Monitor and Control Off-cycle Defrost
With High Offset (Cut-in) being governed by evaporator temperatures, the refrigeration system will remain off until at
least one evaporator temperatures exceeds set-point by one degree. With a set-point of 40°F, the high-offset would
be 41°F; With a set-point of 65°F, the high-offset would be 66°F. This method allows the evaporators to fully defrost
before cooling is initiated (See Figure 2-17).
