Minisplit Short Cycling and Fan Speed
I am still getting used to my Mitsubishi mini splits. I’ve noticed that if I set the fan on high or super high, it spreads the heat around a lot better. However, the units tend to over-shoot their temperature setting and short cycle if they are on a high fan speed and it warms up outside.
Is there some programming that prevents them from modulating down the compressor if the fan is on a higher setting (to keep the air coming out from being “too cold”)? If so, it seems like these one-to-one units are not really that great at inverting. They can run from maybe 2/3-full compressor rating regardless of what heat is being called for. I tried the auto-fan mode, but it just runs on such a low speed that it doesn’t really heat up the house well and speeds up only after the temp has dropped substantially in the room. I feel like I need to set up an IFTTT script that controls the fan speed on my units to keep them from short cycling. It seems like I must be doing something wrong here.
