15 <br />What We Can Do <br />Key Findings <br />Trane can utilize features and capabilities of the Tracer SC system to introduce additional control modes such <br />as, Night Purge, Conditional Duct Static Optimization, Ventilation Prioritization. These modes will apply <br />newly installed ventilation sequences in the Tracer SC system. The new ventilation sequences will prioritize <br />the introduction of outdoor air into the building to dilute the buildup of indoor air contaminates. <br />Boiler sequencing strategies can be implemented to ensure adequate heat is available to allow units to <br />dehumidify. With the update of Tracer SC to Tracer SC+/Synchrony, advanced programming strategies <br />become available (Trim/Respond) to monitor VAV demand and reset the hot water temperature versus simply <br />doing a linear reset based on Outdoor temperature. This will allow the system to provide the adequate heat <br />needed during dehumidification as well as save energy by lowering the hot water setpoint when the heat is <br />not required regardless of outdoor temperature. <br />n <br />f y� <br />
