This Heatmiser UH8 Wiring Centre connects internal heating pipework by efficiently centralizing the management of your extensive underfloor system. Specifically, it provides a highly durable and precise transfer of signals from hardwired thermostats to operate up to 8 heating zones and manifold actuators. Furthermore, thanks to its standardized connection layout, you significantly speed up installation by replacing messy junction boxes with a single, secure panel mounted directly on the wall or a DIN rail.
Therefore, this Heatmiser UH8 Wiring Centre works perfectly for modern water-based underfloor heating (UFH) networks in larger homes or commercial properties. Additionally, it easily handles demanding applications, seamlessly combining separate controls for your system boiler, circulation pump, and an optional domestic hot water zone from one compact location.
The unit features a robust construction with clear indicator lights that instantly display the operational status of your system. Moreover, this highly efficient module is powered by 230V and works perfectly with dedicated 230V hardwired thermostats (such as the neoStat series). As a result, this reliable build makes it fully dependable for long-term installations, guaranteeing safe operation under a maximum total load of 5A with IP20 protection.
Key Features & Benefits:
8-Zone Central Management: The system incorporates dedicated inputs for 8 independent heating zones, allowing connection for up to 4 actuators per zone. Consequently, you achieve precise room-by-room temperature management, completely eliminating cable clutter on site.
Radiator Zone Option (Zone 8): The design allows the eighth zone to be separated using a simple slide switch. Ultimately, this allows you to create a highly customizable system where this specific zone controls traditional radiators instead of underfloor heating, entirely without triggering the UFH pump and valve.
Full Boiler & Pump Control: The control centre smoothly transmits a Volt-Free enable signal to the boiler and a 230V supply to the manifold pump and UFH valve whenever any thermostat calls for heat. Importantly, this significantly increases automation and ensures fully safe hydraulic operation.
Comprehensive Hot Water Management: The unit features built-in capabilities for dedicated hot water control. For example, this allows you to seamlessly integrate your hot water cylinder with the overall heating system logic.
Safe & Simple Installation: The module is supplied with the ability to be conveniently screwed to the wall or installed on a standard DIN rail using the included back clips. Besides that, the internal circuits and 230V outputs are effectively protected by a built-in 5A surge fuse.
