Cooling Mode

  • Off : Set the Cooling Percent Cmd to 0%.

  • Max: Set the output for maximum cooling.

  • Limited Max : Set the output for maximum cooling with a limit.

  • Hold : Hold the output at it's current value.

  • Water Flush: Set the output to the Flush Position for either the cooling or heating based on the value of Flush Mode.

  • Control : Adjust the output to control the Process Variable (cooling only). If the Process Variable is reliable, the module controls the output in order to maintain the process variable at the Setpoint.

  • Failsoft : The state generation section can use this if the process variable is unreliable, the output is set to the Failsoft Cooling Value.

Heating Mode

  • Off : Set the Heating Percent Cmd to 0%.

  • Max: Set the output for maximum heating.

  • Limited Max: Set the output for maximum heating with a limit.

  • Water Flush: Set the output to the Flush Position for either the cooling or heating based on the value of Flush Mode.

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

  • Control: Adjust the output to control the Process Variable (heating only). If the Process Variable is reliable, the module controls the output in order to maintain the process variable at the Setpoint.

  • Failsoft: The state generation section can use this if the process variable is unreliable, the output is set to the Failsoft Heating Value.
