Part number \u003cstrong\u003eHT01AW229\u003c\/strong\u003e, this 60VA transformer steps down the 115\/208\/230V line voltage to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control circuitry. When this transformer fails, the entire control circuit goes dead — your thermostat goes blank, the system refuses to respond to any commands, and you may measure zero voltage on the 24V secondary terminals. Replacing it with the correct OEM unit restores full system operation immediately.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA power rating | 115\/208\/230V AC primary (multi-tap) | 24V AC secondary | 50\/60 Hz | Foot-mount configuration | Factory part number HT01AW229 \/ HT01AW229A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA ratings and insulation class.
