1. What configuration property of the <strong>Tracer</strong> MP580/581 controller must<br />

be set for the unit to enter occupied standby mode?<br />

2. Occupied bypass mode, previously known as timed override, is mentioned<br />

in the sequence of operation. How is occupied bypass mode<br />

accounted for in the configuration and programming?<br />

3. Data communicated from other devices is not always reliable. For<br />

instance, a temperature sensed by another Comm5 device may be<br />

invalid. This may be caused by a communications failure. How would<br />
