Updating in case anyone has some more insight,
The heat pump has been working as it should throughout the day, but once it hits target temp, it shuts down and wont start back up even when the water temp drops. I initially thought it was reaching a temp limit of 95 and shutting down. Now it will reach 99 before shutting down and not starting up, regardless of time of day. The temps haven't gotten too cold here, at least not while the heat pump is running. We didn't use it last night, so its kept a lot of heat in. It's currently at 90. At some point I remember the PB telling me there has to be 5 degree difference between the max and set temps, max is 104, temp of 99 would be the 5 degree difference. I have it set to 101 to see if it will hit it or not.
