The 50M56-743 kit is an automatic gas HSI Integrated Furnace 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.
These controls incorporate system fault analysis for quick gas
flow shut-off, coupled with automatic ignition retry upon sensing
a fault correction.
