I'll have to go back and look at some of my postings.. But I think the 70s
might be pretty common during the mild parts of the winter.

It got down into the 30s last night, so it took a while to warm up this morning.


(I love these charts and need to make my own from the CAI data)!

Right now, at 11AM. ----------- At 14:42
61.8 F in the basement----------62.7
58.4 F outdoors -----------------63.4
70.7 F in the attic Peak----------95.1

I had the blower set to come on at 65 F(in attic), and it came on around 10AM.

Not doing much good now, but when I get all the attic hardware installed,
it will be sucking down that warm peak air..

My plan is to program a differential function into the CAI board.
If the RH and time of day are good, it will pump warm air down from
the attic, anytime the attic air is warmer than the basement air..

In the dead of winter, I may have to change to program, so that I can
pump down some no-so-warm air, cool down the basement a little,
pause and let the basement come back up(GeoSlab) to normal and repeat..
Hopefully, I won't have to resort to using the cold air flush..
