Can a 15k BTU Duo-Therm a/c work with a 4 button thermostat?

I need to replace one of my three air conditioners. I have a 15k BTU Duo-Therm available to me. I want to replace my first a/c unit with it. I don't want to convert to a 5 button thermostat because of the cost of converting my other two a/c circuit boards to a board that is compatible with a 5 button thermostat.

My question is: will a new style Duo Therm work with a 4 button thermostat?

Also has anyone encountered any problems when they converted from a 13k BTU air conditioner to a 15k BTU unit??

    As long as the 15k does NOT have a circuit board built in, there is no problem. New penguin (lo profile) models cannot work with a 4 button. Dometic Heat Pumps cannot work with a 4 button. If you have the square galvanized box that has the control kit, you will have no problem. Doug
