Information About S89C1087
The S89C1087 is part of Honeywell’s S89 Series of hot surface ignition control modules engineered for direct control of gas-fired appliances. It performs a fully automatic ignition sequence by energizing the hot surface igniter, verifying flame presence, and controlling the main gas valve accordingly. Compatible with Norton 201 and 271 igniters, it uses a single rod to both ignite the burner and sense flame presence through rectification. If ignition fails during the 6-second trial period, the module performs a complete gas shutoff and enters lockout mode, requiring a thermostat reset for restart. This single-trial safety design provides dependable protection against unburned gas accumulation. The S89C1087 is compact, easily mountable, and ideal for residential and light commercial systems that demand both safety and ignition precision.
Key Features:
- Single-Rod HSI Control: Combines ignition and flame sensing in one electrode for simplified design and installation.
- 6-Second Ignition Trial: Provides fast burner light-off and immediate safety lockout upon failure to ignite.
- Automatic Gas Shutoff: Ensures complete gas flow interruption after ignition failure, enhancing system safety.
- Thermostat Reset Feature: Lockout clears when thermostat calls for heat again, simplifying operation.
- Flame Rectification Sensing: Utilizes proven electronic detection method for reliable flame verification.
- Wide Temperature Range: Operates from -40°F to +175°F for reliable use in varied environmental conditions.
- Broad Compatibility: Works with natural gas or LP systems and integrates with VR8205/VR8305 gas valves.
- Rugged and Compact Construction: Built for durability and easy installation in confined furnace compartments.
- High Reliability: Solid-state electronics provide consistent performance with minimal maintenance.
- Certified Safety Compliance: Meets CSA and UL standards for residential and commercial heating safety.
The S89C1087 delivers the reliability and precision required for modern gas-fired systems, combining fast ignition control, automatic safety lockout, and dependable flame supervision in one compact module.
