I’ve been monitoring my heat pump system for some time not but I’m not so sure it is being calculated correctly. My water heater circuits look to be calculating correctly. The heating elements are about 4.5 KW and that’s what is being calculated for them.
The issue is with my heat pump outside circuit. It’s showing 1.44 KW with 12.5 Amps, 240Volts and .944 power factor. A manual calculation gives me 240 x 12.5 x .944 = 2.832 KW. It’s like it is not doubling the power like it should. I definitely have the “Double” check box selected as you can see below. My configuration for my heat pump input is exactly the same as for a water heater input. Using the same AcuCT-H040-50 CTs for both circuits and they are both 240 VAC.
I can only think that I’ve configured something incorrectly for this input but cannot imagine what it could be. Does anyone have any suggestions?
