ii. Proportional control

iii. Proportional plus integral control

iv. Proportional, integral, plus derivative control

Upon the resumption of normal power, each DDC controller shall analyze the status of all controlled equipment, compare it with normal occupancy scheduling and turn equipment on or off as necessary to resume normal operations.

Energy Management Routings:

DDC controllers shall have the ability to perform any or all the following energy management routines time-of-day scheduling:

i. Calendar-based scheduling

ii. Holiday scheduling

iii. Temporary schedule overrides

iv. Start-stop time optimization

v. Automatic daylight savings time switch-over

vi. Night setback control

vii. Temperature-compensated duty cycling

viii. Fan speed / CFM control / static pressure control

ix. Heating/cooling interlock

All programs shall be executed automatically without the need for operator intervention and shall be flexible enough to allow user customization. DDC controllers shall be able to execute custom, job-specific processes defined by the user, to automatically perform calculations and special control routines. It shall be possible to use any of the following in a custom process:

i. Any system measured point data or status

ii. Any calculated data

iii. Any results from other processes

iv. User-defined constants

v. Arithmetic functions (÷, -, *, /, square root, exp, etc.)

vi. Boolean logic operators (and/or, exclusive or, etc.)

vii. On-delay / off-delay / one-shot timers

Custom processes may be triggered based on any combination of time interval, time-of-day programming, and/or events (e.g., point alarms).

A single process shall be able to incorporate measured or calculated data from any and all other DDC controllers on the network. In addition, a single process shall be able to issue commands to points in any and all other DDC controllers on the network, Processes shall be able to generate operator messages and advisories to operator I/O devices.
