This option adds a binary input to monitor the status of the heat wheel. If this option is selected, you need to consider a Loss of Status Strategy. This can be either Automatic Restart, which continually attempts to restart the heat wheel until the status indicates it is operating correctly, or Manual Restart, which stops the heat wheel until the alarm is reset. The manual restart option offers a choice of using a network input or Unit Reset Switch (BI) to reset the system.
