62-11175 COMFORTPRO SERVICE MANUAL

1.1.2 How the ComfortPro Operates
The ComfortPro has two modes of operation: manual and automatic.
Manual Mode
You start the APU from within the truck bunk using the On/Off button on
the driver control panel (DCP). Once the APU is running, you can start and
stop the fan, heater and air conditioning using the DCP. See page 1-3.
Once the heater or A/C is running, it will cycle (automatically turn on and
off) in order to keep the truck bunk at the temperature you specify. The
HVAC will continue to cycle until you turn it off. While the HVAC is cycling,
the APU remains on and will only turn off when you manually turn it off
using the button on the DCP.
Note that in manual mode, the APU remains on until you turn it off. But in
Comfort Monitor mode (described below), the APU automatically turns off
and on as required.
When the APU is running, power is supplied to the power outlet in the
truck bunk (except in high heat).
In manual mode, the APU will turn off automatically if the Maximum Run
Time is reached.
Automatic Mode
The ComfortPro has several functions that will start it in automatic mode.
Comfort Monitor
(page 1-7)
FEATURE
DESCRIPTION
The APU and HVAC automatically turn on to
maintain a comfortable temperature in the truck
bunk. When the desired temperature is met, the
APU and HVAC automatically turn off. When the
temperature is again out of range, they will both
turn on again, and cycle heat and air conditioning
as needed.
Timer
(page 1-8)
At the specified time, the APU and HVAC
automatically turn on. During the specified
timer duration, the HVAC cycles on and off to
maintain the desired temperature. When the
timer duration expires, both the APU and HVAC
turn off automatically and remain off.
Cold Weather Watch
(page 1-10)
The APU and heater on the HVAC automatically
turn on in order to prevent the APU engine and
truck engine from getting too cold. (Turning on
the heater creates a “load” that makes the APU
work harder and therefore warm up faster).
Both the APU and HVAC turn off automatically
once the preset duration time expires.
The APU automatically turns on for 90 minutes
in order to recharge the batteries. The HVAC
does not turn on. After the 90 minute run time,
the system will sense voltage for 10 minutes,
before restarting if needed.
Battery Monitor
(page 1-12)
There are icons on the DCP that flash when the APU and HVAC are running.
See page 1-1. If you enter the truck bunk and APU or HVAC is on but you
did not start it, you can assume it has started in one of the automatic
modes, as described above. On the DCP, one icon will be flashing steadily:
this is the icon for the mode that is currently operating.
Whenever the ComfortPro is running in automatic mode, if you then press
the heat, A/C or fan buttons on the DCP, the ComfortPro will switch to
manual mode. The APU will not automatically turn off! This icon on the
DCP will also stop flashing.
