Deadband.: XXºF

If the supply air temperature is above the space temperature by this
amount, the VAV/Zone Controller enters the Supply Air Heating Mode.
It will remain in the Supply Air Heating Mode until the supply air drops
to 2ºF above the space temperature. At that point the unit enters the
Supply Air Vent Mode and remains there until the supply air drops this
deadband below the space temperature. At that point the VAV/Zone
Controller enters the Supply Air Cooling Mode and will remain there
until the supply air temperature rises to 2ºF below the space temperature.

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 current
Heating Setpoint. If the zone temperature exceeds either of these limits
for a period defi ned by the Alarm Delay setpoint, the controller can gen-
erate an alarm callout if all the optional hardware components required
for this to occur are installed.
