compressor rest time (rt)
The table below details the compressor rest time (
rt
) parameter.
display
description
Defines the minimum time between compressor cycles.
The compressor rest time ensures that the pressures in the refrigeration system have time to equalize
during compressor off-cycles.
The compressor rest time (
rt
) helps to avoid the following:
l
passing peak current through the windings of the compressor motor
l
switching off the system on the thermal overload protection
l
short cycling of the system.
considerations
If set too low, the compressor rest time may cycle on the set point
(
S P
) and differential (
dI F
) temperatures or the saving set point
(
S S P
) and saving differential (
S d
) temperatures.

saving differential (Sd)
The table below details the saving differential (
S d
) parameter.
display
description
Defines the compressor cut-in temperature, when added to the saving set point (
S S P
) temperature, dur-
ing the
saving mode
.
considerations
If the saving differential (
S d
) is set too low, for example less than 2.0°C, the compressor may cycle on the
minimum compressor rest time (
rt
).
