Issue:

Heat Fail Diagnostic

Resolution:

Heat Fail is a Priority 2 CCP diagnostic. From VAV-SVU01A-En page 58:

Indicates the Voyager has tripped the high temperature limit switch (TCO2). This alarm occurs on gas heat units only.

This property indicates the active status of the diagnostic. This diagnostic is present when either of the high temperature limit switches on a gas heat unit is open. When these limit switches open, a high temperature condition exists. This input is valid on all units with gas heat. This is an auto reset diagnostic. 0=NORMAL, 1=FAIL
