DESCRIPTION
The White Rodgers 50E47 is an automatic gas inter-
rupted ignition control employing a microprocessor to
continually monitor, analyze, and control the proper op-
eration of the gas burner.
rupted ignition control employing a microprocessor to
continually monitor, analyze, and control the proper op-
eration 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.
