Comp Status:
This will display the status of each
compressor. Possible status values include:
If multiple alarms are present, only the highest
priority alarm will appear. Alarms are listed top-to-
bottom by priority (with ‘Suct
Trans Fail’ being the
highest priority, and ‘OK’ being the lowest).
o
Suct Trans Fail
: Activated when the
suction transducer reading is out of
range.
o
Dis Trans Fail
: Activated when the
discharge transducer is out of range.
o
Comp High Dis Trip
: Activated when a
Comp Proof Fail and High Dis Pressure
alarm activate together.
o
No Comp Proof
: Activated when the
compressor signal is on, but suction
pressure and discharge pressure are
within 20PSI of each other.
o
High Suct. Press
: Activated when the
suction pressure increases above the
upper pressure limit (varies per mode)
during dehumidification or cooling call.
o
Low Suct Press
: Activated when the
suction pressure decreases below the
lower pressure limit (80PSI).
o
High Dis Press Alarm
: Activated when the
suction pressure increases above the
upper pressure limit (500PSI).
o
OK
: Compressor is running properly.
o
Comp Low Suction Trip
: Activated when
a compressor’s suction pressure drops
below the safety limit (75PSI by default).
Compressor will instantly shut down and
lock out until suction rises to an
acceptable level.
o
Gradual Shutdown
: Activated when the
discharge
pressure
of
a
digital
compressor is above the warning limit.
Digital compressor will gradually reduce
capacity in 20% increments until
discharge
pressure
drops
to
an
acceptable level.
o
OA Temp Comp Lockout
: Activated when
the outdoor air temperature is too cold to
allow compressors to run.
o
Economizer Lockout*
: Activated when
the economizer is active.
*If Equipped.
