Buy Remote Thermostat For AC (controlled by Android app) ?

neschultz is right on. The RV thermostats are not the same as residential and are not directly interchangeable. I have rewired my AC/furnace control boxes in all my RVs to use a better t-stat with less temp difference between on & off. Thus I could use a residential t-stat. I've not searched on-line for a product that will work; maybe someday someone will make one.
