    33CS Carrier VVT System Outside Air Sensor Specs

    I was wondering if anyone knows what thermistor type is used for the outside air temperature on a older generation III Carrier VVT system. I am having a hard time with our vendor with locating one.

    Thanks!

    I don't know about the OA sensors, but the room and duct sensors are not thermistors.

    Thank you very much that helps out! I couldn’t find it anywhere in the VVT documentation I had. I appreciate it.
