I have a Blue Series (Zigbee) - Smart Fan Switch that I want to replace my rotary speed selector switch with.
There are two (2) fans connected this rotary switch.
Lights are on a separate rotary switch, which I am also replacing with a Red Series (Zwave) - Smart Dimmer switch.
Are there any issues that there are two (2) fan units that will be controlled by these switches??
In the manual for the VZW35-SN Blue Fan Switch:
do not use the VZW35-SN load output to control no more than indicated, which is: 2.5 Amps (Resistive Load), No more than two (2) fans to the same switch, and use only with split-capacitor or shaded-pole ceiling fan motors (unless using for a bathroom exhaust fan to which the max load is 2.5A)
So, provided that as a pair they don’t draw more than 2.5A, then there probably won’t be an issue.
I don’t recall the specific post, but I think I remember reading that someone who had done this wasn’t able to utilize the high fan speed on their fans (or something like that), although I won’t claim my memory is 100% accurate.
Another option would be to use two Blue switches and two Blue canopy modules, where the switches remotely control the canopy modules to avoid any potential issues with multiple fans on the same switch. For this, you could use the Dimmer or the On/Off switch for both, as the switches themselves don’t do any of the actual controlling, and only communicate to the canopy modules over Zigbee binding. If you use the On/Off switch for at least one of them, you can run it is Smart Bulb mode and connect the load through the switch enabling you to use the air gap tab to kill power if needed, as the fan canopy modules would otherwise need constant power and will only attach to one of the existing switch legs.
These (5ft) ceiling fans are older (20+) years old and don’t know the manufacture to reference the max amps.
I will have to open the boxes to see if but runs come down independently, or are the paralleled in the ceiling. maybe I can do each independently.
