6.12Alarm Enable

Each alarm can be disabled or enabled. Use the Up and Down arrows to select a particular alarm, press Enter to select either Enable or Disable. Press Enter again to store the change. When the alarm is disabled it will NOT report to either the wall box beeper or to the common alarm relay.

NOTE

The high-water alarm will automatically shut the unit Off, even if the alarm is disabled. Similarly, optional factory-installed smoke sensor is wired to shut off the evaporator unit, regardless of the enable/disable status.

6.13Alarm Time Delay

Each individual alarm can be programmed with a time delay, causing the unit to delay a specified amount of time (0-255 seconds) before recognizing the alarm. See Table 19 for the default times. The alarm condition must be present for the full amount of the time before the alarm will sound. If the alarm condition is diverted prematurely, the alarm will not be recognized and the time delay will automatically reset.

NOTE

For software alarms such as “loss of power” and “short cycle,” the time delay should be left at the factory default of 0.

6.14Common Alarm Enable

Each individual alarm can be selected to activate or deactivate the common alarm relay. If the energize common alarm function is set to Yes, the relay is energized immediately as the alarm is annunciated and de-energized when the alarm condition has been recognized. If the alarm is completely Disabled, the alarm has no effect on the common alarm relay. Use the Up and Down arrows to scroll to a particular alarm, press the Enter button to select it, then press the Enter button again to select Yes or No.
