For those of you still following this thread...
I kept track of the system cycling today just to see what happens. The house was open last night and cooled to 70 degrees on its own. I closed everything up this morning and set the thermostat to 75 (cooling only of course). The outside temp reached a high of 94, bright sunshine.
Here's a rough chart of how it's run today so far:
First on cycle: 2:58PM, 91 deg outside, run time 10 min, off time 19 min
3:27PM, 92 deg, run time 11 min, then off 13 min
3:51PM, 93 deg, run time 11 min, then off 10 min
4:12PM, 94 deg, run time 13 min, then off 8 min
4:33PM, 94 deg, run time 12 min, then off 8 min
4:53PM, 94 deg, run time 14 min, then off 7 min
5:14PM, 94 deg, run time 20 min, then off 7 min
5:41PM, 94 deg, run time 20 min, then off 6 min
6:07PM, 93 deg, run time 23 min, then off 6 min
6:36PM, 92 deg, run time 29 min, then off 7 min
7:12PM, 90 deg, run time 24 min
I bought a cheap Radio Shack digital thermometer with humidity display. It shows a range of 50%-51% RH the whole time today, usually 51% at the start of a cycle and 50% at the end of the cycle. The condensation drain line is putting out though.
Any comments on these numbers?
Thanks everyone.
