What is the Lowest Temperature Setting on the MrCool Mini Stat? - Ask the Expert Episode 229

Today's question is from Mark Steven Lorenzen. "Hey Dan, how low can you set the MrCool Mini Stat thermostat? Will it go to 56 degrees?" What is the lowest temperature setting on the MrCool Mini Stat?

Ok, so for those of you who don't know about the MrCool Mini Stat, it's essentially a wall thermometer for the MrCool Ductless Mini Split. They are made by MrCool for their heat pumps, their ductless units.

It's got temperature settings from 50 to 99 degrees cooling and 40 to 90 degrees for heating. So, yes, you could do 56 degrees. Obviously, you have to make sure the ductless unit you have will actually cool down that low. The mini stat is just a thermometer, it can't magically make a mini split that won't go down to 56 go down to 56 degrees.

So if you have a heat pump ductless unit that only goes down to 60, well it doesn't matter how far the mini stat will go down. You need to make sure they could sync up like that.

Any more questions? Just ask in the comments below.

    Hi Dan!
    I want to use the MrCool in a cool room. Can I make the ac go down to 40F?

    The lowest temperature to which a MrCool mini-split can cool a room would be around 60 degrees.

    I have a home that is in Luray, Va. and I am thinking of putting in Mr.Cool Heat pump for, especially heating to keep it from freezing pipes in winter. It has high ceilings and is 1200 square feet. Will this work to do this, especially since I am not going to be there all the time (maybe once a week for now) and if there is electrical outage can what can I set up as back up or is there another solution to this?

    Properly sized, a heat pump could effectively heat and cool that space. To make sure a unit keeps running after an electrical outage, get a unit with an auto-restart function.
