York S1-3120A3571 Electric Furnace Sequencer Relay

The York S1-3120A3571 Electric Furnace Sequencer Relay is an essentialcomponent of HVAC systems especially electric furnaces. This is a piece of hardware, constructed from metal and plastic that regulates the sequential operation of heaters in a furnace. Its main function is to maintain accurate time and has an on-and-off cycle varying from 1-160 seconds, thus providing even heat and conserving energy. This sequencer safeguards the electrical system, enhances the durability of furnace parts, and avoids rush currents by switching on the heating elements in turns. This leads to better control of temperature, reduced usage and tear of the system, and even the possibility of saving energy.
