Product Information Run a furnace and other HVAC systems continuously and smoothly with the Universal Integrated Ignition Fan Control (50A55-843). The 50A55 series unit is designed and constructed by White-Rodgers. It's a multi-functional controller that monitors the integrity of motors and maintains motor operational efficiency. The White Rodgers unit has a well-engineered design that helps to facilitate easy installation in a furnace and other HVAC units. Technicians will be pleased by the reliable heat and air controls enabled by the Universal Integrated Ignition Fan Control. The White-Rodgers control unit measures 8 by 5 by 2.5 inches and weighs 12.8 ounces. Its frame is constructed of plastic, which makes the unit both lightweight and durable. It is designed for a furnace with a silicon carbide ignitor as well as other HVAC systems. The board utilizes a microprocessor that acts as a central controller. The White-Rodgers modules can operate various brands of furnace, ventilation, air conditioning, and humidifier units via provided terminals. The board design allows the microprocessor to monitor systems so that environments remain stable in varying climates and seasons. It has a designated input voltage of 25 volts AC at 50/60 Hz and a maximum current of 25 VAC: 0.45 AMP. The control unit’s valve relay runs at 1.5 AMP. The ignitor relay runs at 6 AMP 120 VAC 50/60 hertz. Its 25-watt power supply is connected via a 0.25-inch Quick Connect 12-pin interface. With these specifications, the control module utilizes power efficiently. It is designed to operate between a temperature range of -40 to 175 degrees Fahrenheit in a furnace or air conditioner. It can also tolerate a humidity range of between 5 and 93 percent. As such, the unit can be relied on to operate as expected in hot, cold, and dry conditions. For installation and troubleshooting motor failures, a flash code diagnostic system is equipped on the control board. This allows technicians and homeowners to read
