  • Off: Sets the Device OnOff output to off. The Percent Command is set to 0.0%.

  • On: Sets the Device OnOff output to on. The Percent Cmd is set to 100.0%.

  • Control: Sets the Device OnOff to on. When this state is first entered, a Rate Limit object begins to increase its output starting from zero. When the output of the rate limit reaches the minimum of the Percent Cmd input and the Percent Limit input, the minimum of those two inputs is passed to the Percent Command output. The Percent Command varies between Min Speed and 100.0% as the input Percent Cmd varies from 0.0 to 100.0%.

  • Hold: Holds the Device OnOff and Percent Command at the last output value.
