Older Sanyo Mini-splits cool&heat units have the Crankcase heater on the compressor, if the unit is 24k BTUh and above.
Not sure about the AC (cool only) models. I don't think they even need it.
Especially since they are turned on when it's already pretty warm outside anyways.
I've noticed mine use about 40W each (I have two units), but they seem to be temperature controlled.
If it's cold night followed by a warm day, I'll check the TED and sometimes, I'll see Zero watts displayed.
But, even without the crankcase heater on, there is still the electronics loads
of the controller boards in the indoor and outdoor units.
My guess is a few watts at the most. Can't see that low on the TED.
