Dampers Force Mode Screen
If the unit ID you entered is for a SA Controller that has VAV/Zone
controllers connected to its communication loop, the Damper Force
Mode will act as a “Global” Damper Force Mode. That is, all VAV/Zone
controllers on that SA Controller’s communication loop will be forced
to the same Damper Force Mode setting. If the unit ID you entered is
for a VAV/Zone controller, the Damper Force Mode setting will only
apply to that VAV/Zone controller.
Damper Force ID 102
Enter Force Mode: 0
0=Auto 1=Open 2=Clsd
3=Max 4=Min 5=Fixed
Set the appropriate Damper Force Mode by entering numbers 0 through
5. The Force Modes for each of these settings is outlined below.
0 = Auto This is the default setpoint. With this setting,
the damper will operate normally and modulate
according to the controller setpoints.
1= Open This setting will force the damper to its fully-
open position.
2= Clsd This setting will force the damper to its fully-
closed position.
3= Max This setting will force the damper to the damper’s
maximum airfl ow position set under VAV/Zone
Controller Setpoint Screen #5 (see page 48).
4= Min This setting will force the damper to the current
mode’s minimum position setpoint. These modes
are Vent Mode, Heat Mode, and Cool Mode. They
may each have a different minimum depending on
how you confi gured the setpoints. See VAV/Zone
Controller Setpoint Screen #5 on page 48.
5= Fixed This setting will force the damper to a fi xed
position based on the fi xed position setpoint.
See VAV/Zone Controller Setpoint Screen #8 on
page 49 for available setpoint information.
Caution: The Damper Force Modes should only be used by quali-
fi ed service personnel. Serious damage to the ductwork
could result if the dampers are all forced closed and the
HVAC unit fan is operating.
