What does the first stage of most electric heat sequencers in residential furnaces turn on?

In residential electric heating systems, the first stage of a sequencer is designed to manage the operation of heating elements and components efficiently. This is essential for preventing excessive electrical load and ensuring seamless heating.

When the first stage of the sequencer is activated, it typically initiates the heating cycle by engaging the first stage of the heating elements. In many systems, this first stage may also include the activation of the blower motor. The reason for this dual activation is to ensure that as soon as the heating elements begin to warm up, the blower motor is running to distribute the heat throughout the living space. This prevents the buildup of heat within the furnace and promotes more efficient heating.

By turning on both the first stage elements and the blower motor, the system optimizes performance and improves comfort levels in the home. The ability to manage these components together allows for a more balanced and responsive heating system, contributing to the overall effectiveness of electric heating solutions in residential settings.
