Figure 4−2 Continuous Operation Switch Points With Eco Mode Set To - Carrier VECTOR 6500 Operation & Service Manual

When Null Mode is required and the system is operating
in:
• Engine Operation, the compressor will shutdown
+3.2_F (+1.8_C )
+1.6_F (+0.9_C )
+0.9_F (+0.5_C )
Set point
-0.4_F (-0.2_C)
-0.5_F (-0.3_C)
-3.6_F (-2.0_C )
+ results are above set point, - results are below set point
Switch points are the same for Perishable Range and Frozen Range except
in Frozen Range heating is not allowed.
* If the HIGH SPEED PULLDOWN Configuration is set to YES, transition
from pulldown is delayed from the indicated +3.2_F (+1.8_C ) transition
temperature until the temperature is +0.36 _F (+0.2_C) above set point.
