..oh, and the fans. Check out the jpg at the top of the webpage... the circulation fans run 2 minutes every 25 minutes; the exhaust fans run 1 minute every 40 minutes. The fountain runs whenever the mister or the climate control is running. Also on today's graph, you can tell that the case ran low on water in the middle of the night because the heating (of the water) wasn't warming the case (as indicated by the same temp 2 hours in a row).
