Heatmiser UH8-RF V2 - 8 Zone Wireless Wiring Centre v2

The Heatmiser UH8-RF v2 is an advanced 8-zone wireless wiring centre, purpose-built for use with Heatmiser RF thermostats such as the Slimline-RF v3 and neoAir v3. It is designed to provide centralised switching for both underfloor heating and radiator systems, making it ideal for multi-zone smart home or commercial heating installations.

• Zones: Controls up to 8 heating zones; each channel configurable for underfloor heating or radiator circuits
• Output for Hot Water Cylinder: Dedicated output for hot water cylinder control, plus additional outputs for pump and valve activation
• Actuators: Connect up to 6 actuators per zone (230V AC)
• Boiler/Heat Source Control: Volt-free relay output for boiler or heat source activation, supporting both heat on and heat off signals; compatible with most domestic boilers
• Wireless Boiler Link: Can send a radio signal to the RF Switch v2 for completely wireless installation when direct wiring to the boiler is not possible
• DIN Rail Mounting Option: Yes (DIN rail not included)
• External Aerial Option: Available for installations with challenging wireless environments (e.g. metal enclosures)
• Pump and Valve Outputs: Activates underfloor heating pump and manifold valve when any relevant thermostat calls for heat
• Test Switches: Onboard test switches for easy installation and commissioning
• Additional Features: Creepage protection, pump delay, and wireless fail-safe function
• Power Supply: 230V AC
• Relay Load Max: 3A per relay; total load 5A
• IP Rating: IP20
• Dimensions: 384 x 148 x 60mm (L x H x D)

Each zone can be set as either underfloor heating or radiator. Zones set for radiators do not activate the underfloor heating pump, valve, or boiler directly, allowing tailored performance and system protection. The system also features neon indicators for status feedback and is compatible with RF Boosters to extend wireless range where required.
