The Night Min is the position the damper will move to when the

system is in Override Mode and this particular damper is not part

of the override group. This Night Min position only affects non-fan

powered boxes. The Fan On Min is the minimum damper or airﬂ ow

setting used to activate the parallel fan if installed. Pressure Inde-

pendent = CFM. Pressure Dependent = %.

Many times while troubleshooting a system, it is useful to have the

zone damper set to a speciﬁ c damper position or airﬂ ow setting. This

setpoint can be used to determine where the damper/airﬂ ow will

remain when the VAV/Zone Controller receives a Force to Fixed

Position command.

Setpoint Screen #11 - SAT HVAC Mode

Deadband

XX Box Spts IDXXXX

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 ex-

ceeds 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 generate 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
