How do I start the valve calibration / initialization procedure?

The procedure depends on the valve model. Follow the section that matches your device.

EasyPelt v1.2 (batteryless)

1. Press and hold the button for 10 seconds: the red LED turns on and then off. Release.

2. Wait a few seconds, then press for 3 to 4 seconds (release before the red LED turns on). The valve should move and fully open (you can then refit it onto the radiator if it was removed).

3. Press once briefly to pair and initialize.

4. Wait a few seconds, then press once briefly again.

5. In the interface, check under Settings → Devices that a small green “V” appears next to the valve. If not, repeat step 4.

EasyPelt 1.0 (batteryless, 2 buttons)

1. After fitting the valve onto the valve body, press both buttons for 10 seconds (the indicators flash).

2. Wait a few seconds, then press one of the two buttons for 5 seconds (the green LED flashes twice) and check in the interface that the valve has communicated.

3. Press once briefly on a button to start initialization (stroke measurement). For about 10 minutes, the valve communicates more frequently (every 10 seconds).

EasyPelt Cube (batteryless)

1. After fitting, press the button for 10 seconds (the red LED flashes once).

2. Wait a few seconds, then press twice quickly (the red LED flashes once) and check in the interface that the valve has communicated.

3. Press once briefly to initialize (stroke measurement). For about 10 minutes, the valve communicates more frequently (every 10 seconds).

Classic Snugr valve (battery-powered, no display)

1. Press once on the button with the antenna symbol to drain residual energy.

2. Reinsert the battery and wait for the red LED to flash.

3. Screw the valve back on by hand.

4. Press briefly on the button with the spanner/tool symbol: the red LED should turn on and then off after a few seconds. If it never turns on, replace the batteries and try again.

Snugr valve (battery-powered, with display)

1) Initialization (stroke calibration)

1. Press and hold the white button for more than 10 seconds until this symbol appears: =>X.

2. Wait for the display to turn off.

3. Press the white button once briefly.

   • You should see a symbol with a large arrow and a dot: this means the valve is initializing based on the stroke of the pin in the valve body.

4. Wait for the display to turn off again.

5. Press the white button once.

   • The valve should now display a temperature (and two small arrows at the top of the screen).

At this stage, the valve is working but in manual mode. It is no longer paired with Snugr and lets you control the radiator temperature like a standard thermostatic radiator valve.

2) Pair the valve back to Snugr

1. Press and hold the button until this symbol appears: =>

2. Then press the button once briefly.

3. Check the display:

   • If it shows only a temperature (and nothing else), the valve is correctly paired with Snugr.

   • If other symbols remain or no temperature is shown, repeat the last two steps.
