ICC Controls
L7 – Compressor Open
Run Circuit
The ICC detects current
in the Start circuit but
not the Run circuit of
the compressor four (4)
times in one compres-
sor call • Check for damaged,
miswired, or wrong run
capacitor
• Check for broken wires,
loose connectors, or
miswired compressor
• Check compressor
windings for continuity
09 – Low Secondary
Voltage
The secondary voltage
at R and C is below
18VAC
• Control transformer
overloaded
• Low line voltage

Information
21 – Low Pressure Con-
trol Open
The ICC detects the LPC
is open.
Note: The low pressure
control is ignored for
the fi rst 120 seconds of
compressor operation
• Unit has low refrigerant
charge
• Air coil is frozen
• Dirty air fi lter or air coil
• Blower is not running
• Expansion valve is not
operating properly
Flashing
L21 – Active Protection
Low Pressure Control
Trip
LPC has opened 3
times in the same com-
pressor operation, the
ICC has locked out the
compressor to protect
it. ICC alternately
fl ashes L and 21
27 – Low Line Voltage
or No Line Voltage
Fault
• Check incoming line
voltage to the discon-
nect and unit
• Check wiring connec-
tions
28 – High Line Voltage
Fault
• Check line voltage
29 – High Pressure
Control Open
The ICC detects the
HPC is open
• Dirty air fi lter or air coil
• Blower is not running
• Liquid line restriction
• Excessive Refrigerant
charge
Flashing
L29 – Active Protection
High Pressure Control
Trip
HPC has opened 3
times in the same com-
pressor operation, the
ICC has locked out the
compressor to protect
it. ICC alternately

30 – Fuse Open
The ICC detects the
on-board fuse is open
• The 3-amp fuse on
the ICC is open
• Low voltage wiring at
R and C is damaged or
miswired
80 - Low Air Flow
The ICC detects that
the blower is not
providing the minimum
airfl ow requirements
• Wrong blower motor
confi guration
85 – Low Water Coil
Temperature
The ICC detects the
water coil temperature
below the selected
setpoint
• Low water fl ow
• Water pump not run-
ning

86 – Low Air Coil Tem-
perature
The ICC detects the air
coil temperature below
the setpoint
• Low airfl ow

93 – Internal Control
Fault
The control is not func-
tioning properly • Check control for
proper system opera-
tion
• Replace control
d1 – No Shared Data
The control board does
not have shared data • Replace memory card
with correct system
information
d3 – Airfl ow CFM
Mismatch
The blower cannot sup-
ply the required airfl ow
for proper system
operation
• Misapplied/wrong
blower – replace with
properly sized blower
d4 – Memory Card
Invalid for Device
The memory card is
missing or the data in
the memory card does
not match the data in
the control
• Check memory card
to ensure it matches
device
• Check if memory card
is present
d8 – Old Shared Data
System data is obso-
lete
• If system will not oper-
ate, order new memory
card to update system
