I have two systems:
System 1) carrier 38YDB048 with variable speed FE4ANB005 and infinity control.
System 2) carrier 38YDB048 with variable speed FE4ANB006 and infinity control.
When I go into advance menu in the control and look at the equipment summary in System 2 I see a line for Heater: 9V but I don't see that in System 1.
1) Is that 9V thing the the auxiliary heat KFCIEH2901N09 in System 2?
2) Does that line not showing in System 1 means that aux heat is not present or could it mean the system in not configured correctly meaning 9V is not configured for this system but it might actually be there in the air handler?
Thanks for the help,
