Excellent Fan - Poor Wiring Directions
This is an excellent bathroom fan and can be used as a fan replacement. The directions are lacking in explaining how to wire the fan and lights. With reference to page 12, the switch connected to the BLACK fan wire is called the MASTER switch and the switch connected to RED fan wire the MODE switch. To operate the fan the master switch needs to be ON. If the MODE switch is ON when the MASTER switch is turned ON the fan will run at the rated speed. If the MASTER switch is turned ON and the MODE switch is OFF the fan motor will not run. If both switches are ON the fan motor will run at the rated speed. If after both switches are ON and then the MODE switch is turned OFF, after the time set by the "TIME" control, the fan motor will run at the speed set by the "CFM" control. The fan will run at this reduced speed until the MASTER switch is turned OFF. In order, to operate all four functions(MASTER, MODE, Light, and Night light) independently four single pole switches would be required.
If one would like to use one three coductor wire, three switches, and have the light on when the fan is running the FAN wire (BLACK) and the LIGHT wire(RED) would be connected to the same single pole switch. If the MODE switch is then turned OFF, the light be go "OFF" and the fan will complete it cycle of operation.
Operation with two single pole switches and one three conductor wire.
With two single pole switches this fan and light can be arranged to operate in a wonderful manner. One switch is connected to the MASTER line(Black wire) of the fan and to the wire of the night light(Red wire). The second switch is connected to the mode wire of the fan(Red wire) and the light wire(Blue wire).

Can we put a timer on the exhaust fan? Can we have separate switches for the heater and the light?
An external timer can be used on the master power line but it would be redundant to do so because the model ZN110L included a timer which is preset for about 30 minutes of operation after the mode switch is turned OFF. This setting can be changed - see page 12 of Installation Guide.
Three switches are recommend for the model - one for the MASTER power, a second for the MODE and a third for the LIGHT. It is possible to operate the unit with two switches if the MODE and LIGHT are powered by the same switch. This model does not have a heater so no heater switch is necessary for this unit.

DO YOUR VENTILATION FANS HAVE A FLAP OR DOOR IN THE OUTLET TO KEEP THE COLD OR HOT AIR FROM COMING BACK IN.
Thank you for your question on the model ZN110L multi-speed exhaust fan/light/night light. The ZN110L does have a back draft damper included on the unit housing where the duct work connects. We also recommend having a roof or wall cap (where the duct work exits the house) with a damper included.

Is this fan supposed to run all the time?
Our builder installed this fan and it never goes off. They claim it is supposed to run 24/7 all the time. That makes no sense and it should eventually go off. Please advise ?
Thank you for your question on the model ZN80L multi-speed exhaust fan/light/night light. The ZN80L will run continuously at a user set low speed. The fan was designed for use in the new air-tight houses that need constant ventilation. The installation instructions are available for download from our web site and they explain how the fan works. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.

I am bench testing this fan, and cannot get it to change air speed.
Your wiring diagram does not show the internal switching action for the Master and Mode switches. Using an airflow meter, I am getting about 60 CFM on the bench regardless of the CFM switch setting, and only when power is applied to the black and white leads from the fan. Applying power to the red lead has no effect. I purchased three of these, and all three show the same behavior. Can you please provide internal switching diagram to clarify the switch wiring?
Thank you for your question. The ZN80L will not operate according to specifications unless it is fully installed, and connected to duct work. For further assistance, contact Technical Support at 888-336-6151.
