Factory Unit Controller Settings
Use the mobile service app to adjust parameters; menu
paths are shown in each table. Refer to the Unit Controller
manual provided with each unit.
Tables 16 through18 show factory settings (in degrees, %
of fan CFM, etc.). Record adjusted settings on the label
located inside the compressor access panel.
When field installing optional kits and accessories, the
Unit Controller must be configured to identify the option
before it will function. Refer to figures 36 and 37 to
determine whether the Unit Controller configuration I.D.
must change. To configure the option, use MAIN MENU >
SETUP > INSTALL menu path. Press SAVE until
CONFIGURATION ID 1 or 2 appears depending on the
option installed. Change the appropriate character in the
configuration I.D. For example, when an economizer is
installed using a single enthalpy sensor, change
configuration I.D. 1, the second character, to “S”.
