5.1.

Searching for Indoor Unit

The Infinity System Control will light up and display the Carrier logo and then
begin the commissioning process by displaying "Searching for indoor unit".
A12177
NOTE: If the Infinity System- - compatible indoor equipment (package unit indoor
section, gas furnace or fan coil) cannot be found, the control will display "Indoor
unit not found". This MUST be corrected before the initial power up sequence can
continue, proceeding to the next section, "Searching for outdoor unit." If it is not
corrected, the Infinity System Control will go into its DEMO operating mode. If a
control is operating in Demo mode and you wish to install it with equipment,
navigate to the Installer menu and perform a re- - install to re- - learn the equipment.
TIP: Troubleshoot ABCD communication bus problems by removing all but the
indoor unit and system control from the ABCD bus circuit. As each bus segment is
verified, connect the next component and continue to troubleshoot as required.
