Communication Fault Continues:

 

 
# Disconnect the supply power & check the 

continuity

 of the COM-U wire from the following 

points:  

 

COM-U terminal point on the indoor PCB. 

 

To the communication terminal points on the indoor terminal block. 

 

To the communication terminal points on the outdoor terminal block. 

 

To the COM-U terminal point on the outdoor PCB. 

 

Note: 

When checking the 

continuity

 between the indoor terminal block & the outdoor terminal 

block, disconnect the COM-U & Active wires on the indoor terminal block, and then attach them 
together. This will create a 

circuit

 that can then be tested between the COM-U & Active terminal 

points on the outdoor terminal block.

 

COM-U terminal point on indoor PCB. 

 

Communication terminal points on 

indoor terminal block. 

 

Communication terminal points on outdoor 

terminal block. 

 

COM-U terminal point on outdoor main PCB.
