Determine which Systems and Codes are required:
* _IBC/IECC 2021 or later:_ all fixtures 0-10V dimmable.

* `System` = "LV - Lighting Control System"

## Wall Switches

> For switch combinations not in `COMMON ASSEMBLIES`,
> create [[heating-designations]] based on the most similar.

## Analog Controls

24V sensors. Typical of BOH spaces too large for wall sensors.

1. `COMMON ASSEMBLIES`/`SWITCHES`/`CEILING OCC SENSOR ...`
    **Count:** as shown.

2. `COMMON ASSEMBLIES`/`SWITCHES`/`POWER PACK FOR OCC SENSOR ...`
    **Count:** each circuit controlled by analog sensors. Minimum 1 per sensor.

## Digital Controls

Applicable to all digital control systems
(i.e. "Standalone" and "Centralized", wired and wireless)

### General

Takeoff normal power to the controlled load
* Add LV cable to fixture branch
* Use switched assemblies (\#12/3) for controlled receptacles

#### Digital Sensors

1. `COMMON ASSEMBLIES`/`SWITCHES`/`LOW VOLTAGE SWITCHES & OCC SENSORS - ROUGH IN`/...
    * `... LV SW - WALL ROUGH IN ...`
    * `... SENSOR LOW VOLTAGE - ROUGH IN ...`

### "Standalone" Systems

Room controllers distributed throughout controlled areas.

> [!important] "Room controllers"
> As I have always understood it, and other manufacturers tend to agree,
> a room controller _necessarily_ controls multiple zones
> (otherwise "zone controller" would be better),
> however PDI terminology is based on Wattstopper's.

`COMMON ASSEMBLIES`/`SWITCHES`/`LOW VOLTAGE SWITCHES & OCC SENSORS - ROUGH IN`/...

1. .../`DLM LTG RM CONTROLLER - ...`
    **Count:** each lighting control zone.

2. .../`REC PLUG CONTROLLER - ...`
    **Count:** each receptacle control zone.

3. `HEATING`/`Network Bridge - Blank 4SQ`
    **Count:** each controller.

    Coordinate with PDS to determine if necessary.

4. `COMMON ASSEMBLIES`/`PDI BRANCH CKT HOME RUNS`/... (_without_ dimming cable)
    **Count:** each _circuit_.

### "Centralized" Systems

Zones switched and dimmed from central lighting control panel (LCP).

1. `COMMON ASSEMBLIES`/`DISTRIBUTION`/`LIGHTING CONTROL PANEL INSTALLATION`/...

2. `COMMON ASSEMBLIES`/`PDI BRANCH CKT HOME RUNS`/... (_with_ dimming cable)
    **Count:** each _lighting control zone_.

### Somewhere In Between

The dichotomy of [[#"Standalone" Systems]] vs. [[#"Centralized" Systems]]
assumes zones will be controlled either
(1) right next to the fixture or (2) in the nearest electrical room.

I think just as common is 3--5 circuit controllers above the ceiling.

1. `HEATING`/`Lighting Control Room Controller - n Circuit`
    **Count:** each controller.

2. `COMMON ASSEMBLIES`/`PDI BRANCH CKT HOME RUNS`/... (_without_ dimming cable)
    **Length:** route to room.
    **Count:** each circuit.
