Description

Product Overview

The Gulfmew 24A34-3 Electric Heat Sequencer is engineered for precise control of heating elements and blower motors in a variety of HVAC and industrial heating applications. Housed in a rugged 2.56 x 2.17 x 1.77 inch enclosure weighing just 2.56 ounces, this 24 V sequencer features dual DPST (double pole single throw) contacts that allow independent control of two circuits. Its design incorporates quick‑connect terminals for fast wiring, and a multi‑position mounting system that accommodates horizontal, vertical, or angled installations, ensuring flexibility in tight spaces. The unit supports on‑timings from 1 to 20 seconds and off‑timings from 40 to 110 seconds, providing granular control over heating stages to improve efficiency and extend component life. Compatibility with part numbers such as Q103, 33244, 33844, HQ1056789, HN67QC005, ZC24A34-3, and many others makes it a direct replacement for a wide range of legacy sequencers.

Usage

This sequencer excels in environments where reliable temperature regulation and fan coordination are critical. Typical installations include residential and commercial furnaces, oil‑ and gas‑fired heating systems, electric heat pumps, and industrial process heaters. By staging heating elements in a controlled sequence, the device reduces peak power draw, minimizes thermal shock, and promotes even heat distribution. It is also suitable for use in laboratory equipment, greenhouse climate control, and any application that requires synchronized fan and heater operation. The compact size and versatile mounting options allow technicians to install the sequencer in confined panels, control cabinets, or directly onto heat exchangers, making it an ideal solution for retrofit projects and new builds alike.
