Happy with device. This is my second review, with greater satisfaction
After having the product in use for 10 months now, we are happy with the device. It works as described. I found the only difficulty I have with it is that the micro plug under the grill is difficult to grasp for removal or installation of the grill.

How many watts? Important for solar house application!
Thank you for your question on the model ZN80M motion sensing multi-speed exhaust fan. The ZN80M will draw a maximum of 0.3 Amps (approximately 36 watts).

Which brand/model number multi-function switch do you recommend for this fan?
We will be using all three wall switch options: Master, Sensor and Manual on individual switches with 14/4 wire.
Thank you for your question on the model ZN110H humidity sensing multi-speed exhaust fan. To have independent operation of all functions of the ZN110H, you would need three switches and the associated wiring. We have a multi-function switch (model 66) that will fit into a single gang box that will work fine with this unit. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.

What motion detector wall switch brand/model would you recommend?
Thank you for your question on the model ZN110M motion sensing, multi-speed exhaust fan. The ZN110M has a built-in motion sensor and we would not recommend using an additional motion sensor switch on the wall. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.

What is the maximum recommended length for the duct?
Thank you for your question on the model ZN110H humidity sensing, multi speed exhaust fan. This fan is designed to use six inch rigid duct work. You can run this duct work 90 feet straight without loss of CFM. For every elbow installed, you would need to reduce that length by six feet.

Why does the fan run at the user set speed for about 30 seconds, then I hear a switch kick in and it runs at full speed continuously?
It is wired correctly on a retro install black - blk/brn, white - white, and grounded. Humidity level in the room is RH 36% per a meter I have, and the user setting is set at 80% for the sensor and time set at 20 min. User speed is set at 50cfm, 5 min. The sensor pin/plug is seated correctly, along with the other two pin/plugs for power.
Thank you for your question on the model ZN110H multispeed exhaust fan with humidity sensor. Wiring the ZN110H with a single switch, the fan will come on to low speed and then move to the high (rated speed) for the user time set and move back to low speed after the time has elapsed, until the humidity sensor turns the fan to high speed again. If this is not the way it is working please contact the Technical Service Department at 888-336-6151 for assistance.
