Description
The Reznor RZ259780 Sequencer/Time Delay Relay is an electrical timing unit that controls staged activation of heating components by switching contacts after a preset delay. It is used in electric heaters and furnace models of HVAC systems, where it sequences multiple heating elements to reduce inrush current and manage load distribution during startup. This relay operates through a thermal or electronic timing mechanism that energizes contacts in a controlled order. Integrated in the control circuit, it coordinates staged power delivery to heating elements for smoother system startup and balanced electrical demand.
