Pack of 4 Smart Radiator Thermostats Replaces Standard TRVs Room-by-Room Control 6 Adapters Per Unit Included App + Alexa + Google + HomeKit Add-On — Requires tado° Starter Kit
The tado° Smart Radiator Thermostat V3+ Quattro Pack contains four smart TRV heads that replace your existing thermostatic radiator valves, giving you precise, individual temperature scheduling and control for four rooms or radiator zones — all managed from the tado° app, and all working together intelligently with your existing tado° Starter Kit. Each unit includes six valve adapters for compatibility with virtually all standard UK radiator valves. Stop heating rooms that aren't in use, wake up to a warm bedroom without heating the whole house, and let your office cool down once you've finished working — all automatically, all from your phone, and all working in harmony with your boiler control. Save up to 28% on your heating bills, as verified by the independent Fraunhofer Institute.
⚠️ Important — These Are Add-On Devices
The tado° Smart Radiator Thermostat Quattro Pack is an add-on product. It requires an existing tado° V3+ Starter Kit (any version — Wired, Wireless, or Smart Radiator Thermostat Starter Kit) already installed and working in your home. The Internet Bridge included in your Starter Kit provides the wireless connection for these units — no additional bridge is needed. If you do not yet have a tado° Starter Kit, purchase one first and then add these units. These devices are not compatible with tado° X products or bridges.
Why Upgrade Your Radiators with tado° Smart TRVs?
A standard room thermostat — even a smart one — controls your boiler centrally: when the main thermostat reaches its setpoint, the boiler stops, and every radiator in the house cools down together. That's wasteful in most homes, where different rooms have different usage patterns and different heat retention. The bedroom doesn't need to be warm all day. The bathroom only needs heat in the morning. The home office heats up quickly and cools slowly due to computer heat. The tado° Smart Radiator Thermostats solve this by giving each radiator — and therefore each room — its own independent temperature schedule and setpoint, managed intelligently alongside the central boiler control.
Universal Valve Compatibility — 6 Adapters Included Per Unit
Each Smart Radiator Thermostat in this pack comes with six valve adapters, covering virtually all standard UK and European thermostatic radiator valve bodies. The thermostat body itself connects via the universal M30 × 1.5mm thread — the most common TRV connection thread in the UK. The adapters allow it to fit on top of valve bodies from all major manufacturers where the thread differs from M30 × 1.5mm.
The tado° app's compatibility checker covers thousands of specific radiator valve makes and models, identifying which adapter to use and guiding you step-by-step through the fitting process — including the correct pin configuration for your valve. No specialist tools are required; the unit simply unscrews from the old TRV head and the tado° head screws or clips on in its place. No water is drained, no pipework is disturbed, and there is no risk of water leaks during installation.

🔍 Check Before You Buy
Use the tado° Compatibility Checker at tado.com to confirm that the Smart Radiator Thermostat V3+ is compatible with your specific radiator valve model before purchasing. Enter your valve brand and model (often printed on the valve body or available from the installer's paperwork) and the checker will confirm compatibility and identify the correct adapter. Compatibility covers the vast majority of standard UK TRV valve bodies.
How tado° Multi-Room Control Works
When Smart Radiator Thermostats are added to a tado° Starter Kit setup, the system becomes genuinely intelligent at the whole-home level. Here's how the heating logic works:
- Each Smart Radiator Thermostat continuously measures the temperature in its room and compares it to the scheduled setpoint for that room at that time of day.
- If a room is below its setpoint, the Smart Radiator Thermostat opens its valve and signals the tado° system that heat is needed. The tado° Starter Kit (your room thermostat or receiver) then calls the boiler to fire.
- When a room reaches its setpoint, its valve closes. When all rooms have reached their setpoints, the boiler call is released and the boiler stops — no energy is wasted maintaining a temperature that's already been achieved.
- Rooms that are scheduled to be at their minimum away temperature (e.g. 15°C) simply don't call for heat until the next heating period begins, even if the rest of the house is being heated.
✅ Boiler Efficiency Note
For the best efficiency with Smart Radiator Thermostats, tado° recommends fitting them in all heated rooms — not just some. When some radiators are controlled by old manual TRVs and others by tado° Smart units, the old manual TRVs may restrict flow to warmer rooms while tado°-controlled rooms correctly call for heat, creating a mismatch. Full coverage allows tado° to properly orchestrate the whole heating system. With this Quattro Pack covering four rooms, consider how many more radiators in your home would benefit from smart control and whether additional packs are needed.
Installation — Typically 5–20 Minutes Per Radiator
The tado° Smart Radiator Thermostat is designed for DIY installation with no plumbing knowledge required. Crucially, no water draining is needed — the TRV head is separated from the valve body by a separate pin mechanism, meaning the valve body itself (which contains water) is never disturbed. You simply remove the old TRV head and fit the tado° head in its place.
The tado° app guides the installation process step by step for each unit, including a calibration sequence that the thermostat runs automatically when first powered on — it opens and closes the valve to measure its full travel range and set its zero position. The QR code on each unit's packaging links directly to the installation flow in the app.
🔌 Installation Steps (Overview)
1. Turn the old TRV head anticlockwise and remove it from the valve body — no tools needed in most cases. 2. Identify the valve type in the tado° app and select the correct adapter (if any). 3. Fit the adapter (if needed) and screw/clip the tado° head onto the valve body. 4. Insert batteries, scan the QR code in the app, and follow the pairing and calibration steps. 5. Assign the thermostat to a room in the app and set its schedule. First installation typically takes 15–20 minutes; subsequent units take around 5 minutes each.

Frequently Asked Questions
Do I need to buy anything else alongside this pack?
Only if you don't already have a tado° Starter Kit. These Smart Radiator Thermostats are add-on devices — they connect via the Internet Bridge included in your existing tado° V3+ (or V3 / V2) Starter Kit. If you haven't installed a Starter Kit yet, you need to purchase and set up one first. You only ever need one Internet Bridge per home, regardless of how many Smart Radiator Thermostats you add.
Will these work with my tado° Wired / Wireless Smart Thermostat Starter Kit?
Yes — the Smart Radiator Thermostats are compatible with all tado° V3+ Starter Kit types: the Wired Smart Thermostat Starter Kit, the Wireless Smart Thermostat Starter Kit (with or without hot water control), and the Smart Radiator Thermostat Starter Kit. They connect via the Internet Bridge in your Starter Kit.
Can I install these myself without a plumber?
Yes — no plumbing skills or tools are required. The TRV head simply unscrews from the valve body and the tado° head screws or clips on in its place. No water is drained and no pipework is opened. The tado° app guides you through the entire process, including adapter selection and calibration, with step-by-step instructions specific to your valve model.
My radiator valves are different makes — will the adapters cover them all?
Very likely yes — the six adapters included with each unit cover the vast majority of UK and European valve bodies. Use the tado° Compatibility Checker on tado.com to confirm your specific valve models before purchasing. If you have an unusual or older valve body, the checker will indicate whether an adapter is available or whether additional adapters need to be sourced.
How do these interact with my existing room thermostat?
The Smart Radiator Thermostats work alongside your existing tado° room thermostat or receiver (from your Starter Kit). When any Smart Radiator Thermostat signals it needs heat, the boiler is called via the Starter Kit's thermostat or receiver. The room thermostat and Smart Radiator Thermostats coordinate automatically through the tado° system — you don't need to manually manage the interaction.
Do all of these features require a subscription?
No — the tado° app, Smart Schedule, remote control, Air Comfort, Energy IQ, Weather Adaptation, and manual Geofencing / Open Window notifications are all free. The optional Auto-Assist subscription (£2.99/month or £24.99/year) automates Geofencing and Open Window Detection so the system acts without requiring you to respond to push notifications. Auto-Assist also unlocks Care & Protect advanced heating system monitoring. It can be cancelled at any time.
How many Smart Radiator Thermostats should I install?
For best efficiency, tado° recommends fitting them on all radiators in heated rooms. Mixing tado° Smart Radiator Thermostats with old manual TRVs can create situations where the uncontrolled manual TRVs either restrict flow or overheat rooms, working against the tado° system. A full rollout — one per radiator — gives you complete system-level control and maximises energy savings. The Quattro Pack is ideal for covering four rooms in one purchase; additional packs can be added at any time.
Can these be used in communal buildings where I don't control the boiler?
Yes — the Smart Radiator Thermostats can operate as standalone devices even if you don't have control over the building's boiler. They control the radiator valve directly, regulating how much hot water flows into your radiator based on your setpoint. They can make your individual radiators smart independently of the building's central boiler control — a particularly useful feature for flats and apartments with shared heating systems.
Are these compatible with tado° X devices?
No — the V3+ Smart Radiator Thermostats are not compatible with tado° X devices or the Bridge X. The V3+ and tado° X platforms use different wireless protocols and are completely separate product ecosystems. If you have a tado° X system, you need Smart Radiator Thermostat X units instead. If you have V3+ (which this pack is for), continue expanding with V3+ add-ons.

The bathroom only needs heat in the morning. The home office heats up quickly and cools slowly due to computer heat. The tado° Smart Radiator Thermostats solve this by giving each radiator — and therefore each room — its own independent temperature schedule and setpoint, managed intelligently alongside the central boiler control.
Universal Valve Compatibility — 6 Adapters Included Per Unit
Each Smart Radiator Thermostat in this pack comes with six valve adapters, covering virtually all standard UK and European thermostatic radiator valve bodies. The thermostat body itself connects via the universal M30 × 1.5mm thread — the most common TRV connection thread in the UK. The adapters allow it to fit on top of valve bodies from all major manufacturers where the thread differs from M30 × 1.5mm.
The tado° app's compatibility checker covers thousands of specific radiator valve makes and models, identifying which adapter to use and guiding you step-by-step through the fitting process — including the correct pin configuration for your valve. No specialist tools are required; the unit simply unscrews from the old TRV head and the tado° head screws or clips on in its place. No water is drained, no pipework is disturbed, and there is no risk of water leaks during installation.

🔍 Check Before You Buy
Use the tado° Compatibility Checker at tado.com to confirm that the Smart Radiator Thermostat V3+ is compatible with your specific radiator valve model before purchasing. Enter your valve brand and model (often printed on the valve body or available from the installer's paperwork) and the checker will confirm compatibility and identify the correct adapter. Compatibility covers the vast majority of standard UK TRV valve bodies.
How tado° Multi-Room Control Works
When Smart Radiator Thermostats are added to a tado° Starter Kit setup, the system becomes genuinely intelligent at the whole-home level. Here's how the heating logic works:
- Each Smart Radiator Thermostat continuously measures the temperature in its room and compares it to the scheduled setpoint for that room at that time of day.
- If a room is below its setpoint, the Smart Radiator Thermostat opens its valve and signals the tado° system that heat is needed. The tado° Starter Kit (your room thermostat or receiver) then calls the boiler to fire.
- When a room reaches its setpoint, its valve closes. When all rooms have reached their setpoints, the boiler call is released and the boiler stops — no energy is wasted maintaining a temperature that's already been achieved.
- Rooms that are scheduled to be at their minimum away temperature (e.g. 15°C) simply don't call for heat until the next heating period begins, even if the rest of the house is being heated.
✅ Boiler Efficiency Note
For the best efficiency with Smart Radiator Thermostats, tado° recommends fitting them in all heated rooms — not just some. When some radiators are controlled by old manual TRVs and others by tado° Smart units, the old manual TRVs may restrict flow to warmer rooms while tado°-controlled rooms correctly call for heat, creating a mismatch. Full coverage allows tado° to properly orchestrate the whole heating system. With this Quattro Pack covering four rooms, consider how many more radiators in your home would benefit from smart control and whether additional packs are needed.
Installation — Typically 5–20 Minutes Per Radiator
The tado° Smart Radiator Thermostat is designed for DIY installation with no plumbing knowledge required. Crucially, no water draining is needed — the TRV head is separated from the valve body by a separate pin mechanism, meaning the valve body itself (which contains water) is never disturbed. You simply remove the old TRV head and fit the tado° head in its place.
The tado° app guides the installation process step by step for each unit, including a calibration sequence that the thermostat runs automatically when first powered on — it opens and closes the valve to measure its full travel range and set its zero position. The QR code on each unit's packaging links directly to the installation flow in the app.
🔌 Installation Steps (Overview)
1. Turn the old TRV head anticlockwise and remove it from the valve body — no tools needed in most cases. 2. Identify the valve type in the tado° app and select the correct adapter (if any). 3. Fit the adapter (if needed) and screw/clip the tado° head onto the valve body. 4. Insert batteries, scan the QR code in the app, and follow the pairing and calibration steps. 5. Assign the thermostat to a room in the app and set its schedule. First installation typically takes 15–20 minutes; subsequent units take around 5 minutes each.

Frequently Asked Questions
Do I need to buy anything else alongside this pack?
Only if you don't already have a tado° Starter Kit. These Smart Radiator Thermostats are add-on devices — they connect via the Internet Bridge included in your existing tado° V3+ (or V3 / V2) Starter Kit. If you haven't installed a Starter Kit yet, you need to purchase and set up one first. You only ever need one Internet Bridge per home, regardless of how many Smart Radiator Thermostats you add.
Will these work with my tado° Wired / Wireless Smart Thermostat Starter Kit?
Yes — the Smart Radiator Thermostats are compatible with all tado° V3+ Starter Kit types: the Wired Smart Thermostat Starter Kit, the Wireless Smart Thermostat Starter Kit (with or without hot water control), and the Smart Radiator Thermostat Starter Kit. They connect via the Internet Bridge in your Starter Kit.
Can I install these myself without a plumber?
Yes — no plumbing skills or tools are required. The TRV head simply unscrews from the valve body and the tado° head screws or clips on in its place. No water is drained and no pipework is opened. The tado° app guides you through the entire process, including adapter selection and calibration, with step-by-step instructions specific to your valve model.
My radiator valves are different makes — will the adapters cover them all?
Very likely yes — the six adapters included with each unit cover the vast majority of UK and European valve bodies. Use the tado° Compatibility Checker on tado.com to confirm your specific valve models before purchasing. If you have an unusual or older valve body, the checker will indicate whether an adapter is available or whether additional adapters need to be sourced.
How do these interact with my existing room thermostat?
The Smart Radiator Thermostats work alongside your existing tado° room thermostat or receiver (from your Starter Kit). When any Smart Radiator Thermostat signals it needs heat, the boiler is called via the Starter Kit's thermostat or receiver. The room thermostat and Smart Radiator Thermostats coordinate automatically through the tado° system — you don't need to manually manage the interaction.
Do all of these features require a subscription?
No — the tado° app, Smart Schedule, remote control, Air Comfort, Energy IQ, Weather Adaptation, and manual Geofencing / Open Window notifications are all free. The optional Auto-Assist subscription (£2.99/month or £24.99/year) automates Geofencing and Open Window Detection so the system acts without requiring you to respond to push notifications. Auto-Assist also unlocks Care & Protect advanced heating system monitoring. It can be cancelled at any time.
How many Smart Radiator Thermostats should I install?
For best efficiency, tado° recommends fitting them on all radiators in heated rooms. Mixing tado° Smart Radiator Thermostats with old manual TRVs can create situations where the uncontrolled manual TRVs either restrict flow or overheat rooms, working against the tado° system. A full rollout — one per radiator — gives you complete system-level control and maximises energy savings. The Quattro Pack is ideal for covering four rooms in one purchase; additional packs can be added at any time.
Can these be used in communal buildings where I don't control the boiler?
Yes — the Smart Radiator Thermostats can operate as standalone devices even if you don't have control over the building's boiler. They control the radiator valve directly, regulating how much hot water flows into your radiator based on your setpoint. They can make your individual radiators smart independently of the building's central boiler control — a particularly useful feature for flats and apartments with shared heating systems.
Are these compatible with tado° X devices?
No — the V3+ Smart Radiator Thermostats are not compatible with tado° X devices or the Bridge X. The V3+ and tado° X platforms use different wireless protocols and are completely separate product ecosystems. If you have a tado° X system, you need Smart Radiator Thermostat X units instead. If you have V3+ (which this pack is for), continue expanding with V3+ add-ons.
