Issue
i28xx type of Infinet Controller has different range of WC (Water Column) than i28xx-V Infinet Controllers. What are the input voltage settings for i28xx and i28xx-V controllers' AirFlow sensor input?
Environment
Infinet controllers (i2865 & i2865-V, i2866 & i2866-V , i2885 & i2885-V)
Cause
Input settings for Velocity Pressure Sensor is different than the other regular analog input (voltage input) configuration.
Resolution
The i28xx type of Infinet Controller has 0~2" WC (Water Column) range, the input voltage should be set to 0~2V.
The i28xx-V type of Infinet Controller has 0~1" WC (Water Column) range, the input voltage should be set to 0~1V.
