ZWAVE 3 DRY CONTACT RELAY

[shennecke]

Looking for a 3 dry contact Zwave relay to control a 120 volt three speed fan.
All I have found is a Zooz Zen16. This would work but dislike that it is powered by low voltage, usb c. Would like it to be powered by 120 volts. Anybody have any ideas?

Greetings shennecke,

What's the plan to prevent two or more relays from being energized at once thus damaging the fan? There are ways to do this but it requires more space and requires more than one piece. Take a look at the Zooz ZEN52.

What's the current draw of the fan?

They make three and four speed in-wall fan controls for Z-Wave.

Yes would need to be able to do interlock logic to prevent more than one speed to be energized at a time.

What's the current draw of the fan?
8.61 amp on high

Yes, I currently use one of those on a ceiling fan. This is a whole house fan that requires 3 dry contact closure wiring for the three speeds.

Thanks for your help.

A zwave one like you are looking for doesnt exist as far as I know. There are better and less expensive options than zwave for this. With the mcsmqtt plugin and a dingitan relay board is one example. Check out that subforum for more details, it's well documented.

Bond bridge and plugin should also work if you have a remote with the fan.
