The device is enabled when the State output is True and disabled when the State output is False. The following table shows the command hierarchy used to determine whether the State should be True or False. The Hardware Mode is determined by the OA Temperature being compared with the OA Temperature Enable Setpoint and by whether it is configured for heating or cooling. For example, when configured for heating, and the OA Temperature is below the setpoint, the Hardware Mode is True. If the OA Temperature is not reliable, then the Hardware Reliability is False. Network Mode and reliability is determined by the IsAvailable input.
