The Honeywell EC7830A or EC7850A series automatic burner controls are microprocessor-based burner controls for gas, oil or combination forced-air burners with modulation (EC7850A) or ON/OFF burner operation (EC7830A). The automatic burner controls of the EC7830A and EC7850A SERIES can be supplemented with substructures, different amplifiers and purge cards. The system has a modular design. The optional data display module can be mounted directly on the automatic burner control unit or on the front of the control cabinet door. If permitted in the respective application area, the data display module can also be mounted externally. The SERIES 7800 includes the following functions: automatic burner sequence control, flame monitoring, system status display, system and self-diagnosis and troubleshooting.
