Description
The Supco Q111 DPST Sequencer 24V is a control component used to manage the timed activation and shutdown of electrical heating parts and blower motors in staged heating systems. It operates by sequentially closing and opening, two sets of contacts, allowing components to connect in a controlled order rather than all at once. In this applications, it is commonly installed in the electric furnaces, heat pumps, and gas or oil heating systems to regulate heat output and airflow timing. Within HVAC systems equipment, it support to coordinate system startup sequences, reduce electrical load spikes, and ensure stable, safe operation of heating cycles.
