Why does the temperature on my Uponor thermostat drop after moving it?
If the temperature displayed on your Uponor thermostat drops after it's moved, it may be influenced by an external heat source. Try changing the location of the thermostat to avoid this.
What to do if room is heated by another heat source with Uponor UponorControl System Temperature Controller?
If a room is being heated by another heat source, it may affect the accuracy of the Uponor Temperature Controller. Try changing the thermostat position to a location less influenced by the other heat source.
Why is nothing displayed on my Uponor Digital thermostat or Timer screen?
If nothing is displayed on your Uponor Digital Thermostat or Uponor Timer screen, it could be because the back plate has been deformed or bent during installation, preventing power from reaching the thermostat. Try loosening the screws on the wall plate to ensure the thermostat’s back part is not deformed, then reinstall the front part and check for power-up after a few seconds.
Why is an asterisk blinking on my Uponor device screen?
If an asterisk is blinking on the screen of your Uponor device, it indicates a short circuit in the sensor connection or a missing sensor. Try replacing the thermostat cable to resolve this issue.
