I had a new Rheem heat pump installed about 2 months ago. Before that, I replaced my single-speed pump with a variable-speed, which I mostly left with the default settings (couple hours high speed, 10 hours low speed, couple more or so at mid-speed).
After installing the heat pump, I adjusted the mid-day speed to the heat pump would run, to 1750 rpm up from 1400. About a month later, I noticed I was getting the low-pressure note on the heat pump, so I adjusted the speed again, all the way to 2100. Now, about a month later, it's giving me the note again, and it won't turn on until I get the speed up past 3000 rpm (max is 3400).
I haven't noticed any other changes, my water level is normal, and I haven't checked water pressure. Any idea what's going on?
