Zone Alarm Offsets

Hi Zone......: XXºF

Lo Zone......: XXºF

The VAV/Zone Controller can be setup to generate an alarm anytime the
box goes into the Occupied Mode and the Zone Temperature exceeds
the user-defi ned alarm limits for a user-defi ned period of time. A High
Temperature Alarm Setpoint
is created by adding the Hi Zone Alarm
offset to the current Cooling Setpoint. The Low Temperature Alarm
Setpoint
is created by adding the Lo Zone Alarm offset to the cur-
rent Heating Setpoint. If the zone temperature exceeds either of these
limits for a period defi ned by the Alarm Delay setpoint, the controller
can generate an alarm callout if all the optional hardware components
required for this to occur are installed.
