My 30 y/o central air system is being replaced this week with the folowing:
4TEE3C04A1000A Air Handler
4TTX60036 xl16i Condenser
TCONT803A Thermostat
Aquecoil hydrocoil for heat (new zone off oil fired boiler)

Looking at the Owner's Manual for the air handler I don't see "Comfort R" mentioned anywhere. Is that feature supposed to be available on this model? Also, there is a plastic hinged access door on the removable service panel that doesn't seem to have any function. It seems the right size to allow operation of the user interface panel and display but doesn't line up with it. Thanks for any feedback.
