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”.
IIMMPPOORRTTAANNTT::
This mode of active protection must be manually reset.
EExxiittiinngg AAccttiivvee CCoommpprreessssoorr PPrrootteeccttiioonn LLoocckkoouutt
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
NNoottee::
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
TTeesstt MMooddee ((TTeesstt BBuuttttoonn oonn tthhee IICCCC))
• 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.
FFaauulltt RReeccaallll MMooddee ((TTEESSTT aanndd SSWW22 BBuuttttoonnss))
• Enter
FFAAUULLTT RREECCAALLLL
mode by pressing the
TTEESSTT
and
SSWW22
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
FFAAUULLTT RREECCAALLLL
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.

2) The compressor will start
3) The display will change to a steady “c”, “C”, “h1”, or “h2” to show the current command
