The Braeburn Zoning Reference Guide 16 Part No. RG-0508-001
Additional Features for the 3-Zone Panels
The Braeburn 3-Zone Panel has additional features to control staging by monitoring the
temperature of the HVAC plenum. By using the Hi and Lo Temp cutout switches the installer
can con gure the panel to operate in the most economical mode.
When the 3-zone panel is con gured for a conventional system, the panel will upstage the
heating equipment if the plenum temperature is 25 degrees less than the cutout. If the panel
is con gured for heat pump, staging occurs at 10 degrees less than cutout. The same limits
are used for cooling staging.
The limit switches are located directly below the 3-zone panel LED. The display informs the
user of the panel condition and the plenum supply temperature.
