      Comments about Honeywell Prestige IAQ Deluxe Comfort System - YTHX9421R5077:

      This replaced a previous top of the line Honeywell. The main reason for its use is that the existing mounting location is on an external wall and as a result the thermostat does not read the room temperature accurately (as the cold from the external wall interferes).

      The idea of having a remote hand held unit - which can also be designated to function as the thermostat to measure the room temperature - is invaluable in my application.

      Honeywell have also done a magnificent job in rewriting the user interface. It is extremely easy for a non technical person to program this thermostat.

      Five stars and well worth it.
