This sounds like an issue with the Coleman thermostat/controller. I would recommend changing to the Advent which we have either a Manual Air Distribution Box # ACDB or Thermostat Air Distribution Box # ACRG15.

@Edwin With having a new thermostat, controller and AC unit the only other issues is either something wasn't wired correctly or one of the thermostat wires run through the wall is damaged.
