  • What are the expected types of switches to use when running in continuous mode? Just plain single pole, push button, or timer countdowns?

    I'd like to have the full cfm mode run for a user definable time based on a wall timer/switch (typically 0-60 minutes in 5 minute increments), not the user adjustable time in the fan unit, then fall back to continuous mode.
    Asked by: Kevin
    Thank you for your question regarding the switches. The recommended switches are simple, single pole design. Outside additional timers are not recommended with this model. There is an adjustable, internal, on-board timer which should be used. It may be set between 5 and 60 minutes. The installation instructions are available on our website for download.

    6 inch ridgid vent, what is that, sewer pipe? Maybe?

    Asked by: Jimbo
    Thank you for your question. Rigid duct work is metal pipe. Typically made of rolled sheet metal or galvanized steel. The ZN80 requires the use of 6&rdquo; round pipe for proper air flow.

    I installed an ZN80 and wired the black to a switch and red wire to the hot for continued operation. The fan did not operate using the cmf and time.

    Did I wire this correctly?
    Asked by: Chuck
    Thank you for your question on model ZN80 multi-speed exhaust fan. It is recommended that you use two switches so all power can be cut off if there is a need for repair or cleaning inside the unit. If you are only hooking one switch to this fan and hard wiring the low speed, you would need to hard wire to the black wire and switch the red wire.

    Fan speed for AV closet

    I am using this fan in an AV closet. It is wired to an attic thermostat that kicks on at 90F. It doesn't seem to be running at the highest cfm of 80 when it does kick on. What settings should I use on the fan to ensure continuous 80 cfm while running? I want the fan to run until temperature drops below 90F.
    Asked by: FIZBAN
    Thank you for your question on the model ZN80 exhaust fan. The ZN80 is designed to run continuously at a low speed and come up to high speed when a second switch is turned on. If you have the thermostat connected as the second switch, it should work. The way this fan is designed, it has to have duct work connected to it for the fan to work properly. If the fan is simply exhausting the air into the attic, without duct work connected, it will not work properly. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.

    Is there a continuous vent fan with one light switch? I see in the instructions 2 switches One switch would be easier, as right now I have one switch

    Is there a continuous vent fan with one light switch? I see in the instructions 2 switches One switch would be easier, as right now I have one switch and an old, vent unit.
    Asked by: Jimbo
    Thank you for your question. The XB80 is a single speed unit that can operate on a single switch. For further assistance, contact Technical Support at 888-336-6151.
