Outdoor Ambient Temperature Sensor Error

If not available use heat pump if outdoor.

Outdoor ambient temperature sensor error.

The ambient atc or outside air temperature sensor is an ntc negative temperature coefficient sensor that informs the semiautomatic automatic temperature control system of outside air temperature. System high pressure protection. The series o 4 outside air temperature sensors are great for monitoring ambient air temperatures in outdoor applications. Indoor coil temperature sensor is open or shorted control board sets temp to 40 f.

Unit continues to operate. Outdoor discharge air temperature sensor. Outdoor fan speed has been out of control. Use elec heat if available for heating.
