3.5 Saving and Restoring Setpoint
Parameters
Upon initial start-up the system operates using the setpoints
programmed by the factory (primary setpoints) as the operating
setpoints. As described in Section 3.4, new operating
parameters may be entered in the Control menu anytime and the
system will then operate accordingly. The new setpoints may be
stored in the Service>Save Cfg>Customer Save menu screen.
The primary setpoints entered by the factory still remain stored
in the controller's memory as the Factory setpoints.
At any time, setpoints for the system may be re-adjusted to any
value and the system will operate accordingly. If it becomes
necessary however, the Service>Save Cfg menu may be
entered and the setpoints to the saved Customer operating
setpoint values may be restored. The original Factory (primary)
setpoint values may also be restored from the Service menu.
Whichever setpoints are restored (Factory or Customer),
become the current operating setpoints.
3.6 Alarms
As programmed into the system controller, an alarm condition
activates the summary alarm logic which illuminates the
alarm key and energizes an audible alarm. Some alarms are
programmed by the factory to automatically shut down the A/C
unit until the alarm condition is remedied and the alarm is cleared
by pressing the alarm key. Alarm conditions that shut down the
A/C unit are termed "Critical Alarms". Some of the alarms that
may be enabled by the factory are listed in Section 5.3.
3.6.1 Summary Alarm
A summary alarm will activate when the controller senses any
programmed alarm condition. This illuminates the alarm key
and a N.O./N.C. summary alarm contact is energized for remote
monitoring of alarm conditions.
