The RM7890A and RM7890B provide microprocessor-based burner control for automatically fired gas, oil or combination fuel single burner applications. Expanded annunciation, remote reset, flame signal strength and other options are available. The RM7890B also contains a self-checking scanner and is recommended for systems which operate for more than 24 hours. The RM7840E provides complete system sequencing for single burner applications. The RM7840E will, upon a heat demand or input from the burner controller, start the burner blower, purge the system and initiate ignition and burner operation. No external purge circuit is necessary. The RM7840E is commonly applied to package burner systems. FRU-1, P.O. Box 90, Lebanon, PA Phone: , Fax: Printed in U.S.A. 06/07
