started the unit does not shut down on
thermostat demand. The unit runs
continuously until it is turned off manually.
The start sequence, once initiated, is the
same for both systems. Refer to the
CYCLE-SENTRY sections of this manual for
further information on the start sequence, as
it applies to the Auto Start system.

Units on Diesel Operation
Selection of Operating Modes on
CYCLE-SENTRY Equipped Units
The Thermo King CYCLE-SENTRY system is
designed to save refrigeration costs. The savings
vary with the commodity, ambient temperatures
and truck insulation. However, not all temperature
controlled products can be properly transported
without continuous air circulation.
Since highly sensitive products will normally
require continuous air circulation,
CYCLE-SENTRY units come equipped with a
selector switch for CYCLE-SENTRY or
Continuous Run operation. Your selection of the
operation mode for the proper protection of a
particular commodity should use the following
guidelines.
Ambient Temperature Preheat Time
32 to 60 F (0 to 16 C) 30 seconds
0 to 32 F (-18 to 0 C) 60 seconds
Below 0 F (-18 C) 90 seconds
CAUTION: Never use starting fluid.
