The White Rodgers 50E47 is an automatic gas interrupted ignition control employing a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner. Signals interpreted during continual surveillance of the thermostat and flame sensing element initiate automatic ignition of the burner, sensing of the flame and system shut-off during normal operation. System fault analysis, which quickly shuts off the gas flow, coupled with automatic re-ignition upon sensing a fault correction, highlight the control’s capabilities.
