Does anyone know of a mini-split heat pump that allows you to set the indoor temperature as low as 45-50 F? I'm talking about winter heating here, not a walk-in cooler. I'd like to get one that will allow a very low setting, just high enough to prevent freezing problems while the dwelling is not occupied. I have a Friedrich that only allows settings down to 60 F.
Also, is there a mini-split system that does better than others in cold weather. Can any of them work below 0 degrees F? Do they automatically shut down when it gets too cold. My Friedrich kept right on running (and heating pretty well) down to 10 F. That's as cold as its gotten since installing it.
