Hi my name is***** you tried to reset the thermostat? When the thermostat gets replaced from the older 4 style button the boards in the ac units also need to be replaced, on the boards are some dip switches, so if the reset does not work I would verify and make sure the correct boards are in the units and that the dip switches are in the proper positions. To do the reset turn the thermostat OFF, hold the top and bottom buttons at the same time, turn the thermostat ON, you should see FF when you see FF release and see if it is working properly.... I am not sure what you have tried... Robert
