Lennox International Inc. LB-83114C is a solid-state defrost replacement board for use with HP7-1, -2, HP8, CliP9, and CliP10 series heat pumps. It provides automatic switching from normal heating operation to defrost mode and back. The board contains a solid-state timer which switches an external defrost relay through 1/4" male spades mounted on the board's circuit board. The control energizes the defrost relay at regular timed intervals. A factory installed jumper on the circuit board connects terminal W1 on the circuit board to one of the three timing pins, providing a choice of 30, 60, or 90-minute defrost intervals.
