“SensErr 2” Will appear on display.
The system will continue to operate regardless of the upper limit temperature.
Required actions:
1. Refer to P03 section of the technician settings.
2. Check the temperature value and disable the sensor if needed.
3. Replace the sensor.
The system will continue to operate using constant predefined values.
In addition, the display will alternate between “LO” and -11°F/-24°C
for low temperature readings, and between “HI” and 55°F/13°C for
high temperature readings.

If the system is configured to work with more than 1 snow sensor, the faulty
snow sensor number will appear on display: P01, P02, P03 or P04.
The system will use readings from snow sensor 1 instead of the missing
