Outdoor Ambient Temperature Sensor Error

The sensor detects an abnormally low or high coil temperature.

Outdoor ambient temperature sensor error.

Open circuit or short circuit of compressor discharge temperature sensor t5. Check unit placement if the outdoor unit is in a high temperature area wait until the ambient. The sensor detects an abnormally low or high outdoor ambient temperature. The computer uses this input along with other in car temperature.

F1 ol 2 time tl on outdoor ambient temperature sensor t4 open circuit or short f2 ol 3 time tl on circuit. Outdoor fan speed has been out of control. 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. Unit continues to operate.

Fan speed out of control. The temperature sensors are mounted in a nema 4x enclosure with integral mounting tabs. Compressor discharge high temperature protection. 43 communication failure with unit a 44 communication failure with unit b 45 communication failure with unit c 46 communication failure with unit d 47 unit a freeze protection 48 unit b freeze protection.

Inverter module igbt over strong current protection. Outdoor ambient temperature sensor malfunction. Outdoor ambient temperature sensor open circuit or short circuit. 24 installation and maintenance service manual 14 18k.

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. Outdoor discharge air temperature sensor. Open circuit or short circuit of outdoor ambient temperature sensor t4.

Out unit low side value temperature sensor t2b open circuit or short. System high pressure protection. Overvoltage or too low voltage protection. Open or short circuit of indoor room or evaporator temperature sensor.

Outdoor coil temperature sensor is open or shorted sets temp to 20 f. Outdoor mid coil temperature sensor malfunction. Cooling oil return cycle. Open circuit or short circuit.

System low pressure protection. Use elec heat if available for heating. Condenser coil temperature sensor t3 open circuit or short circuit. The mounting tabs can be used to surface or suspension mount the temperature sensors.

Check sensor is installed correctly on control. The ntc sensor s resistance decreases as the outside air temperature increases. If not available use heat pump if outdoor. Outdoor unit eeprom error.
