Description |
Default Value |
|---|---|---|---|
|
Damper Delay |
Allows the damper to start opening before the fan is energized. The damper delay defines the amount of time between the damper opening and the fan starting. |
30 Seconds |
|
|
Damper OpenClose |
Contains the control signal for the minimum OA damper. The enumeration set only has two values, Close and Open. |
Close Set Name: Close/Open |
|
|
Fan OnOff |
Contains the control signal for the minimum injection fan. The enumeration set only has two values, Off and On. |
Off Set Name: Off/On |
|
|
Low Limit Delay |
Defines the time the damper remains closed once the low limit process variable rises above the low limit setpoint. |
180 Seconds |
|
|
Low Limit Process Variable |
Contains the low limit temperature process variable. This temperature is usually the mixed air temperature or the preheat air temperature. |
7 °C, 45 °F |
|
|
Low Limit Setpoint |
Indicates the threshold for the low limit process function. When the low limit process variable is above this temperature, the damper and fan may be turned on to provide adequate levels of outdoor air. Below this setpoint, outdoor air levels may be limited by turning off the fan and damper until the low limit process variable remains above the setpoint for the Low Limit Delay. |
7 °C, 45 °F |
|
|
MOA-OUTSTATE (State) |
Indicates the current operational mode of the Output Controller. |
No Flow Set Name: AHU MinOA Fan State |
|
|
Mode |
Desired mode of operation. |
No Flow Set Name: AHU MinOA Fan Mode |
