13 years, 7 months (approx) after installing this Sanyo mini-split, I've decided the Crankcase heater is wasting too much power on cool spring days & mild summer nights.
Not sure when it comes on, but it might be around 50F.
It's 86F now, and in the morning it will drop to 44F.
Now that power cost is 30 cents per KWh, I'm noticing all the power being used this spring when no heat or cooling was needed. The heater connection could be unplugged during mild weather. (upper left of diagram) Or, I could add on a toggle switch to made it easier to switch on or off as needed.
Anyone have any pros or cons?
