the 100111778 circuit board utilizes a robust architecture to manage communication between the user interface and mechanical components like the blower and gas valve

What is the purpose of the 3-inch thermostat

While some heat tinting is expected

It is designed for line-voltage circuits and is not compatible with standard 24V residential transformers

Swapping an auto-reset limit for a manual reset (or vice versa) can alter the safety sequence and diagnostic behavior of the digital control board
