IMPORTANT: This mode of active protection must be manually reset.
Exiting Active Compressor Protection Lockout
Three 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.
12.6 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 active protection lockout mode
2) Bypasses 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” or “C” 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 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.
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 dual 7-segment LEDs will illuminate.
Fault Recall Mode – the top and bottom segments on the right
side are illuminated
• When entering FAULT RECALL mode, the ICC will automatically scroll through
stored faults on the dual 7-segment LEDs.
• Each fault is displayed one time with the top right hand segment of the dual 7-
segment display activated between faults.
• Each fault is displayed with the most recent fault displayed first.
