Hive V4 Wireless Heating Smart Thermostat with Nano 3 Hub OpenTherm 852108
The Hive V4 Wireless Heating Smart Thermostat (MPN 852108) is Hive's full-size smart thermostat for combi boiler systems, supplied complete with the Nano 3 Hub for Wi-Fi connectivity. A bold circular design with a physical large control dial makes manual temperature adjustment effortless, while the full colour touchscreen shows current temperature and schedule at a glance. The Hive app on iOS or Android puts complete heating control in your pocket, supported by voice commands through Alexa, Google Assistant and Apple HomeKit.
New to the V4 generation is OpenTherm compatibility: on supported combi boilers, the heating smart thermostat sends a precise water-temperature demand rather than a blunt on/off signal, allowing the boiler to modulate its output for steadier rooms and Hive's quoted up to 12% extra gas saving over standard relay control. The Ready By self-learning preheat, geolocation alerts, Holiday Mode, Heating History and optional Hive Plus budget tools are all included. Controls heating only — for heating plus a hot water cylinder, see the 852112.
The large rotary dial on the thermostat body lets any household member raise or lower the setpoint immediately without unlocking a phone — a deliberate design choice that keeps everyday use simple.
On compatible combi boilers, OpenTherm sends a digital setpoint rather than a simple on/off signal — the boiler modulates its burner to deliver exactly the water temperature needed. Hive quotes up to 12% extra gas savings vs standard relay control with OpenTherm enabled.
The Ready By function learns how long your home takes to reach the target temperature and fires the boiler early so you're warm when each schedule block begins — and adjusts automatically with the seasons.
Build a personalised weekly schedule via the touchscreen or Hive app. One-tap Boost overrides the schedule and runs heating or hot water for up to 6 hours — then automatically returns to programme.
The Hive app detects when your phone leaves home and sends a push notification if the heating is still on — one tap to turn it off from wherever you are.
Holiday Mode suspends heating (and hot water) for a defined period and restores the schedule automatically on your return date. Frost protection fires the boiler if the temperature drops below 7 °C regardless of any other setting.
View daily and weekly heating usage graphs in the app — see how long the boiler has been running, how quickly the home heats up and cools down, and spot opportunities to save energy.
Works natively with Alexa, Google Assistant and Apple HomeKit for hands-free temperature adjustments and status checks. Siri Shortcuts are also supported.

What is OpenTherm and do I need it?
OpenTherm is a digital communication protocol supported by most modern condensing combi boilers. Instead of simply switching the boiler on or off, the thermostat sends a target water temperature and the boiler modulates its burner to hit it exactly — resulting in steadier room temperatures and Hive's quoted up to 12% gas saving. If your boiler is not OpenTherm-compatible, the receiver operates in standard relay (on/off) mode and full app control still works — modulation just isn't available.
What batteries does it take?
The thermostat runs on 4 × AAA alkaline batteries — all included in the box. Replace all four at the same time using alkaline cells only. Battery life varies with usage but is typically 12–18 months. The receiver (and hub, where supplied) runs on mains power.
Can I control more than one heating zone?
Yes — up to 6 heating zones on an existing multizone system, one Hive thermostat per zone. All zones are managed from the same Hive app. Note: OpenTherm mode is not supported on multi-zone systems — the receiver must be set to standard relay mode on each zone.
What does the Nano 3 Hub do?
The Nano 3 Hub (included in the box) bridges the Zigbee wireless signal between the thermostat/receiver and your home Wi-Fi router. It plugs into a spare Ethernet port on your router and powers from a USB adapter (both supplied). This lets the Hive cloud and app communicate with your thermostat from anywhere.
Does it work on a system boiler?
The 852108 is optimised for combi boilers. For a system boiler or heat-only boiler paired with a hot water cylinder, choose the 852112 Hive V4 Heating & Hot Water thermostat, which includes dedicated hot water scheduling and boost buttons.
