Thanks for the link, it should be helpful.
Golan, yes the chiller and fans are more than sufficient. I'd prefer the fans weren't running all of the time and with the controller they could be layered, coming on at different temps. The chiller comes on but there is a 2 degree change in temp during the day. Probably not a big deal, but my heaters aren't very reliable so I'd like to ensure the low temp. Ultimately I'd like to keep the temp to withing 1 degree.
Now if I could only win the lottery to help pay for this stuff!!
