It converts high-voltage line power (120, 208, or 240 VAC) down to a safe 12\/24VAC to energize the system's control board, thermostat circuit, and all low-voltage components. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the system won't respond to any call for heating or cooling, and contactors or relays won't energize.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | 120\/208\/240 VAC primary | 12\/24V secondary | 60 Hz | Single-phase | CSA listed | Factory cross-reference: Totaline HCTY156D0LS11102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized part manufactured to exact VA and impedance tolerances.
