Primary States (2 Pipe 2 Position Valve) - Johnson Controls - Metasys - LIT-12011147 - Software Application - Controller Configuration Tool - 16.0

Off: Turn everything off. The Percent Cmd, and Damper Percent Cmd is set to 0%.

Max: Open the valve and the damper. The Percent Cmd and Damper Percent Cmd is set to 100%.

Limited Max Heating: The valve is opened and the damper is opened to the Limited Max Heating Value. This state may be used for unoccupied heating. Percent Cmd is set equal to Limited Max Heating Value; therefore, this mode would be able to start the AHU.

Limited Max Cooling: The valve is opened and the damper is opened to the Limited Max Cooling Value. This state may be used for unoccupied cooling. Percent Cmd is set equal to Limited Max Cooling Value; therefore, this mode would be able to start the AHU.

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

Water Flush: The valve is opened and the damper is closed. The Percent Cmd is set to 0%, therefore this mode does not trigger the AHU to start.

Heating Control: If the Process Variable is reliable, open the valve and adjust the damper output to control the Process Variable at the Heating Setpoint. The Percent Cmd and Damper Percent Cmd are adjusted between 0% and 100%.

Cooling Control: If the Process Variable is reliable, open the valve and adjust the damper output to control the Process Variable at the Cooling Setpoint. The Percent Cmd and Damper Percent Cmd are adjusted between 0% and 100%.

Failsoft Heating: The valve is opened and the damper is opened to the Failsoft Heating Value. This state is used when the control temperature is unreliable. Percent Cmd remains unchanged so this mode does not trigger the AHU to either start or stop.

Failsoft Cooling: The valve is opened and the damper is opened to the Failsoft Cooling Value. This state is used when the control temperature is unreliable. Percent Cmd remains unchanged so this mode does not trigger the AHU to either start or stop.
