Cooling Mode

The following cooling modes are only active when the SummerWinter input is set to Summer.

• Off: Set the Percent Cmd to 0%. The state is Off.

• Max: Set the output for maximum cooling. The Heating Percent Cmd is set to 0% and the Cooling and Percent Cmds are set to 100% if in Summer mode. The state is Max Cooling.

• Limited Max: Set the output for maximum cooling with a limit. Similar to the Max Cooling command except the maximum value is specified by the user through the Limited Max Value input. The state is Limited Max Cooling.

• Water Flush: Set the output to the Flush Position value. The state is Water Flush Cooling.

• Hold: Hold the Percent Cmd output at its current value. The state is Hold. If the Output Overridden is true, then the Output Position input is passed to the Cooling Percent Cmd.

• Control: Adjust the output to control the Process Variable (cooling only). If in Summer mode and the Process Variable is reliable, the module controls the output to maintain the process variable at the Cooling Setpoint. The state is Control Cooling.

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

Heating Mode

The following heating modes are only active when the SummerWinter input is set to Winter.

• Off: Set the Percent Cmd to 0%. The state is Off.

• Max: Set the output for maximum heating. The Cooling Percent Cmd is set to 0% and the Heating and Percent Cmds are set to 100% if in Winter mode. The state is Max Heating.

• Limited Max: Set the output for maximum heating with a limit. Similar to the Max Heating command except the maximum value is specified by the user through the Limited Max Value input. The state is Limited Max Heating.

• Water Flush: Set the output to the Flush Position value. The state is Water Flush Heating.

• Hold: Hold the Percent Cmd output at the current value. The state is Hold. If the Output Overridden is true, then the Output Position input is passed to the Cooling Percent Cmd.

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

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