    Honeywell t87f 2873
    The indoor temperature of my old honeywell t87f 2873 is not working so the AC is constantly running. I am looking to replace it with a digital one but I do not know what type of cooling/heating system I have. How can I find it out? Do they sell some sort of universal thermostat that works with any type of system?
    I have a single heat/air conditioning unit Suburban Model DL1220BT

    Any help would be greatly appreciated. Maria Celeste
