CONVENTIONAL THERMOSTAT WIRING 3) Locked Rotor • The ICC will display a flashing "L" followed by a flashing "04" when a locked rotor condition occurs. Active Protection - Code L4 - Locked rotor If the ICC detects the compressor has run less than 15 seconds for four (4) consecutive starts during the same call for unit operation, the ICC will lockout the compressor to keep it from continuing to operate and flash a "L" on the dual 7segment LEDs followed by a "04". IMPORTANT: This mode of active protection must be manually reset. 4) Open Start Circuit Lockout • The ICC will display a flashing "L" followed by a flashing "06" when an 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 flash a "L" on the dual 7-segment LEDs followed by a "06". IMPORTANT: This mode of active protection must be manually reset. 5) Open Run Circuit Lockout • The ICC will display a flashing "L" followed by a flashing "07" when an open start 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 flash 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 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 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. 11.11 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 31

3) Locked Rotor
• The ICC will display a flashing “L” followed by a flashing “04” when a locked rotor
condition occurs.
Active Protection – Code L4 – Locked rotor
If the ICC detects the compressor has run less than 15 seconds for four (4) con-
secutive starts during the same call for unit operation, 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 “04”.
IMPORTANT:
This mode of active protection must be manually reset.
4) Open Start Circuit Lockout
• The ICC will display a flashing “L” followed by a flashing “06” when an 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 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 “06”.
IMPORTANT:
This mode of active protection must be manually reset.
5) Open Run Circuit Lockout
• The ICC will display a flashing “L” followed by a flashing “07” when an open start
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 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”.
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 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.
11.11 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
