play items are shown below. The values in parentheses
are the possible displays.

Line 2 General Unit Status
Line 3

Unit Type = VAV (CV, VAV, Flexsys)

Line 4 Status = NORMAL (TROUBLE, ALARM)

Unit Type will be determined from the “Unit Type”
con

Þ

g u ra tion setting un der the Con

Þ

guration menu and

unit), CV (constant volume unit), or Flexsys.

Status is determined by:
• NORMAL - no faults have been detected
• TROUBLE - a fault that does not cause unit shut-

down has been

detected
• ALARM - a fault that causes the unit to be shut

down has been detected

Refer to the section on Service and Troubleshooting for
