    White Rodgers 21M51U-843 Ignition Module/Circulator Furnace Control Kit with Nitride Ignitor, 24 VAC

    Emerson Climate Technologies, the parent company of White Rodgers, is an industry leader in delivering business-advancing and industry-revolutionizing innovations. Their strive to help individuals and companies meet the challenges of change and the demands of adaptability has made Emerson a globally renowned force that drives HVACR technology. Being involved in industry aspects such as system controls, thermostats, valves, sensors, transformers and relays, indoor air quality products, and accessories, the experience and expertise provided by Emerson is second to none. Their products are specifically engineered to be accurate and optimize your systems to result in the most efficient performance possible. Over the last 75 years, White-Rodger's dedication for taking proven mechanical controls and enhancing them by integrating them into residential equipment applications through applied electronics has profoundly changed the way users experience comfort and convenience. Their dream to increase system reliability and communications has become a reality by integrating it into the manufacturing process for all their products. Their goals of becoming an incredibly easy company to do business with, expanding their technology leadership position, using broad capabilities in products and services to manufacture unique, high-quality solutions to practical problems, being the best value provider for products and services, and maintaining a work environment where people and ideas flourish together has made them one of the most highly sought after companies by industry professionals such as engineers, contractors, installers, specifiers, architects and consumers within the HVAC industry.

    The 50M51-843 is a universal replacement control for two-stage automatic gas ignition controls employing a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner and inducer. The 50M51-843 controls a multiple tapped induction circulation blower. Signals interpreted during continual surveillance of the twostage thermostat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shutoff during normal operation. The control incorporates system fault analysis for quick gas flow shutoff, coupled with automatic ignition retry upon sensing a fault correction. The 50M51-843 quickly and easily replaces White-Rodgers 50M51-XXX controls. This kit includes: a 50M51-843 Ignition Control Module, a 21D64-2 Ignitor Kit.
