The Heatmiser UH1-W is our wireless central wiring switch box designed to be used with our slimline wireless thermostats. The UH1 offers the following functionality;

The Heatmiser UH1-W is designed to be used in conjunction with our slimline wireless thermostats. The UH1-W 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 external aerial is available for use when the UH1-W is being mounted in a metal cupboard or when the wireless signal is restricted.

A software option in the thermostat allows you to configure which zones are underfloor heating and which zones are radiators. Radiator zones will not enable the underfloor heating pump, valve and boiler when there is a call for heat. Radiator zones should enable the boiler from the end switch of the valve.

• Central wiring to up to 8 zone actuators
• Output for under-floor heating valve and pump activated when any thermostat calls for heat
• Wireless Fail Safe Function
• Works with our slimline wireless thermostats.
• Output for a multiple radiator zones
• Output for domestic hot water
• Low voltage wiring to thermostats.
• Actuator outputs: 240V

Please note: This is not compatible with the Touchscreen Wireless Thermostats
