PARAMETER DEFINITION RANGE
COMP NORMAL BANDWIDTH The compressor load and unload normal 0 - 20 PSID
bandwidth define when the compressor
will increase or decrease capacity. If the
difference between the setpoint and system
control parameter is greater than the
bandwidth the compressor will load or
unload continuously.
COMP CONTROL DEADBAND The compressor load and unload normal 0 - 20 PSID
deadband define a zone around the
setpoint where no loading or unloading
will be performed.
STANDBY MONITOR TIMER The standby monitor timer is used to limit 0.1 - 99.9 MIN
compressor starts after lead list changes
or when previously failed compressors are
brought back on-line.
HSTG SUCT PRESS MIN SETPT This optional parameter may be used in 29.9 INHG – 185.3 PSIG
(OPTION) the Booster stage of two-stage
refrigeration systems. The High Stage
Suction Pressure Minimum Setpoint is
used to ensure that the Suction Pressure
of the High Stage compressors is below a
minimum value before a Booster
compressor is allowed to start.
