on the 7-segment LEDs followed by a “6”.
IMPORTANT: This mode of active protection must be manually deactivated.
5) Open Run Circuit Lockout
•
The ICC will display a flashing “L” followed by a flashing “7” 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 7-segment LEDs followed by a “7”.
IMPORTANT: This mode of active protection must be manually deactivated.
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.
