  If your Uponor Thermostat is making the room too cold, it could be due to several reasons. The thermostat setting might be too low, so try increasing the temperature setpoint. The thermostat's location could be influenced by an external heat source; consider moving it. Individual room thermostats may be incorrectly registered; ensure the thermostat is in the correct room or change the thermostat registration in the controller. There may be an incorrect minimum/maximum limitation; change the minimum/maximum limitation in the interface. In addition, an actuator may not open; in that case, replace the actuator. Contact the installer.

  Fluctuating floor temperatures with your Uponor Thermostat can stem from several causes. The supply water temperature might be too high, so check the boiler or pump. If the heating fall back function is activated due to lost communication with the thermostat, check the connection and batteries of the room thermostat. The thermostat's placement might be in direct sunlight or near other heat sources; verify its location according to installation instructions and relocate if necessary. Also, ensure the thermostat is placed in the correct room; if not, change rooms as needed.

  If your Uponor Thermostat system fails to start, it could be due to a few reasons. First, check that the controller is connected to AC power and inspect the wiring in the 24 VAC compartment, ensuring there is 115 VAC power to the transformer. Also, a blown controller fuse or faulty wiring could be the culprit, so replace the fuse and/or correct any wiring issues.

  If your Uponor Thermostat is causing the room to be too warm (or too cold in cooling mode), it may be because an actuator is not closing. Check that the actuator is correctly installed. If not, replace the actuator. Contact the installer.

How to improve radio reception for my Uponor Thermostat?
- J
  Judith HuffmanAug 27, 2025
  Poor radio reception with your Uponor Thermostat could be due to the antenna being installed inside a metal cabinet or too close to other shielding objects, or the building structure might be unfavorable for radio transmission. Try changing the antenna location. If the problem persists, contact the installer.
