For my whole house fan, I only want it to run when it is ABOVE a certain temp - say 65 degrees. Below this temp (say in the middle of the night), I want the fan to cut off until the temp returns to 65 degrees or higher. If this switch doesn't do the job for me, can you recommed a switch that does? My windows are open during all periods that I would consider running the fan.
Thanks!

Answer: 
It may be possible to use this thermostat with your whole house fan. There are several issues that should be considered before doing so. I would recommend calling our HVAC tech team to discuss these issues. 800-472-4643

Answer: 
No, this thermostat is backwards for what you want - you want a switch that closes on temperature rise - or one that has SPDT switch contacts so you can switch on either way.

The Grainger 2E834 is one such thermostat, or search for 'thermostat' and 'spdt' to find other possibilities. Also, any 'attic fan controller' should fill the bill.
