Where can I buy an Aprilaire outdoor temperature sensor?

Consumer question:

My HVAC contractor installed the Model 600 humidifier in manual mode (without the outdoor temperature sensor). Where can I buy the sensor & wire? What is the model # of the sensor? Are there installation instructions for it and also humidistat controller wiring instructions?

Aprilaires’ response:

Thank you for contacting us regarding the outdoor sensor for your model 600 humidifier. You can contact your installing contractor regarding the installation of the sensor or you can purchase the outdoor sensor from our estore by following the link below:
