Mini-split use in extreme cold
My question is about using our minisplits in extreme cold weather. The specs for our Fujitsu (AOU15RLS3H) indicate that it functions at its rated capacity to 3 degrees F, and at greater than 73% of rated heating capacity down to minus 15 degrees F. When we get some days and nights of cold weather, below 15 or 20 degrees below zero, is there any advantage to turning off the minisplits? I find that the operating manual and other info don’t give recommendations for methods of operation.
Thanks for any info or suggestions.
