Can I Use My Zooz Light Switch With a Fan?

Most Zooz light switches are not rated for use with fans, home appliances, and motor loads in general - but there are a few exceptions.

To have on/off control of your fan, you could use the ZEN71 Switch or the ZEN32 Scene Controller as long as the fan is rated under 3A or installed in the last 5 years. If you currently have a remote control receiver controlling the fan, you'll need to remove it. The reason for this is that the ZEN71/ZEN32 are just basic switches instead of an isolated relay, which means it is passing 120V from the power supply to the output and the specific load; anything on the load side (spikes, inrush current, etc) will directly affect the ZEN71/ZEN32.


If your fan is rated over 3A or is an older installation which typically draws more than it's rated for, we recommend using the relay part of the ZEN30 Double Switch. While the ZEN30 dimmer and relay parts cannot control the speed of your fan (if it has that feature), you'll still be able to control the speed from the pull chain or existing remote control. You can learn more about the types of installations the ZEN30 switch can be used in from this guide.


The relay on the ZEN30 is a dry contact, which means the input is separate from the output, so it is not affected by the load in the way a standard switch is. However, when using the ZEN30 with a fan that contains an existing remote, please note that the behavior may not be as expected. The relay on the ZEN30 will turn on and off the 120V going to the fan; however, if there is something in between the relay and the load (ex. remote control receiver installed in the canopy) that means BOTH the ZEN30 relay and the remote receiver must be in the ON position in order to turn the fan into a working position. If either one of those is turned off (ZEN30 or the remote receiver), this means the power is off to the fan. The remote receiver can be used in conjunction with ZEN30, with the above limitations.


Another method is rewiring the circuit in parallel mode.  In parallel, we have the opposite situation: both ZEN30 and receiver must be OFF to turn the fan off, while either one of those may activate the fan.


If you're looking to keep a toggle-style switch for your fan, then you could install either the ZEN51 Dry Contact Relay for your fan motor, or the ZEN52 Double Relay for your light and fan motor. These devices can be installed behind the switch, or at the light fixture.


The ZEN71/ZEN32 and ZEN30 switches are the only ones rated to handle the specified fan loads. Our other Zooz switches, especially our dimmers, cannot be used with any type of fan. The high inrush current, or amount of power a motor draws at start-up, will damage the switches immediately or over time. Aside from the 2 models rated for use with fans, Zooz switches should really only be used with lighting within the recommended loads. 


If you have the older ZEN21 and ZEN23 switch models (which have been discontinued in favor of the 700 series switches), then you could also use these models as long as the fan is rated under 3A or installed in the last 5 years.

The maximum loads for each individual Zooz switch can be found under Specifications on their product pages.
