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.
