remote evaporator is located in
each compartment and can provide separate
temperature controlled areas.
Microprocessor Controller
TG-V
Thermo King has applied the newest
technological advances to develop a
programmable microprocessor controller that
controls unit functioning and displays operating
information quickly and accurately.
Features include:
Thermometer:
Displays return air temperature
with 0.1 degree accuracy.
Thermostat:
Provides temperature control from
-20 to 80 F (-28 to 28 C), in 0.5 degree
increments.
Defrost Control:
If the evaporator coil temperature
is below 42 F (6 C), Defrost is automatically
initiated every 4 hours during pulldown until the
return air temperature is in-range. At in-range
temperatures (between approximately 7 degrees
above and 7 degrees below setpoint), the
controller is programmable for 2 to 16 hours in 2
hour increments. The Defrost interval is set at the
factory, but can be reprogrammed by your
Thermo King dealer.
Fuel Saver:
Can be programmed to delay high
speed operation for optimum fuel economy.
Alarm:
Can detect and display alarm conditions
including sensor, microprocessor and defrost
termination failures.
The TG-V Controller is programmed to lock out
High Speed Heat if set below 15 F (-9.4 C).
Cab Control Box:
The Cab Control Box allows the
driver to control and monitor some of the unit
functions from inside the cab. The auto start
system controls the preheat, run, and start relays
to automatically start the unit when all On/Off
switches are in the On position.
Refer to the Operating Instructions for detailed
description of the controller functions.
