Using attic heat to warm up basement

Xringer · 06-20-14, 03:19 PM

It was getting too hot in the back hall and in the low 70s in the basement.

Summer mode:
I've unplugged the attic blower and used the X10 to power the old
attic exhaust fan (it vents to the outdoors).

That old exhaust fan has it's own thermostat (on@120F & off@100).

So it's enabled by the CAI program (via X10), but might not run.
(If it's not hot enough in the attic).
The basement fan will still run whenever it's commanded by the program.

Today isn't very hot, so only the basement blower is running.
