You can reset your Kelvin by following the instructions below.
How to reset Kelvin:
Step 1: Unplug the heater from the power socket.
Step 2: Plug the heater back in after about 5 seconds.
Step 3: Press the power on/off button 3-5 times in fairly quick succession or until you hear a double/triple click sound, which indicates the heater has been reset.
Step 4: Press the button, just ONCE more.
Step 5: Your Kelvin heater is now reset!
Once reset is complete, set up and pair your Kelvin again as if doing it for the first time.
Please note that you should only reset the heater when attempting to pair the heater with the Boldr app. Once the heater is paired, there is no need to reset the heater again.
