Additional Information and Considerations
Tracer SC Network Configuration
You should be aware of these important facts about Communicating Thermostat capabilities in the Tracer SC network.
No automatic installation
The Trane Communicating Thermostats do not automatically install on the Tracer SC. Custom templates are available and you can select one of these templates (“Template: TStat_RTU_Trane,”
p.40, “Template: TStat_FanCoil_Trane,” p. 36, or “Template: TStat_HeatPump_Trane,” p. 39) to get the unit ready to install. Refer to the Tracer™ SC System Controller Installation and Setup Manual
No priority array
Binary, Analog, and Multistate Values do not use a priority array. In order to reliably control these points, they must be controlled by only one source (for example, Area control). If they are being controlled from multiple sources, the most recent source to control the point will be in control.
Night Purge disabled
A Trane Communicating Thermostat as a member of Area should have Night Purge disabled. Using Night Purge could result in the Heat Cool Mode Request being controlled incorrectly on a transition from Night Purge to another state. You can disable Night Purge for the entire area on the functions page of Area in the Economizer Control section (Figure 5).
Figure 5. The Economizer Control section of the Area Functions page
Night purge can also be disabled from the members page by checking the box next to certain members and going to actions > edit configuration (Figure 6).
