Resideo S8701A1050 Module

The Resideo S8701A1050 Direct Spark Ignition Control Module is an electronic DSI control designed to manage ignition sequencing, flame monitoring, gas control operation, and safety shutdown in compatible gas-fired HVAC and heating equipment.

The S8701A1050 configuration provides a 30-second pre-purge, followed by a 4-second trial for ignition with one ignition trial. It uses a two-rod flame-sensing configuration and includes an alarm terminal. The S8701 control family also incorporates pressure-switch input and fan relay functions as part of the burner operating sequence.

When replacing an existing gas furnace ignition control module, verify the complete part number, wiring terminals, ignition sequence, flame-sensing arrangement, pre-purge requirements, ignition trial timing, and appliance specifications. Terminal arrangements and operating sequences can vary between ignition controls, so replacement should not be determined by physical appearance alone.
