Thanks Jack. :cool:
Day 1 - Fan cycled once, about 15 minutes into the hour it took to get the house from 65 to 70.
Day 2 - NO CYCLING!!! Ran about an hour to get from 65 to 70.
The fan speed conundrum has also been solved, it would seem that the heat exchanger isn't robust enough for the fan to run at full speed. Fan speed does not change with the AC, only the heat, and the difference is only known when you switch fan operation from "auto" to "on"
