description
Defines the period between the end of defrost cycle and beginning of the next defrost cycle. A time-
based defrost cycle helps improve evaporator efficiency.
considerations
l
In the event of power loss, the defrost duration (dE) is not maintained. The defrost interval is reset.
l If icing up occurs, review the values of the defrost parameters.
range 0 to 199 hours
global default 06 hours

10.17 differential (dIF)
The table below details the differential (dIF) parameter.
display
description
Defines the compressor cut-in temperature when added to the set point (SPC or S PF) temperature dur-
ing the ready mode.
considerations
If the differential (dIF) is set too low, for example, less than 2.0°Cthe compressor may cycle on the min-
imum compressor rest time (rt).
range 0.0 to 9.9°C (0 to 18°F)
global default
4.0°C (7°F)
ems75sz: 3.0°C (5°F)
