[Shop-talk] attic fan switches (does this exist?)

[Pat Horne]

I’m not familiar with x-10 but I assume you will be using like a controller for a table lamp where the output is a socket. If you have a controller with isolated contacts it’s even easier. 

If you want the x-10 to override  the thermostat so that the fan runs until you turn it off, all you need to do plug a relay into the controller & wire its normally open contacts across the thermostat.

I have an attic fan that is on a thermostatic switch. 

I was wondering if there was a way that I can have it on a  thermostatic switch AND a remote switch (like X-10) 

What happens is that  I want to turn on the fan on some nights or days, but it isn't hot enough to trigger it to go off.  If I reduce the temperature setting, it stays on most on the time. 

But I do want it to go on if it gets too hot when I'm not home. 

Is there anything like this on the market?  I also couldn't figure out how to wire 2 separate switches safely to accomplish this. 

Any ideas? 

Thanks.
