Select Your Kit
If your Wiser Radiator Thermostat isn’t behaving as expected - perhaps it’s not connecting to your HubR, isn’t pairing correctly, or you’re moving the device to a new heating system - a factory reset is often the quickest way to get everything working again.
A factory reset clears the thermostat’s existing system binding so it can be rejoined. The process is simple, but it’s important to follow each step carefully to ensure a clean reset.
This guide with video walks you through exactly how to factory reset your Wiser Radiator Thermostat, based on Schneider Electric’s official instructions.
Why You Might Need to Factory Reset Your Wiser Radiator Thermostat
There are several valid scenarios where a factory reset is useful:
- You’ve replaced your Wiser HubR or upgraded to a 2nd Gen Hub
- The thermostat needs to be moved to a new room or system
- You’re re‑commissioning after troubleshooting connection issues
- You’re setting up the device in a different property
Wiser’s smart radiator thermostats can be reset manually at any time, making the process flexible and user-friendly.
Before You Start: Learn What a Factory Reset Does
A factory reset will:
- Remove the thermostat’s binding to the previous Wiser heating system
- Allow it to be detected and added as a new device
- Trigger a full recalibration after reset
- Remove any schedules you’ve set for the device
It won’t erase the Wiser Home app, schedules, or data for any other devices - only the thermostat you reset.
How to Factory Reset a Wiser Radiator Thermostat
Watch our Wiser Radiator Thermostat Factory Reset Video Guide or follow the steps below.
Step 1: Twist and Hold the Cap in the "-" Direction
Start by twisting the thermostat cap towards the “–” direction and hold it there firmly.
This initiates the reset sequence.
Step 2: Wait for the Centre LED to Flash Red
After a few seconds, the centre LED will begin flashing red.
This indicates the thermostat has entered reset mode.
Step 3: Continue Holding for 8 Red LED Flashes
Keep the cap twisted and held in the “–” direction.
Wait until the LED flashes red eight times — this may take around 20 seconds.
This long‑press ensures you don’t accidentally trigger a reset.
Step 4: Release the Cap
Once you’ve counted eight red flashes, release the cap.
All three LEDs will flash once to confirm that the thermostat is resetting.
Step 5: Allow the Device to Complete the Reset
After the confirmation flash, the thermostat will reboot and prepare to rejoin a system.
Reset confirmation behaviour is identical in the user guide, which also states:
- The device can be reset manually at any time
- The same steps apply even while the thermostat is mounted
When the reset is complete, your thermostat is ready to be paired again using the Wiser app.
What to Do After Resetting Your Thermostat
Once the device has successfully reset:
1. Re‑add it in the Wiser App
Go to:
Home → Settings → Add Device
The app will detect the thermostat as a new unit ready to join your system.
2. Allow the Thermostat to Calibrate
After reset and reconnection, the thermostat may run a short calibration process to position the valve correctly.
3. Reapply Your Schedules (if needed)
Schedules remain stored at the system level, but if you’re joining a new system, you may want to configure fresh settings.
Troubleshooting Reset Attempts
If the reset doesn’t seem to initiate:
- Double‑check that you are twisting firmly toward the minus (-) direction
- Make sure you continue holding long enough - it can take ~20 seconds before all flashes are complete
- Look for the correct LED behaviour:
- Initial red flash after a few seconds
- 8 red flashes confirming reset sequence
-
All 3 LEDs flashing once confirming factory reset
Whether you’re moving devices between homes, replacing your HubR, or resolving communication issues, this step-by-step guide is the reliable way to restore the thermostat to a clean, ready‑to‑pair state.
