Comp1: These parameters
define the temperature or
pressure at which the
compressor will turn on and
off, and the time delay
associated with those
actions.
Comp 2: These parameters
define the temperature or
pressure at which the
second compressor will turn
on or off, and the time delay
associated with those
actions.
Alarm in Vacuum: When
checked, this parameter will
log an alarm if the compressor
suction pressure indicates that
the system is in a
. vacuum
Compressor 2 as Unloader:
When checked, the second
compressor will be
designated as an unloader.
Control By: This parameter defines
whether the compressors will be
controlled by a temperature or a
pressure sensor reading.
Pump Down: This
defines the type of pump
down and the pump
down target pressure.
Comp. 1 Override and Comp. 2
Override:
These parameters allow
the compressor outputs to be
overridden either On or Off and the
override duration may be set.
