I have two Mitsubishi MSY-GE18NA units, both 220, both cooling only. I was able to install a CT on each and now have them both monitored. Since they are cooking only, I turned on their fans before killing the breaker. That was how I was able to identify which CT was which and got lucky that they were labeled correctly from the start. I am seeing a standby of 12w always for the past week. I’d turn them off over the winter, but I want to make sure there no heater in them that comes on over the winter. I’ll leave these breakers live all winter, and if there’s never any extra element that kicks on, next fall I’ll turn these breakers off and save a couple dollars. So far Sense is estimating they’ll cost $6 each for the year.
