Installing a timed switch to control the fan
Hi. I have installed a Lutron countdown fan control timer to control the fan and it seems not to run at full power. Have you encountered this? Do you have any suggestions for installing a timer to control the fan?
The Lutron switch I used was model number MA-T51.
Thank you for your question on the model QTXEN050 exhaust fan. You can use any simple line switchable timer on this exhaust fan. Some electrical timers can cause strange operation of the exhaust fans and we would not recommend using them. Since the unit is not tested with the Lutron MA-T51 electronic timer, we cannot tell you how it would operate with it.

I have two QTXEN110S-B fans which appear to not work (they came with the house and are probably 7 years old). The indicator light on humidity/timer control unit blinks about 9 times, then is solid for a few seconds before blinking again. I tried toggling power on-off-on to the fans, but that doesn't appear to change the behavior. It seems that the unit is getting power, but is it possible the humidity/timer unit isn't working correctly?
Thank you for your question on the model QTXEN110S-B humidity sensing exhaust fan. The normal mode is 5-seconds on and off. If it blinks rapidly for 5-seconds and then off, check the sensor connections on the grille and fan housing. If the connections are good, the problem could be in the control assembly or the sensor (which is part of the grille assembly). Please contact the Technical Service Department at 888-336-6151 for further assistance.

can I disconnect the sensor so it only runs off a switch
If I can disconnect the sensor can you sent a link to the wiring diagram.
It seems like the fan comes on to much with the sensor attached.
Thank you for your question. Additional information is required to assist you further. Please contact Nutone Technical Support at 888-336-6151.

Can I keep a 4" duct with the QTXEN150
The QTRN110F-C is great but doesn't move enough air in our large bathroom (we're most concerned about moisture).
The QTRN110 unit has a 4" duct, while the QTXEN uses a 6". The question of the day: can I install the QTXEN and use a 6x4 adapter/reducer to get the air to the existing exhaust vent? I don't want to pull the old one from the roof unless absolutely necessary...
Thank you for your question on the model QTXEN150 exhaust fan. The QTXEN150 must be installed with six inch duct work. It cannot be installed with four inch.

I have just had 3 of these fans installed in new construction and they are all very noisy. What can cause this problem?
Thank you for your question on the model QTXEN110 exhaust fan. When installed properly, the QTXEN110 is a very quiet exhaust fan. First make sure that everything up inside the unit housing is tightened securely. Make sure the back draft damper is opening when the fan is turned on. This unit should be installed with six inch, preferably rigid, duct work. The use of flexible duct work, too small of duct work and too long of run of duct work can cause more noise. Please contact the Technical Service Department at 888-336-6151 for further assistance.
