actuators as well as providing an output for a hot water cylinder and the heating system boiler and pump. When used for underfloor heating, an option is available to use zone 4 for conventional radiator control. Up to 6 actuators can be connected to each zone.
230V 8 Zone Wiring Centre (UH3) - Shop Link The UH3 is designed to work with our 4 channel 230v time clock (TM4) and Set Back thermostat (DS-SB) but equally could be used with any 230v room thermostat. 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 channels connections are provided for hot water control or other auxillary 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. A slide switch makes zone 8 suitable for controlling a radiator zone, in which case the heating pump, valve and boiler are not enabled.
