High Speed Pull-Down Frozen
The controller can initiate a High Speed
Pull-Down to setpoint of frozen loads at or below
15 F (-9.4 C).
Settings:
YES = Enable High Speed Pull-Down to
setpoint.
NO = Normal operation. Do not enable High
Speed Pull-Down to setpoint.
2 Minute Low Speed Start (Continuous
Run only)
This setting allows the engine to warm-up by
running it in low speed for 2 minutes when the
unit is first started. After 2 minutes, the unit will
resume normal operation.
This setting functions only while the unit is
operating in Continuous Run.
Settings:
YES = Enable 2 minute low speed start.
NO = Normal operation. Do not enable 2
minute low speed start.
Reduced Setpoint Range
Smaller truck units are not designed to operate
with a setpoint range of -20 to 80 F (-28 to 28 C).
For these units the setpoint range must be reduced
to 0 to 80 F (-18 to 28 C).
This setting is programmed at the factory. Change
it only when replacing the controller, and then
only to the original factory setting for your unit.
Settings:
YES = Reduce setpoint range to 0 to 80 F (-18
to 28 C).
NO = Do not reduce setpoint range.
