Scope and Purpose

This document provides an overview of the Central Operating Mode function and de-

scribes how to configure Central Functions and DXRs to coordinate properly. This cen-

tral function can be very useful for projects that have schedules that include warm-up

and/or cool-down. This document should give a brief overview of Central Operating

Mode in order to determine if it would help for your specific project.

The Central Operating Mode function requires careful consideration and planning

before any configuring and implementation. Like all central functions, it relies heavily

on group master/member communication and grouped hierarchies. This document

provides a clear configuration path, but it is important to determine first if it is

appropriate for a project.

This document describes how to

• Set up initial DXR application configuration parameters.

• Set up a Central Function DXR in conjunction with the room controller

• Configure the use of signals to coordinate Central Operating Mode

DXR Templates and Central Functions

Templates from Hvac12 (VAV) and Hvac13 (FPB) DXR application types come with

datapoints that can be used in conjunction with AHU primary plant controllers to control

and monitor the zone dampers for reset. In addition, a Central Function DXR can be

used to easily bridge data between the zones and the AHU. The DXR template

applications and Central Function DXR together allow for efficient collection of room

data for use in Central Operating Modes.

Title 24 Fault Detection for VAV and FPB Templates

For compliance with Title 24, an FDD configured template must be used.

FDD templates are located on StdApps under Apogee > Desigo_ABT >
