compressor rest time (rt)

The table below details the compressor rest time (rt) parameter.
display
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.
description The compressor rest time (rt) helps to avoid the following:
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.

If set too low, the compressor rest time may cycle on the set point

(S S P) and saving differential (S d) temperatures.
