TP-Link Kasa Smart Thermostatic Radiator Valve - Quick Start Guide
01 / Check Compatibility
1. Check existing valve type
There are two types of valves: Thermostatic and Manual. The Kasa Smart Thermostatic Radiator Valve is only compatible with the thermostatic valve.
Thermostatic Valve: [Compatible]
Manual Valve: [Incompatible]
2. Check the connector type
If your connector is M30 x 1.5, you can screw the new valve onto the radiator directly. If not, check whether one of the provided adapters fits the connector. If none of them fit your connector, please purchase a proper one yourself.
Connector Types and Adapters:
- M30 x 1.5 (Direct fit)
- RA Adapter
- RAV Adapter
- RAVL Adapter
(Visual description: Diagrams showing M30 x 1.5 connector, RA Adapter, RAV Adapter, RAVL Adapter, with dimensions like 1.5mm and 30mm.)

02 / Install Requirements
Read the following instructions first before installing the new valve:
- Install the valve first before powering it up.
- No need to shut off water before changing the radiator valve. Water will not leak.
- Avoid installing the valve in the same room where you have installed the boiler thermostat.
- Install the valve within range of your Kasa smart hub if you wish to control it using the Kasa Smart app.
03 / Install the Valve
- Unscrew the existing valve. (Visual description: Illustration of unscrewing the existing valve.)
- Screw the new valve directly (for M30 x 1.5 connector) or after installing the proper adapter (for non-M30 x 1.5 connectors). The indicator at the bottom of the valve shows the display position. (Visual description: Illustration of screwing the new valve directly or with an adapter.)
- Remove the cover of the valve by rotating counterclockwise using the provided [Cover-Opener Tool]. (Visual description: Illustration of removing the valve cover using a tool.)
- Open the battery cover and insert two AA LR6 Alkaline batteries. Make sure the positive and negative terminals face the correct direction. (Visual description: Illustration of inserting AA batteries into the valve, showing correct terminal orientation.)
Installation Orientation:
- Horizontal Installation (Visual description: Diagram showing horizontal installation.)
- Vertical Installation (Visual description: Diagram showing vertical installation.)
Note: Do NOT use rechargeable batteries or 1.2V AA batteries.
04 / Set Up the Valve After Install
If you want to remotely control / manage the valve, you need to add a Kasa smart hub first.
- Set up a Kasa smart hub in the Kasa Smart app if you haven't already done so. You can get the Kasa Smart app from [Download on the App Store] or [Get it on Google Play].
- Use the provided [Cover-Opener Tool] to press and hold the SYNC/RESET button for 5 seconds to reset the valve.
- Open the Kasa Smart app, tap [+] and select Smart Thermostats. Follow the app instructions to pair the valve and complete setup.
Don't Have a Hub?
You can adjust temperature manually. After inserting the batteries, the valve is ready to use. Rotate the valve to increase / decrease temperature.

Frequently Asked Questions (FAQ)
Q1. What should I do if the display shows [Error: Calibration Needed]?
Rotate the valve, and then the valve will calibrate automatically. Check if the valve is installed properly. Check if the connector is M30 x 1.5. If not, choose a proper adapter.
Q2. What should I do if the display shows [Error: Valve Blocked]?
The valve might be blocked by calcification. Use a spanner or a similar tool to move the pin in and out to unblock the valve. Re-install the old valve head and open/close it multiple times to improve the pin's movement. Then, restart and remount the new valve. Replace the batteries.
Q3. Why CAN'T I control my radiator valve?
If the display shows [Error: Calibration Needed] or [Error: Valve Blocked], please refer to Q1/Q2. If the display shows [Error: Low Battery], then the battery power is running low and the valve can't work properly. Please replace the batteries. Refer to Q5 to reset the valve and set it up again.
Q4. Can the radiator valve continue to work if there is no wireless connection or no internet access?
You can still manage the valve in the Kasa Smart app as long as your phone is connected to the same Wi-Fi network as the valve. Manual control still works. You can rotate the control knob to adjust temperature. The schedules you have set will still activate as long as the connected hub works properly.
Q5. How can I reset the radiator valve?
Remove the cover of the valve, then use the [Cover-Opener Tool] to press and hold the SYNC/RESET button for at least 5 seconds to reset the valve. Alternatively, open the Kasa Smart app, then remove the valve on the Home page or in Device Settings. The valve will reset automatically.
