Final Procedures
1.
Check the blue dip switch with the
white rockers. The table above shows
the switch functionality.
2.
If the STATUS LED is blinking, count
the number of blinks in an interval.
The number of blinks will indicate the
fault.
Figure 10
shows the operation
flow and consequences of each fault.
Use the flow chart to back track the
connection error. To the right of the
POWER and STATUS LEDs, a list of
number
of
blinks
and
their
corresponding faults are shown.
1= High Pressure Switch
2= Low Pressure Switch
3= Freeze Protection
4= Condensate Sensor
5= Brownout Protection
A COND error will result in a hard lockout
requiring a restart. All other errors must be
tripped four times to reach a hard lockout, as
set on the dip switch #4 ON, setting #4 OFF
will require only two error trips for a hard
lockout.

IMPORTANT: Freeze Protection Faults
If the unit is not equipped with Freeze
Protection, use the supplied jumper to
short the FREEZE terminals. Open
connections will result in faults and
lockouts.
