It was rainy, windy and overcast all day. But there was a short burst of dim sunshine. Didn't last long.

The orange plot (DHW) can be seen going up, all the time the A7 was running.
The blue trace (basement) does the invert of the water temp..
The A7 really chills that part of that basement..
Once the A7 shuts off, you can see the warm air starts heating up the basment
fairly fast..

At "A little sun", the water temp climbed because of PV heating..
The sun was so weak, I never expected to see a 'bump'..

Edit:
As far as I can tell, the RH sensor is reading 10 to 12% higher than the 'real' RH.
I'm not 100% sure, but when I compare my RH with the local Underground Weather and the accuweather.com site,
my RH sensor reads 10 to12% too high during very damp weather.

So, in order to get a RH setpoint of 70%, I have to use 80% as my setpoint.
