Morning! Sense has recently started identifying portions of my air source heat pump (specifically Mitsubishi P series ducted 42,000 BTU system, one indoor air handler tied to outdoor condenser).
I am wondering the best way to differentiate between the electrical components of the heat pump, such as the compressor, condenser, blower, reversing valve, etc. My principal question is, what clues can I use to decide which part is drawing power? Do some parts draw more in heating vs. cooling? Which parts make up small portions of overall energy usage vs large portions? What differences in the signal can I expect for different parts?
Any information is welcome! The compressor and fan are both variable speed which I imagine will make them more difficult to identify.
One part sense identified draws consistently 440 watts, and appears to only be active in heating mode. It is consistently on at 440 watts while the heat pump is active. I originally suspected it was the blower, however the fan is variable speed, and the 440 watts is constant. In addition, the 440 watts appear to only show up in heating mode.
Any ideas? Any advice or insight would be greatly appreciated! I am eager to track the heat pump’s energy usage as I am running my own personal experiment to prove an ASHP can be cheaper than natural gas in Colorado. Thanks in advance!
