Hello reed_nj

This is one way to do it, Power goes to the fan first..If the thermostat
calls for power, your new switch will not shut off the fan..

Hope this helps

Let us know how you made out with your wiring project

Have A Nice Day

Thanks Linesman. Diagram makes sense, although not sure if the wiring at the fan is accessible. I'm getting the fan tomorrow, but I think between the fan and the thermostat the wires are in a flexible conduit. If the wires are only exposed at the thermostat, is there still a way to wire it up parallel?

If you look at the diagram again you will see two wires added to the thermostat that run to the new switch. You should only add the wires at the thermostat.

OK...I see that. And the two wires from the power source go to the fan? If so, not sure where they would connect to due to the conduit.

Is your purpose to be able to turn on the fan without the thermostat? Or is it to energize the fan and let the thermostat do what it was designed to do?

The latter....allow the thermostat to control the fan when temps get high enough, but also I want to be able to turn the fan on at any time.

Received the fan today and it answered my question. Inside the thermostat housing, the wiring setup allows for connections both before AND after the thermostat. This will allow me to connect the extra wire from the new switch to the thermostat wire that's "downcurrent" of the thermostat switch.
