What does COMMBOX error code “SensErr 1” mean?
Error 1 “SensErr 1” will appear when there is a communication error with one (or more) snow sensors.
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 readings from the faulty snow sensor.
