Information About ST9120C-2010

The ST9120C-2010 is a furnace control board developed by Honeywell to manage blower speeds, inducer operation, and accessory loads in residential HVAC systems. It is built to accommodate high starting and running currents, with clearly defined FLA and LRA ratings for motors operating at 120 VAC and 240 VAC. The board features dedicated terminals for an electronic air cleaner and humidifier, each supporting standardized accessory loads for system integration. Typical applications include gas furnace installations requiring coordinated blower control, inducer activation, and accessory support within a low-voltage HVAC control architecture.

Key Features

  • High-load blower support: Rated for up to 15 FLA / 30 LRA at 120 VAC and 7.5 FLA / 15 LRA at 240 VAC.
  • Inducer motor compatibility: Handles 3 FLA / 10 LRA at 120 VAC and 1.5 FLA / 5 LRA at 240 VAC.
  • Accessory terminals: Provides 0.8A support at 115 VAC for both humidifier and electronic air cleaner.
  • Low-voltage operation: Runs on 18–30 VAC for thermostat and ignition interface.
  • Versatile HVAC integration: Suitable for a wide range of forced-air furnace applications.
  • Precision load handling: Multiple FLA/LRA ratings ensure correct pairing with blower and inducer motors.
  • Electronic air cleaner support: Built-in control for EAC devices up to combined 0.8A load.
  • Reliable construction: Honeywell design ensures stable long-term HVAC system performance.

The ST9120C-2010 delivers the reliability and precision required for efficient furnace blower, inducer, and accessory control.
