    Introduction Introduction In the first chapter, the ECB-VAVS preloaded applications are introduced and an overview of this user guide is provided. Introduction to the ECB-VAVS Preloaded Applications Distech Controls’ ECB-VAVS controllers come preloaded with code containing standard VAV applica- tions. This code was created using EC- gfx Program, a Graphical Programming Interface (GPI) tool that enables visual assembly of building blocks and the design of custom programs that control Building Automation Systems.

    When the VVTMode (BV12) option is selected, ActFlowSP is converted into a percentage, which con- trols the damper without using a flow reading. The dual maximum option, DualMaximum (BV19), is available for the ECB-VAVS model. When in heating mode, ActFlowSP is controlled as follows (see Figure 1): The first 50 percent of the heating load adjusts the DischAirSP (AV12) between 55°F and MaxDischAirSP (AV56).
