  • Off: Sets the Common Percent Cmd to 0%.

  • Max: Sets the output for maximum and sets the Percent Cmd to 100%.

  • Control: Adjusts the output to control the process variable. If the process variable is reliable, the module controls the output to maintain the process variable at the setpoint.

  • Hold: Holds the outputs at their current position. If the Output Overridden is true, then the Output Position input is passed to the Cooling Percent Cmd.
