Why Use a Heat Sequencer Relay?
In electric furnaces and heat strips, energizing all heating elements simultaneously draws a massive inrush of current. A heat sequencer relay staggers element activation over a timed interval, spreading the electrical load and protecting both the equipment and the building’s electrical system. Replacing a faulty sequencer restores proper staged heating, eliminates cold spots, and prevents premature component failure.
Compatibility
- Designed for use with York heating systems and equipment
- Consult your equipment’s wiring diagram and service manual to confirm fitment before installation
Installation Notes
Always disconnect power before servicing. Refer to the original equipment wiring diagram for proper terminal connections. This relay is intended for installation by qualified HVAC technicians in accordance with all applicable local codes and manufacturer guidelines.
