SAT HVAC Mode

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.

Setpoint Screen #12 - Zone Alarm Offsets

XX Box Spts IDXXXX

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.

Description Minimum Default Maximum

Hi Zone Alarm +1ºF +30ºF +50ºF

Lo Zone Alarm -1ºF -30ºF -50ºF

Occupied Mode that the temperature must be outside the alarm limits

before an alarm is generated.
