Please let me preface this request for information from a group of flashlight geeks, but I have often been amazed at the depth of knowledge on an amazing variety of subjects, the membership here holds.
I have a attic fan. It has a 36 inch box, and I suppose a 30 inch three bladed fan. It can move a LOT of air. I imagine that it should be able to move enough air to give the attic a complete change of air in about 15 minutes, yet it runs for hours at a time.
I am using this as a thermostat.
It is supposed to start the fan at the temp it is set at, and turn the fan off when the temp is 7-8 degrees less.
A couple of nights ago, it didn't turn the fan off until 3:30 AM.
The fan's drone is loud enough that I heard it go off. It does impair my sleep.
Here's the question:
Is there a programmable thermostat, that will not only monitor the ambient temperature but also the outside temp? one problem may be that the outside temp may be above the OFF temp of the fan. If so, the fan will run all night long. This will not only keep me awake, but it will have additional energy costs.
