Understanding this role underlines how essential sequencers are to your HVAC’s ability to adapt and function efficiently. Whether in an electric furnace or a heat pump, a well-functioning sequencer is essential.

How Do Heat Sequencers Work?

Heat sequencers operate through a bimetallic strip that responds to electrical current. When your thermostat calls for heat, the strip heats up, bending to close circuits one at a time. This action powers the heating elements gradually, preventing an immediate surge in power demand.

Here’s a simplified breakdown:

1. Thermostat signals the sequencer.
2. Bimetallic strip heats and bends.
3. Electrical circuits close in sequence.

As the sequencer functions, it regulates which heating elements turn on first, and the delay between each activation. This staged process ensures an even distribution of electricity, avoiding circuit overload.

The sequencer also works with blower fans, timing their operation to align with heating needs. By coordinating element activation and air distribution, sequencers help maintain indoor comfort levels efficiently.

However, a malfunctioning sequencer can disrupt this sequence, causing elements to power up incorrectly. This can lead to uneven heating, increased energy use, or even damage.
