Outdoor Ambient Temperature Sensor Error

System high pressure protection.

Outdoor ambient temperature sensor error.

The sensor detects an abnormally low or high coil temperature. Outdoor unit eeprom error. Unit continues to operate. If not available use heat pump if outdoor.

Open circuit or short circuit. Open or short circuit of outdoor ambient or condenser temperature sensor. Outdoor discharge air temperature sensor. Use elec heat if available for heating.

Overvoltage or too low voltage protection. The ntc sensor s resistance decreases as the outside air temperature increases. The sensor detects an abnormally low or high outdoor ambient temperature. Outdoor fan speed has been out of control.

Outdoor ambient temperature sensor malfunction. Indoor coil temperature sensor is open or shorted control board sets temp to 40 f. System low pressure protection. The mounting tabs can be used to surface or suspension mount the temperature sensors.

24 installation and maintenance service manual 14 18k. The temperature sensors are mounted in a nema 4x enclosure with integral mounting tabs. Open circuit or short circuit of compressor discharge temperature sensor t5. 84 outdoor ambient temperature fault.

Compressor discharge high temperature protection. Open circuit or short circuit of outdoor ambient temperature sensor t4. Check unit placement if the outdoor unit is in a high temperature area wait until the ambient. F1 ol 2 time tl on outdoor ambient temperature sensor t4 open circuit or short f2 ol 3 time tl on circuit.

Outdoor mid coil temperature sensor malfunction. Check sensor is installed correctly on control. The computer uses this input along with other in car temperature. Cooling oil return cycle.

Outdoor ambient temperature sensor open circuit or short circuit. 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. The series o 4 outside air temperature sensors are great for monitoring ambient air temperatures in outdoor applications. Inverter module igbt over strong current protection.

Fan speed out of control. Out unit low side value temperature sensor t2b open circuit or short. Open or short circuit of indoor room or evaporator temperature sensor. Outdoor coil temperature sensor is open or shorted sets temp to 20 f.
