Mine is not installed in shower, but seems to be coming on too often, possibly responding to A/C floor vent.
Thank you for your question on the QTXE110SFLT. If your fan is responding to often to environmental changes or conditions, adjustment toward 80% RH may be required. To adjust the humidity you will want to turn off power to the fan. Through the grille you can locate the humidity screwdriver slot. Using a small, flat blade screwdriver, carefully rotate 'humidity' adjustment toward 50 or 80. Next, turn the power on and check the operation by turning on the shower or other humidity source until the fan turns on. Repeat these steps if necessary. If you need further assistance, please contact our Technical Support Department directly at 800-637-1453. They will be happy to try to help you more.
