These lights indicate various circuit board functions:
LED 2 = When illuminated, indicates the relay panel is energized.
LED 3 = When illuminated, indicates the microprocessor has energized relays 1, 2, and 3.
LED 4 = When illuminated, indicates the microprocessor has energized relays 4, 5, and 6.
LED 5 = When illuminated, indicates the microprocessor has energized relays 7, 8, and 9.
LED 6 = When the CCRP is energized, this light should illuminate, either in a flashing or a continuous illumination mode, indicating the microprocessor is processing information.
-
No Illumination: Microprocessor is unable to process information. Check system wiring.
-
Continuous Illumination: Will occur any time a peak control signal is being received.
-
Slow Flash (4 second duration): Will occur during off-peak times. The illumination time of the light is in direct relation to the temperature information the CCRP is receiving from the outdoor temperature sensor. A long illumination time indicates warmer temperatures and a short illumination time indicates colder temperatures.
