The 50A65-843 Universal Nitride Integrated Ignition module is an automatic ignition control that employs a microprocessor that continually monitors, analyzes, and controls the proper operation of the gas burner, inducer, and fan. The 50A65-843 is unique because it incorporates a patented adaptive algorithm routine that uses an 80V nitride ignitor to ensure the most effective ignitor temperature, increasing the life expectancy of the ignitor.This one module will replace all of the 50A65-XXX integrated ignition nitride modules that have been manufactured by White-Rodgers. The Universal Module has an extensive cross reference for replacement and includes additional jumper wires, additional wiring harness, a jumper for Trane applications and a 3/16†terminal for Lennox (only). The module also has terminals for powering a humidifier and an air cleaner.
