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 (or one (1) for cool only mode
if a/c unit has 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.
U 3 LOW FAN SPEED LIMIT: The low fan speed limit determines the lowest output allowed for the low fan speed. The
range of values is 30 through 55 in arbitrary units. The factory default is 50.
Both the high and low fan limits may be adjusted as follows: While the system is off, start the fan by pressing and holding
the FAN button until the number "1" appears in the display. Enter the program mode while the fan is running and select "U2" or
"U3". Raising and lowering the fan limits while the fan is running allows the programmer to experience fan speed changes as they
are made. Once the high and low fan speed limits are set, the system will automatically reprogram itself to produce six equally
spaced fan speeds between them.
U 4 COMPRESSOR STAGING TIME DELAY: The compressor staging time delay is provided for use where more than
one a/c system is being operated from the same power source. Setting the staging delays at different intervals allows for only one
compressor to start at a time to lessen the amperage load on the power source. The minimum delay is five (5) seconds and the
maximum is one hundred thirty five (135) seconds. The factory default setting is fifteen (15) seconds (or one hundred thirty five
(135) seconds if a/c unit is cool only).
U 5 TEMPERATURE CALIBRATION: Use this feature to calibrate the air sensor within a range of "108 F. The factory
default is 08 .
U 6 COMPRESSOR FAIL-SAFE PROTECTION: This feature is provided to monitor the refrigerant circuit. When a high
head pressure condition occurs the display will flash "HHH", when the refrigerant system is low on pressure "PPP" will flash only
if the optional low pressure switch is installed. This display indicates that the system requires maintenance. See the
TROUBLESHOOTING GUIDELINES in this manual. The four parameter settings are:
Zero (0): Turns off all protection, no action is taken and no message displayed.
One (1): No message displayed with 90 seconds between continuous restarts.
Two (2): Message displayed with 90 seconds between continuous restarts.
Three (3): Message displayed with three 90 second restarts, manual reset is required.
The factory default is three (3).
U 7 FAHRENHEIT OR CELSIUS TEMPERATURE DISPLAY: The PASSPORT II can display temperature in either
degrees Fahrenheit (8 F) or degrees Celsius (8 C). Setting to zero (0) displays 8 F and setting to one (1) displays 8 C. The
factory default is zero (0).
U 8 ALTERNATE AIR SENSOR OPERATION: Installing an alternate remote air sensor will override the face plate (digital
