Product Overview

The ST9103 electronic fan timer integrates control of all burner and circulator fan operations in an oil furnace. This replacement control features a central wiring point for most of the electrical components in the furnace, making installation easier in multiple systems. The basic purpose of the ST9103 electronic fan timer is to monitor the thermostat for heat, cool, and fan demands while running the oil burner primary control—and up to a two-speed circulating fan—as required. This model also monitors a limit switch string, which energizes the circulating fan whenever the limit switch opens.
