Sporlan Controls 402010 Universal Hot Surface Ignition Module, 24 Vac

Description

The Sporlan Controls 402010 is a Universal Hot Surface Ignition (HSI) Module engineered for reliable, precise ignition control in a wide range of residential and light commercial heating applications. Designed to operate at 24 Vac, this module delivers consistent ignition performance with built-in safety and flexibility to suit diverse system configurations.

Key Features

• 24 Vac operating voltage for broad compatibility with standard heating systems
• 1.5-second flame failure response time for rapid, safe shutdown upon loss of flame signal
• 32-second prepurge cycle to clear combustion chamber before ignition attempt
• Trials for ignition and trial time configurable via dip switch selection — no rewiring required
• Compatible with both Natural Gas and LP (Propane) Gas fuel types
• Supports Single Rod or Two Rod flame sensing configurations
• Universal design simplifies replacement across multiple OEM platforms

Ignition & Safety Control

The 402010 module’s 1.5-second flame failure response time ensures the system shuts down quickly and safely if the burner flame is lost, protecting equipment and occupants. The 32-second prepurge interval purges residual gases from the heat exchanger before each ignition sequence, reducing the risk of uncontrolled combustion events.

Flexible Configuration via Dip Switch

One of the standout features of this module is its dip switch-selectable ignition trial count and trial timing. Technicians can configure the number of ignition attempts and the duration of each trial directly on the module — eliminating the need for separate components or field wiring changes. This makes the 402010 an ideal universal replacement module for a wide variety of furnace and heating system brands.

Fuel & Sensing Compatibility

• Natural Gas and LP Gas compatible — no conversion kit required
• Single rod flame sensing for standard installations
• Two rod flame sensing for systems requiring separate ignitor and sensor electrodes

Ideal Applications

• Residential gas furnaces
• Light commercial heating equipment
• Hot surface ignition system upgrades and replacements
• Multi-brand OEM replacement scenarios
