Baxi uSense 2 Wired Smart Room Thermostat

Baxi uSense 2 Wired Smart Room Thermostat

The Baxi uSense 2 Wired Smart Room Thermostat (MPN 7775937) is a modern, app-connected heating control built to work natively with Baxi combi boilers and Baxi air source heat pumps. It supports OpenTherm modulating control, RBUS connection and a standard 230 V switched-live output, so it slots into virtually any Baxi system — directly or via the optional Gateway & Power Adapter Kit (MPN 7822453) for legacy and heat-pump installations.

Pair the unit with the free Baxi Thermostat app on iOS and Android to set a 7-day schedule, monitor your energy use, switch on holiday mode, and adjust your home from anywhere. When wired by OpenTherm or RBUS on a compatible combi, the uSense 2 is Boiler Plus compliant out of the box — meeting current Building Regulations without an extra control device.

Key features

App control from anywhere

Full remote control via the free Baxi Thermostat app on iOS and Android — adjust temperature, override the schedule and check status from anywhere with an internet connection.

7-day adaptive schedule

Set a different schedule for every day of the week, with multiple comfort periods per day, so the home is warm when it needs to be and energy isn't wasted when it doesn't.

Modulating OpenTherm control

OpenTherm tells the boiler exactly how hard to fire and at what flow temperature — smoother, more efficient running than simple on/off. RBUS connection unlocks the same on Baxi-native systems.

Holiday mode saves money

Drop the home to a low frost-protect set-point while you are away, then automatically restore your normal schedule on the day you return — no fiddling, no wasted heat.

Energy monitoring built-in

Track your heating and hot water usage directly in the app, so you can see the impact of schedule and set-point changes on your running costs.

Outdoor weather compensation ready

Connect a Baxi outdoor sensor (OpenTherm installations) for true weather-compensated control. The heating curve is then adjusted via the uSense 2 app.

Multi-zone capable

For zoned systems, install one uSense 2 plus one Gateway & Power Adapter Kit per zone — independent control of each part of the home.

Wired reliability

Hard-wired connection means no batteries to change and no wireless dropouts. Maximum 50 m cable run between the room unit and the gateway / appliance.

Do you also need the Gateway & Power Adapter Kit (7822453)? It depends on the appliance — see the compatibility table below. The newer Baxi 200 / 400 / 600 / 800 Combi 2 ranges and the Assure 500 Combi 2 connect directly (no gateway needed). Heat pumps and older combis usually need the gateway.

Frequently asked questions

Can I install the uSense 2 myself?
No. Although the room unit itself uses low-voltage wiring, the gateway side connects to mains 230 V and must only be installed by a qualified heating engineer or electrician. Incorrect wiring will damage the room unit and gateway and may invalidate your boiler / heat pump warranty.
Does it work with my older Baxi or Potterton combi?
Yes — combined with the Gateway & Power Adapter Kit (7822453). The newer Baxi Combi 2 and Assure 500 Combi 2 ranges connect directly without the gateway, but earlier combis route through the gateway for their OpenTherm or 230 V switched-live link.
Will it work on a system or heat-only boiler?
No. Per Baxi's installation guide the uSense 2 is not compatible with System or Heat-Only boilers, with or without the gateway. For those systems Baxi recommends an alternative programmer / thermostat from their controls range.
How does it satisfy Boiler Plus?
Boiler Plus requires combi installations to include one of four energy-saving measures. When connected by OpenTherm or RBUS, the uSense 2 provides modulating load and weather compensation, which satisfies the requirement on its own.
Can I run multiple zones?
Yes — install one uSense 2 plus one Gateway & Power Adapter Kit per zone. Each thermostat appears as a separate zone in the Baxi Thermostat app.
How do I activate the warranty?
Register the thermostat at baxiworks.co.uk at the time of installation. Registered units receive a 2-year parts warranty; unregistered units fall back to a basic 12-month warranty.
Need the gateway too?
For heat pumps and older Baxi / Potterton / Main combis, also order the Baxi uSense 2 Gateway & Power Adapter Kit (MPN 7822453) alongside this thermostat.
