Bosch Outdoor Coil Temperature Sensor T3 (part number 8733953173) is an OEM probe that monitors outdoor coil temperature on Bosch condensing and heat pump units, supplying feedback used for discharge-temperature protection, outdoor fan control in cooling, and defrost control in heating. It enables accurate system protection and dependable defrost sequencing during maintenance. The T3 functions are documented in the Bosch IDS 2.0 service manual; I could not find an official Bosch North America page listing part number 8733953173. (bosch-homecomfort.com)
