coolant. While the engine is running, the ParkSmart
batteries are also being recharged by the vehicle
electrical system.
When the engine is off with the key in the ACC or
ON positions, A/C mode is powered by the
ParkSmart batteries. The cab fan will also circulate
air in the cab using power from the main vehicle bat-
teries. The available power for other vehicle-supplied
accessories (house loads) will be affected when run-
ning in this mode. If there is no Low Voltage Discon-
nect (LVD) control on the main electrical system, the
ability to start the vehicle could also be compromised
if this mode is activated for an extended time period.
When the engine is off with the ignition switch in the
OFF position, the ParkSmart system runs the
battery-operated A/C or diesel-operated coolant
heater, depending on the temperature requested,
and power is drawn from the batteries. The main bat-
teries and the ParkSmart batteries will both be used
until the system voltage drops to 12.5 volts, then the
system will switch to the ParkSmart batteries only.
The ParkSmart system will run until the dedicated
batteries reach 11.3 volts.
Before operating the ParkSmart system, bring the
sleeper interior temperature to the desired tempera-
ture with the engine running and the bunk curtain
open. The ParkSmart system is designed to maintain
an established comfortable bunk temperature, in
parked mode, for up to 12 hours with the bunk cur-

shows the temperature knob setting for desired tem-
peratures.
To use the ParkSmart control panel, select a fan
speed (other than off) and push the PARK button.
Adjust the temperature control knob to the desired
temperature. Refer to
pending what mode is being used.
Start the fuel-operated heater once per month and
allow it to run for 15 minutes. Periodically running the
heater will keep fresh fuel in the lines and ensure the
heater is ready to perform when needed.
IMPORTANT: Wait three minutes after shutting
down the ParkSmart system before turning the
cab load disconnect switch (CLDS) to OFF.
NOTE: The Espar Hydronic 5 water heater can
use biodiesel blends up to 10% (B-10). Consult
the engine manufacturer's manual to confirm the
lowest allowable blend (engine or heater) is not
being exceeded.
IMPORTANT: The condition and charge of the
auxiliary batteries will directly affect run time of
the ParkSmart system. If the vehicle run-time
between discharges is less than eight hours, or
if additional loads are added to the auxiliary bat-
teries, the ParkSmart run-time will be less than
expected.
