Resideo S87B1024 Ignition Module
The Resideo S87B1024 is a robust Direct Spark Ignition (DSI) module engineered to provide reliable electronic control of gas-fired heating systems. Operating on a 24 Vac ignition circuit, this unit is designed for Natural or LP gas applications where a single rod flame sense configuration is required. This specific model features a single trial for main burner sequence; if ignition is not established within the 21 second ignition trial time, the system enters a 100% shutdown and safety lockout. The .8 second flame failure response time ensures rapid closure of the gas valve upon loss of flame signal, maintaining stringent safety standards. Without a prepurge cycle, the S87B1024 ignition controller is ideal for atmospheric burners or power-vented applications where immediate spark is necessary. Its integrated alarm terminal provides clear diagnostic feedback to the contractor, simplifying troubleshooting during service calls in the field.
Key Benefits
- Broad Compatibility: Functions seamlessly with both Natural Gas and Liquid Propane HVAC systems.
- Rapid Flame Detection: Features a high-speed .8 second response time to mitigate gas buildup during flame outages.
- Simplified Diagnostics: Includes a dedicated alarm terminal for remote notification or localized troubleshooting of lockout conditions.
- Rigid Safety Logic: The 21 second lockout timing provides a definitive window for ignition before securing the system.
- Durable Construction: Built by Honeywell Home / Resideo to withstand the high-temperature environments typical of furnace and boiler cabinets.
Common Questions
Can the S87B1024 be used in systems requiring prepurge?
No, this specific module is designed with no prepurge timing. For applications requiring a combustion blower to clear the heat exchanger prior to ignition, a different S87 series variant must be selected.
Does this module support dual-rod flame sensing?
This unit is specifically calibrated for single rod flame sense, where the spark igniter and flame sensor share a common probe. It is not compatible with remote or dual-rod configurations.
What happens if the burner fails to light after the 21-second trial?
The module will immediately go into safety lockout. To reset the device, the 24V power must be interrupted, typically at the thermostat or the main system transformer.
