The York S1-024-19082-740 is an OEM 24V heat sequencer relay engineered for use in York electric heating systems. Heat sequencer relays are essential components in electric furnaces and air handlers, providing staged activation of heating elements to prevent voltage spikes, reduce electrical demand, and extend the life of heating components.
How It Works
This relay responds to a 24-volt control signal from the system thermostat, sequentially energizing electric heating elements in a controlled, time-delayed manner. By staging element activation rather than switching all elements simultaneously, the sequencer protects electrical circuits and ensures smooth, efficient heating operation.
