Hello all, helping someone with a QuietCool whole house fan that takes two separate hot wires in to control two speeds.
Can’t have both hots active at the same time, so the wiring diagram shows it’s usually sitting behind a 110v 15a single pole DOUBLE THROW switch to control speed.
The Vision ZL7431US seems to fit the bill (theres a great community article talking about a similar application using this for a pool pump) BUT I cant find a source for the device nor can I confirm if its even still made.
So, suggestions for a US ZWave 110v Single Pole DOUBLE THROW switch or relay?
Alternatively a multirelay that can be configured to simulate a double throw in hardware.
