* Specific default settings for cool only a/c units (no heat option installed) should not be changed.
** Default parameter settings may be reprogrammed by user, enter new default settings in this column.
U 1 OPERATING MODE: The operating mode is used to select heating, cooling, or automatic
modes. Zero (0) selects automatic mode, one (1) selects cooling mode and two (2) selects heating
mode. Systems that do not have heating capabilities should be programmed for cooling mode (1). The
factory default is zero (0) for automatic mode for reverse cycle units or one (1) for cool only mode for
units with no heat option installed.
U 2 HIGH FAN SPEED LIMIT: The high fan speed limit can be tailored to suit various motors and
operating conditions. The range of values is 56 through 85 in arbitrary units. The factory default is 85.
