Description
The York S1-02424116000 Relay Control is a single-pole double-throw switching relay rated at 24 volts and compatible with both 50 and 60 hertz electrical systems, used to route a control signal to one of two output circuits depending on the relay’s energized or de-energized state. It receives a low-voltage input from a thermostat or control board and switches the output path accordingly, allowing a single signal to regulate two separate operating conditions within the same circuit. Within HVAC systems, this relay directs control signals between heating and cooling modes, fan sequencing, or auxiliary load changes.
