The following table describes the attributes used by the Fan Three Speed modules.
|
Name |
Description |
Default Value |
|---|---|---|
|
Cooling Percent Cmd |
Percent cooling, typically connected from the cooling output module. In Auto Low and Auto Medium Modes, the value is used to determine fan speed based on threshold values. |
|
|
Fan OnOff |
Indicates that the fan is off or on. |
Set Name: Off/On |
|
Fan OnOff 1 |
Contains the output for fan speed 1. |
Set Name: Off/On |
|
Fan OnOff 2 |
Contains the output for fan speed 2. |
Set Name: Off/On |
|
Fan OnOff 3 |
Contains the output for fan speed 3. |
Set Name: Off/On |
|
Fan Speed Status |
Contains the feedback to zone sensor and/or other display to indicate the current control state (auto/off) and speed (off/low/medium/high) of the fan. |
Set Name: Three Speed Status |
|
FAN-OUTSTATE (State) |
Current operational state of the output controller. |
Set Name: Off/On/Max |
|
Heating Percent Cmd |
Contains the percent cooling, typically connected from the heating output module. In Auto Low and Auto Medium Modes, this value is used to determine fan speed based on threshold values. |
|
|
Mode |
Mode requested by State Selection. |
Off Set Name: Off/On/Max |
|
Speed 2 Off Threshold |
Used when Mode = Auto-Low to determine whether to decrease fan speed to Low (done if the larger of the cooling and heating percentages is less than or equal to this value). |
30.0% |
|
Speed 2 On Threshold |
Used when Mode = Auto-Low to determine whether to increase fan speed to Medium (done if the larger of the cooling and heating percentages is greater than this value). |
35.0% |
|
Speed 3 Off Threshold |
Used when Mode = Auto-Low or Auto-Medium to determine whether to decrease fan speed to Medium (done if the larger of the cooling and heating percentages is less than or equal to this value). |
65.0% |
|
Speed 3 On Threshold |
Used when Mode = Auto-Low or Auto-Medium to determine whether to increase fan speed to High (done if the larger of the cooling and heating percentages is greater than this value). |
70.0% |
|
Stage Down Delay |
Specifies the time that all outputs are turned off when the requested speed is decreased one stage before the next lower stage is turned on. This time allows the motor to slow down before re-engaging the motor at the lower speed. If the speed is decreased two stages (from High to Low), the outputs are held off for twice the time. |
