Comms Check 

This sensor self-check tests the  communication between the control unit and a 
selected sensor 

automatically and should show ‘OK’ at no loss.

  

If this test fails, check the wiring between the control unit and the sensor. Check 
the address and comms settings on the sensor and control unit. If the problem 
persists, refer to
