trip condition lasting longer than 7 minutes. When four
consecutive or ten total CODE 2 events are recorded,
the module will lockout the compressor and flash red
two times.
C C O O D D E E 3 3 – Pressure Switch Cycling: The module will
flash yellow three times when the compressor operates
from 12 seconds to 15 minutes followed by a trip
condition lasting between 35 seconds to 7 minutes.
When four consecutive or ten total CODE 3 events are
recorded, the module will lockout the compressor and
flash red three times.
C C O O D D E E 4 4 – Locked Rotor Trip: The module will flash
yellow four times when the compressor trips within 12
seconds of operation and does not reset and start
within 35 seconds. When ten consecutive CODE 4
events are recorded the module will lockout the
compressor and flash red four times.
C C O O D D E E 5 5 – Compressor (Moderate Run) Trip: The
module will flash yellow five times when the
compressor has operated between 15 minutes and 18
hours, followed by a compressor trip lasting longer
than 7 minutes. When four consecutive or ten total
CODE 5 events are recorded, the module will lockout
the compressor and flash red five times.
C C O O D D E E 6 6 – Open Start Circuit: The module will lockout
the compressor and flash red six times if the module

Alert Condition
Normal Run Solid
Normal operation, no alarm status.
Green
Long run time. Compressor is running for more than 18 hours at full load.

(CODE 1 is disabled in heat pump mode.)
Yellow Flash 1
Compressor pressure trip. Compressor runs for 12 seconds to 15 minutes
CODE 2
followed by a compressor trip condition lasting longer than 7 minutes.
Yellow Flash 2
Pressure switch cycling. Compressor runs for 12 seconds to 15 minutes
CODE 3
followed by a compressor trip lasting 35 seconds to 7 minutes.

Compressor moderate run trip. Compressor runs for 15 minutes to 18 hours
CODE 5
followed by a compressor trip lasting longer than 7 minutes.

detects a demand signal in the Y terminal and current
in the S winding of the compressor, but no current is
detected in the S winding of the compressor for 2
seconds.
C C O O D D E E 7 7 – Open Run Circuit: The module will lockout
the compressor and flash red seven times if the module
detects a demand signal in the Y terminal and current
in the S winding of the compressor, but no current is
detected in the R winding of the compressor for 2
seconds.
C C O O D D E E 8 8 – Welded Contactor: The module will flash
yellow eight times if it has detected line currents in the
S and R windings and demand is absent for 15
seconds.
C C O O D D E E 9 9 – Low Voltage: The module will flash nine
times if the module supply voltage drops below 17 Vac
for 2 seconds. The module will prevent the compressor
from starting until adequate voltage is established.
C C O O D D E E 1 1 0 0 – Over-Current Protection: When the current
at the PROT terminal is greater than 2A for 40
milliseconds, the module will flash a CODE10. The red
LED will flash 10 times with the yellow LED remaining
off. This event will cause a lockout of the compressor
and indicates that the module is mis-wired or the
contactor coil is shorted to ground.
