S1-50T35-743 White Rodgers 50T35-743 Silicon Carbide Integrated Ignition Control

The 50T35-743 is an automatic gas interrupted ignition control that employs a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner, inducer, and fan. 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. This control incorporates system fault analysis for quick gas flow shut-off, coupled with automatic ignition retry upon sensing a fault correction. Features: Includes flash code diagnostics. Twinning. Includes mounting hole template. Fused to protect low voltage system transformers. Adjustable blower relay. 90+ furnace option.
