For anyone with the 4 button Duo-Therm thermostats this is wonderful. This thermostat has been obsoleted by Duo-Therm and replaced with a 5 button thermostat. It gets expensive because the control boards in your a/c's have to be changed--I've got 4 air units! OUCH.
The normal problem with these thermostats is that the buttons quit functioning. This company will repair your unit for $90.00. The four button Duo-Therm 4 button thermostats were used from sometime in the early 90s into the mid 2000 when it was replaced with the new 5 button.
