Standard Vehicle Configuration

p3 dm 08.03.001

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 includes vehicles equipped with Detroit Diesel Optimized Idle (O/I). Both configurations are operated in the same way, the differences are in how the batteries and charging system are configured. Refer to "Standard Vehicle Configuration" or "Vehicles with Detroit Diesel Optimized Idle" below for more information on your vehicle.

The ParkSmart™ climate control panel replaces the standard sleeper control panel in ParkSmart-equipped sleeper cabs. The ParkSmart HVAC system is designed to maintain a comfortable temperature 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 temperature 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.. 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 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 batteries. The available power for other vehicle-supplied accessories (house loads) will be affected when running in this mode. If there is no Low Voltage Disconnect (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 batteries 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 temperature 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 curtain closed. See Table. for recommended settings for comfort while the vehicle is parked. See Table. shows the temperature knob setting for desired temperatures.

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 Table. or Table., depending 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 batteries, the ParkSmart run-time will be less than expected.
