Similar to the other versatile White-Rodgers universal controls, the 50E47U-843 replaces 325+ part modules for HSI modules, whether you’re working with 24v, 120v, or 240v ignitors. You can use this universal HSI module in all sorts of gas-fired heating appliances, including gas furnaces, pool heaters, boilers, and laundry equipment. It controls and receives inputs from all required components, including inducer fan motors, flame rods, pressure switches, and ignitors, with an easy-to-install harness. You can transfer your old wiring connections before removing your old module.
Along with some of the other White-Rodgers universal furnace controls, you can program and diagnose the 50E47U-843 offline furnace control (and without having power to the module!) using the White-Rodgers Connect App, which uses NFC technology. You can select from several preloaded OEM settings in-app to program the module before installation. This module also displays the real-time flame current (DC microamps), which will give you an idea of how the flame rod and board are working together during diagnosis.
