Problems With Controllers
The temperatures differ on the remote control and sauna thermometerSome difference in the measured temperature is considered normal because of the measurement uncertainties of the devices. If the difference is more than 10-15 degrees you should check your temperature sensor and sauna thermometer.
You probably need to replace your temperature sensor when even after fixing all the above-mentioned issues:
There could be a problem with the cable connection. Take down the sensor and try connecting it to the main module using another suitable cable. If the sensor works, you just need to replace the cable. If it still does not work, the sensor needs to be replaced. In these cases, please contact us at support@usbathstore.com |
The remote control display does not turn onIn most cases, this happens when the cables of the remote control are not connected correctly.
