1. Expand the Central function. Modify the Group Number to 1 (It may already be set to 1).

1. With the Group Master selected, the VAV Automation Stations should display in the Group Members

tab.

NOTICE! All Automation Stations used in the Supply Air Temperature Reset calculations must

have an Assigned selection in this tab.

Note: All Central Functions can be grouped hierarchically, which is used for separating Group Member

and Master functions. Multiple Central Functions can be grouped like this to simplify floors, or to split

number of members. One group member can only have 255 objects for supply functions, so it may be

necessary to use two central functions depending on the number of objects.

2. Use Assign Selected or Remove Selected buttons to assign or remove the VAV Automation Stations

from the group.

Once the Terminal application is connected as shown, the Central Function should collect and read by the

data from the VAV box. This will allow the Central Function DXR to communicate with the AHU and

perform Supply Air Temperature Reset correctly.

While online in the Central Function DXR, EvlNumTSuCDmd (CHG DMD QTY) and EvlNumTSuHDmd (HTG

DMD QTY) will show the number of VAV boxes (from the group members) assigned to this DXR.
