Electric Heat Sequencer with Timed Switching

The White-Rodgers 24A34-2 is a single-switch electric heat sequencer designed for HVAC systems that require staged heating control. It manages the activation sequence for heating elements to prevent electrical overload during startup. This component suits technicians servicing residential or light commercial furnaces and air handlers.

30-90 Second On Delay for Staged Activation

The sequencer provides an on-time delay ranging from 30 to 90 seconds, allowing heating elements to energise in a controlled sequence. This timing window handles standard staging requirements for electric heat kits. It does not support systems needing multiple independent switches, adjustable off-delay settings, or cooling-stage sequencing.

Highlights

  • 1 switch controls electric heat staging
  • 30 to 90 second on timing delays activation

Questions about this item

Will the 24A34-2 sequencer coordinate with my existing furnace control board?

The 24A34-2 provides one switching circuit with a 30-90 second on-time delay, designed to stage electric heat elements in standard residential furnace control schemes.

How can I confirm the 30-90 second delay is operating correctly after installation?

Use a multimeter to measure the time between the control voltage arriving at the sequencer coil and the load contacts closing; it should fall within the 30-90 second window.
