How to Install Kasa Smart Thermostatic Radiator Valve

Follow the instructions below to install your Kasa Smart Thermostatic Radiator Valve.

Note: There are two types of valves: The thermostatic and Manual.

Kasa Smart Thermostatic Radiator Valve is only compatible with the thermostatic valve.

Install Requirements

Install the valve first before powering it up.
No need to shut off the 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.

Start Installation

Remove your existing valve.

Install the new valve.

For M30x15mm Connector

Screw your new valve onto the radiator directly. The ▲ the bottom of the valve indicates the position of the display.

For Non-M30x15mm Connector

Fit the suitable adapter onto your radiator connector. Then screw the valve onto the adapter. The ▲ at the bottom of the valve indicates the position of the display.

Power on your valve.

Remove the cover of the valve by rotating counterclockwise using the provided cover-opener.

Open the battery cover and insert two AA LR6 Alkaline batteries. Make sure the positive and negative terminals face the correct direction.

*Do NOT use rechargeable batteries or 1.2V AA batteries.

Set Up the Valve

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 the App Store or Google Play.
Use the provided cover-opener 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.

Note: If you don’t have a hub, you can adjust the temperature manually. After inserting the batteries, the valve is ready to use. Rotate the valve to increase/decrease temperature.
