If the ICC detects current in the start circuit without current present in the run cir-
cuit, , the ICC will lockout the compressor to keep it from continuing to operate
and flash a “L” on the dual 7-segment LEDs followed by a “07”.

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
N No otte e:: The preferred method of resetting the ICC is to push the TEST button down
for one (1) second.
12.5 Test and Fault Recall Modes
T Te es stt M Mo od de e ((T Te es stt B Bu utttto on n o on n tth he e IIC CC C))
• Enter TEST mode by pressing the TEST button with an insulated probe for one
(1) second and release.
• The TEST mode causes the ICC to do the following
1) Resets the ICC from any active protection lockout mode
2) Resets the 3-minute anti-short cycle timer
3) Energizes the unit without a command for unit operation
• If the 3-minute anti-short cycle timer or 30 second minimum run timer is active (a
flashing “c”, “C”, “h”, or “H” is displayed on the dual 7-segment LEDs) and a com-
mand for unit operation is present, TEST mode causes:
1) A “t” to display momentarily on the dual 7-segment display
Lower case “t”
2) The compressor will start and the outdoor fan will operate
3) The display will change to a steady “c”, “C”, “h”, or “H” to show the current
command for unit operation.
Note: If a command for unit operation is present at the end of TEST mode, the
unit will continue to operate.
• If no command for unit operation is present, TEST mode causes
1) A steady “t” appears on the dual 7-segment LEDs
2) The compressor will start
3) The compressor will turn off after 5-seconds.
Note: Entering TEST mode without a command for unit operation will cause the
compressor to run 5-seconds.

• Enter F FA AU UL LT T R RE EC CA AL LL L mode by pressing the T TE ES ST T and S SW W2 2 buttons at the
same time with insulated probes for one (1) second and release.
• When entering and exiting FAULT RECALL mode the top and bottom segments
of the dual 7-segment LEDs will illuminate.
Fault Recall Mode – the top and bottom segments on the right
side are illuminated
• When entering F FA AU UL LT T R RE EC CA AL LL L mode, the ICC will automatically scroll through
stored faults on the dual 7-segment LEDs.

13.X Test and Fault Recall Modes
Test Mode (Test Button on the ICC)
•
Enter TEST mode by pressing the TEST button with an insulated probe for one (1) second
and release.
•
The TEST mode causes the ICC to do the following
1)
Resets the ICC from any active protection lockout mode
2)
Resets the 3-minute anti-short cycle timer
3)
Energizes the unit without a command for unit operation
•
If the 3-minute anti-short cycle timer or 30 second minimum run timer is active (a flashing
“c”, “C”, “h1”, or “h2” is displayed on the 7-segment LEDs) and a command for unit
operation is present, TEST mode causes:
1) A “t” to display momentarily on the 7-segment display
Lower case “t”
2) The compressor will start
3) The display will change to a steady “c”, “C”, “h1”, or “h2” to show the current command
for unit operation.
Note: If a command for unit operation is present at the end of TEST mode will cause the unit
to continue to operate.
•
If no command for unit operation is present, TEST mode causes
1)
A steady “t” appears on the 7-segment LEDs
2)
The compressor will start
3)
The compressor will turn off after 5-seconds.
Note: Entering TEST mode without a command for unit operation will cause the compressor
to run 5-seconds.
Fault Recall Mode (TEST and SW2 Buttons)
•
Enter FAULT RECALL mode by pressing the TEST and SW2 buttons at the same time
with insulated probes for one (1) second and release.
•
When entering and exiting FAULT RECALL mode the top and bottom segments of the 7-
segment LEDs will illuminate.
Fault Recall Mode – the top and bottom segments illuminated
•
When entering
FAULT RECALL
mode, the ICC will automatically scroll through stored
faults on the 7-segment LEDs.
•
Each fault is displayed one time with the top segment of the 7-segment display activated
between faults.
•
Each fault is displayed with the most recent fault displayed first.
