The Supply VAV air damper device mode (VavSuDevMod) is a multistate value that supports the following states:
- Off
- Control mode (modulation)
- Maximum air volume flow
- Minimum air volume flow
- Smoke air volume flow setpoint
(Dual duct VAV boxes only) For a dual duct VAV box, see table for Duct 1 and Duct 2 supply damper behavior:
Device mode | Duct 1 | Duct 2 |
---|---|---|
1:Off | Setpoint is zero | Setpoint is zero |
2:Control mode | Follows demand | Follows demand |
3:Max.air vol.flow | Select from h/c maximum according to VavSuChovrCnd1: | Select from h/c maximum according to VavSuChovrCnd2: |
4:Min.air vol.flow | Select from h/c minimum according to VavSuChovrCnd1: | Select from h/c minimum according to VavSuChovrCnd2: |
5:Smoke ctrl.air flow setp | Setpoint is smoke value | Setpoint is smoke value |
