  • Off: State is off. This is the value of the State Output when the System Enable is False.
  • Bypass Control: This is the active state when the System Enable transitions to True and the OAT temperature is below the Switchover Setpoint minus the Switchover Diff. Bypass Control is also active if the Tower Control Status is Low and the Condenser Water Temperature is less than or equal to the Condenser Water Setpoint and the OA Temperature has dropped below the Switchover Setpoint minus the Switchover Diff.
  • Tower Control: This is the active state when the System Enable transitions to True and the OAT temperature is above the Switchover Setpoint. Tower Control is also active if the Bypass Control Status is High and the Condenser Water Temperature is greater than the Condenser Water Setpoint.
  • Sensors Unreliable: This is the active state when either the OA Temperature or the Condenser Water Temperature are unreliable.
