Carrier 4-zone Controller

Post by Conrad » Wed Oct 26, 2011 2:00 pm

We have a Carrier 4-zone Controller installed in a Villa, Power supply on main Controller Board was switched off and on. But unit did not come back to operational status and no error codes display on the interface board. Can you help please.
