Display message: No contact with outdoor temperature sensor

What does No Outdoor Temp Sensor Contact mean?

The NIBE SMO S40 system cannot detect the outdoor temperature sensor. This will cause the calculated supply temperature to be set to a minimum value, which may affect heating performance.

• Loose or faulty connection to the outdoor temperature sensor
• Damaged outdoor temperature sensor
• Wiring issue in the sensor circuit

Click steps to track your progress.

   If the alarm recurs, you can temporarily adjust the minimum supply line in menu 1.30.4 if a higher temperature is desired.
