I've been working on an new way to control when the A7 (ASHP) runs.
It was on a timer that enabled 120AC to the A7 in the early afternoon.
In the hopes there was a lot of sunshine during the morning hours.
Now, I'm working on using a micro controller (CAI) to monitor
the water temperature, solar conditions etc, to optimize performance.

During the last 5 or 6 days, that I've been working on the CAI programing,
all my time has been spent on other stuff and the A7 has been unplugged..

Meaning, we've been using nothing but solar PV heated hot water!
It's not boiling hot, but it's doing the job, this week..
