A password is required to access any menus that allow the user to make changes to
the Monitor operation. Password protected menu items include; Diagnostic Tests,
Set-Up Wizards, Custom Setup and Factory Setup.
The factory default password is 1234. This password will give the user access to
Diagnostic Tests

Custom Set-Up
. You may change the

There is a password lockout function that resets fifteen minutes after the keypad is

touched for fifteen minutes, the user will have to re-enter the password to proceed.
Verify Functionality Using Diagnostic Alarms
Diagnostic Alarms
The Diagnostic Alarms are used to provide diagnostic information on the
performance of the product, and to alert the user to a possible malfunction.
Following is a description of the Diagnostic Alarms that are available in the IAQ-TEK.
Low Flow Alarm
The Low Flow Alarm is used to alert the building operators that the intake volume
has fallen below the minimum acceptable level. The basis of the alarm shall be the
result of the Balancer Adjusted CFM (BCFM). The Low Flow Alarm set point is user
established and stored in a register in nonvolatile memory. The default value shall
be 0 CFM. Should the air volume fall below the low volume alarm limit, the alarm
delay timer shall activate. Should the alarm condition persist longer than the time
period established by the alarm delay timer, the low volume alarm will toggle to
ALARM. To reset to a NORMAL condition, the air volume must rise to a value that is
ten percent higher than the Low Volume Alarm Limit. Once this threshold has been
crossed, the alarm process is reset automatically.
Reverse Flow Alarm
The Reverse Flow Alarm is used to alert the building operators that the airflow is
blowing out of the intake to the air handler. No deadband shall apply to this alarm.
Should the alarm condition persist longer than the time period established by the
alarm delay timer, the reverse flow alarm bit shall toggle to 1 or ALARM. To reset to
a NORMAL condition, the pressure must increase from a negative value to zero or
have the sign change to positive. Once this threshold has been crossed, the alarm
process is reset automatically.
