The display indicates room temperature when the sys-
tem is on and is blank when the system is off.

to decrease as room temperature is approached in the
COOL mode. The fan will operate at low speed when
set point is satisfied. Manual fan speeds can be selected
with the FAN button.

or heating is required. Under normal conditions the au-
tomatic fan speed operation is reversed in the HEAT-
ING mode, however the fan can be programmed to oper-
ate the same as in the COOLING mode.
The Passport control features a memory back-up that does
not use batteries or other power sources. When power is
lost operating parameters are held indefinitely.
When power is resumed, the control continues as last

mediately release the POWER button so as to not unin-
tentionally enter the program mode.

mode, the Passport control will maintain a 2 degree Fahr-
enheit differential.

The cabin temperature will be maintained atwithin 2 de-
grees of set point.

grees Fahrenheit of set point.
When the heating and cooling is satisfied, the compres-
sor cycles off and the fan returns to low speed. The fan
speed will remain constant if MANUAL FAN SPEED
