When the Error Code Display option is ON, an error code
will be displayed when the associated error occurs. Any pre-
vious error codes that occurred when the Error Code Dis-
play was configured OFF will also be displayed.
NOTE: When an error is cleared, any errors remaining in the
bypass controller will be displayed sequentially until all er-
rors are cleared.
When the Error Code Display option is set to OFF, no
error codes will be displayed by the bypass controller. Hav-
ing the Error Code Display turned OFF will not stop the er-
rors (alarms) from being communicated on the network. See
the Alarm Options section on page 18 for more information
pertaining to network alarms.
To configure the Error Code Display option, set category 7,
option 1. Use the left set point buttons to toggle the setting
to ON or OFF. The default is OFF.
System Errors (SE) — System Errors occur when the
zone controller detects a zone operating problem or system
operating problem. See Table 2 for System Errors.

SYSTEM ERROR
DESCRIPTION
ALARM PRIORITY
LEVEL
SE10 IAQ Exceeded Limit 2
IAQ EXCEEDED LIMIT ERROR — The bypass controller
can interface to an indoor air quality switch. If the CO
2
level
exceeds the configurable set point for the configured amount
of time, the bypass controller will issue an SE10. An IAQ
input is considered active only after the contact has been closed
for 2 minutes. Once an IAQ sensor goes active, it is only
considered inactive after the contact has remained open for
4 minutes and 15 seconds to ensure air quality.
Storage Failure (SF) Errors — A Storage Failure er-
ror is an indication that the bypass controller has invalid in-
formation in its memory.
When an SF Error occurs, the bypass controller replaces
the invalid data in memory with factory selected default val-
ues and the invalid information is not used by the associated
system control.
To clear an SF Error, enter correct data at the bypass con-
troller. See Table 3 for a description of Storage Failure
Errors.
