fl ash a "L" on the dual 7-segment LEDs followed by a "86".
IMPORTANT: This mode of active protection must be
manually reset.
5) Compressor Locked Rotor Lockout
The ICC will display a fl ashing "L" followed by a fl ashing "04"
when a compressor locked rotor condition occurs.
Active Protection – Code L4 – Compressor Locked Rotor
If the ICC detects the compressor has run less than 15
seconds for four (4) consecutive starts during the same
command for unit operation, the ICC will lockout the
compressor to keep it from continuing to operate and fl ash a
"L" on the dual 7-segment LEDs followed by a "04".
IMPORTANT: This mode of active protection must be
manually reset.
6) Compressor Protector Trip
If the ICC detects a compressor protector trip it will display
a "P". If the protector doesn't reset within 4 hours, the ICC
display will change to "5".
Compressor Protector – Code P – Protector Trip
7) Open Compressor Start Circuit Lockout
The ICC will display a fl ashing "L" followed by a fl ashing "06"
when a compressor open start circuit condition occurs.
Active Protection – Code L6 – Compressor Open Start
Circuit
If the ICC detects current in the run circuit without
current present in the start circuit, the ICC will lockout the
compressor to keep it from continuing to operate and fl ash a
"L" on the dual 7-segment LEDs followed by a "06".
IMPORTANT: This mode of active protection must be
manually reset.
8) Open Compressor Run Circuit Lockout
The ICC will display a fl ashing "L" followed by a fl ashing "07"
when a compressor open run circuit condition occurs.
Active Protection – Code L7 – Compressor Open Run Circuit
If the ICC detects current in the start circuit without
current present in the run circuit, the ICC will lockout the
compressor to keep it from continuing to operate and fl ash a
"L" on the dual 7-segment LEDs followed by a "07".
IMPORTANT: This mode of active protection must be
manually reset.
Exiting Active Compressor Protection Lockout
There are three methods to reset the ICC after an active
protection lockout:
1) Cycle the line voltage to the unit
2) Cycle 24VAC to the ICC (remove the R or C
connection to the ICC)
3) Push the TEST button down with an insulated probe
for one (1) second and release
Note: The ICC will attempt to start the unit when the TEST
button is pressed and released
Note: The preferred method of resetting the ICC is to push
the TEST button down for one (1) second.
Optional Condensate Overfl ow Protection
An optional condensate overfl ow protection fl oat switch may
be connected to the Blower control when using the Comfort
Control system.
2
If the optional fl oat switch is open for thirty (30) consecutive
seconds during compressor operation, the ICC will
shut down the compressor to keep it from continuing to
operate, until the fl oat switch has been closed for thirty (30)
consecutive seconds. The dual 7-segment LEDs will fl ash
"c", "C", "h", or "H" while the compressor is shut down due
to condensate overfl ow protection.
