Ignition Control Modules

Ignition control modules manage the ignition sequence in heating equipment used by HVAC technicians, facility maintenance teams, and commercial service professionals. This category includes direct spark, pilot relite, intermittent pilot, hot surface ignition, and integrated furnace controls with defined timing, rod configurations, diagnostics, and connection features for compatible heating-system service and replacement work.

How to Choose an Ignition Control Module

Start by matching the ignition method and rod configuration required by the heating equipment. Then compare trial and lockout timing, available installation space, and the diagnostic, wiring, flame-sensing, or fan-control features relevant to the replacement.

Use Cases

Support heating-system ignition service

These controls are used by HVAC and maintenance professionals working on compatible heating equipment with direct spark, pilot relite, intermittent pilot, or hot surface ignition.

How to Choose

Match the control sequence

Confirm the ignition type, single- or two-rod configuration where applicable, and required trial and lockout timing before selecting a module.

Applications

Plan for the equipment function

Choose an integrated furnace control when the application also requires connections for cooling, low heat, and high heat fan operation; otherwise, select the ignition-control type suited to the equipment.

Additional Info

Review service and fit details

Compare overall dimensions, terminal or wiring options, flame-sensing compatibility, LED indicators, and included components when those features are needed for the installation.

Planning Guide

Plan the right fit before choosing

Ignition Type

Select the control style used by the equipment

The category includes several ignition-control approaches for compatible heating equipment. Direct spark controls are available in single-rod and two-rod configurations. Other options include pilot relite controls, intermittent pilot controls, universal hot surface ignition modules, and integrated furnace controls.

  • Pilot relite control produces a spark pulse until flame is sensed and restarts sparking when flame goes out.
  • Intermittent pilot control supports one- or two-rod configurations.
  • Universal hot surface modules offer variable timing selection and direct or indirect flame sensing.
  • Integrated furnace controls combine hot surface ignition control with dedicated fan-speed connections.
Timing and Configuration

Match timing and rod requirements

Direct spark models have stated trial and lockout periods that should align with the required ignition-control sequence. Available examples include 4-second, 6-second, 11-second, and 21-second timing. An intermittent pilot model offers selectable 15- or 90-second timing.

  • Single-rod and two-rod direct spark configurations are represented.
  • Direct spark trial and lockout periods are offered in matching 4-, 6-, 11-, and 21-second examples.
  • Intermittent pilot timing can be selected at 15 or 90 seconds.
  • A pilot relite module continues sparking until flame is sensed.
Installation and Service Features

Compare fit, wiring, and diagnostic needs

Measure the available space and review the connection and service features needed for the replacement. Listed compact controls range from 4.1 to 4.5 inches wide, 5.8 to 6.3 inches deep, and 2.25 to 3.4 inches high. Some controls add visual diagnostics, quick-connect wiring options, or specialized output connections.

  • A spike terminal output is available on a 24V pilot relite module.
  • A universal hot surface module includes a tri-colored LED diagnostic indicator.
  • An integrated furnace control has LED fault diagnostics, fault recall information, nine wiring harnesses, and a replaceable 3A fuse.
  • The integrated furnace control includes a universal nitride ignitor kit.
