Idle, the fan will not operate with the key in acces-
sory mode. Optimized Idle may also turn the fan off
to reduce stress on the batteries. Refer to
Chap-
ter 11
for more information.
NOTE: When the cab air conditioner (A/C) is on,
the sleeper fan will operate at low speed even if
the sleeper fan switch is in the off position. This
is necessary to protect the evaporator in the
sleeper heater and air conditioner system from
freezing. In lower fan speed settings, a slight
increase in airflow levels may appear at times,
as the control acts to regulate the evaporator
temperature.
Temperature Control Switch
The temperature control switch is used to select the
desired temperature in the sleeper. Turn the switch
counterclockwise for cool air, or clockwise for hot air.
Air Conditioning Button
The A/C cools and dehumidifies the air inside the
sleeper. Press the air conditioning button, located in
the center of the temperature control switch, to turn
the A/C on and off.
ParkSmart
™
HVAC System
There are two variations of the ParkSmart vehicle
configuration. The standard configuration is the most
common, and includes all vehicles without Detroit
Diesel Optimized Idle (O/I). The second variation in-
cludes vehicles equipped with Detroit Diesel Opti-
mized Idle (O/I). Both configurations are operated in
the same way, the differences are in how the batter-
ies and charging system are configured. Refer to
"Standard Vehicle Configuration" or "Vehicles with
Detroit Diesel Optimized Idle" below for more infor-
mation on your vehicle.
Standard Vehicle Configuration
The ParkSmart
™
climate control panel replaces the
standard sleeper control panel in ParkSmart-
equipped sleeper cabs. The ParkSmart HVAC sys-
tem is designed to maintain a comfortable tempera-
ture inside the sleeper, and can operate in
combination with the cab climate control system
when the vehicle is running, or independently when
the vehicle is parked. It uses a set of four dedicated
batteries mounted aft of the starting batteries, either
between the frame rails behind the cab or outside
the frame rail.
The ParkSmart climate controls operate similarly to
the standard sleeper climate controls. The tempera-
ture settings range from 60°F (15°C) to 85°F (29°C),
with 74°F (23°C) at the very center of the range. The
fan switch activates the fan. The fan switch has eight
fan speeds. Zero (0) is the OFF position. See
Fig. 8.6
. To operate the fan switch, turn the switch
clockwise to increase airflow; turn the fan switch
counterclockwise to decrease airflow.
The ParkSmart HVAC system operates both when
the engine is running and when the engine is off.
When the engine is running, the air conditioning
(A/C) is powered by the vehicle electrical system,
while the auxiliary heater core is supplied with engine
