Title 24 · California Energy Code
Automatic scheduling, time-switch controls and holiday shutoff rules
If you operate lighting at a home or business, the California Energy Code requires automatic scheduling or time‑switches that can dim and turn lights OFF during scheduled unoccupied periods (outdoor controls must reduce power **50–90%** and allow at least **two nighttime scenes**), any manual override that forces ON is strictly time‑limited (commonly **2 hours**), and time‑switches must include an automatic **holiday shut‑off** that turns loads OFF for **at least 24 hours** then resumes normal scheduling; exceptions apply for certain occupancies and where occupant sensors are used .

What the code requires — 2-4 sentences
The California Energy Code requires that outdoor lighting be put on automatic scheduling controls able to dim (reduce) and turn OFF lighting during scheduled unoccupied periods (§ 130.2(c)2) and that time‑switch controls used to meet automatic shut‑OFF requirements include an automatic holiday “shut‑OFF” that turns loads OFF for at least 24 hours before resuming the normal schedule (§ 130.1(c)4). For residential outdoor lighting, time‑switch (or equivalent) controls are permitted but any manual ON override that forces the control ON must automatically restore the schedule within a limited time (see § 120.6(b)3A) .
The single most important rule: automatic scheduling/time‑switch controls must both be able to (1) reduce lighting power substantially during scheduled unoccupied times and (2) provide a holiday shut‑off that turns loads off for at least 24 hours before normal scheduling resumes (see § 130.2(c)2 and § 130.1(c)4) .
Requirements in detail
Definitions / first‑mention keywords (bolded): automatic scheduling controls, time‑switch control, holiday shut‑off, override.
Core functional requirements (by application)
| Decision dimension | Required value / behavior | Code Reference |
|---|---|---|
| Use case — outdoor site lighting | Automatic scheduling controls must be installed for all outdoor lighting and may be combined with motion sensors or other controls | § 130.2(c)2 |
| Outdoor scheduled unoccupied reduction | Must be capable of reducing outdoor lighting power by 50% to 90%, and must also be separately capable of turning lighting OFF during scheduled unoccupied periods | § 130.2(c)2(B) |
| Minimum number of scheduled nighttime scenes | Automatic scheduling controls shall allow scheduling of at least two nighttime periods with independent lighting levels (i.e., multistep/nighttime scenes) | § 130.2(c)2(C) |
| Outdoor override limit | If an override turns lighting ON during a scheduled dim or OFF state, the override may operate no more than 2 hours before the schedule resumes | § 130.2(c)2(C) |
| Holiday shut‑off (general/time‑switch) | Time‑switch controls installed to meet automatic shut‑OFF must incorporate an automatic holiday shut‑off that turns OFF all connected loads for at least 24 hours, then resumes normal schedule | § 130.1(c)4 and § 110.9(b)1A |
| Indoor manual override for time‑switch controls | When an automatic time‑switch control is used for indoor lighting shut‑OFF, it must include a manual override that allows lights to remain ON no more than 2 hours when initiated (exceptions apply) | § 130.1(c)3 |
| Residential outdoor controls — allowed control types | Residential outdoor lighting permanently mounted to a dwelling must be controlled by photocell + motion sensor, photocell + automatic time switch, or astronomical time clock (any of these is acceptable) | § 120.6(b)3A |
| Residential override behavior | Overrides that force ON are not allowed unless the override automatically returns to normal operation within a limited time (the Code specifies the automatic return requirement — see residential section) | § 120.6(b)3A |
| Time‑switch device backup | Time‑switch devices must have program backup to retain schedule at least 7 days and keep date/time at least 72 hours if power loss occurs (applies to time‑switch controls per § 110.9) | § 110.9(b)1 |
Notes on the table
- The 50–90% reduction and 2+ nighttime periods are explicitly required for outdoor scheduling controls; these are the key decision values when selecting a control product or specifying a control strategy for a site lighting design .
- The 24‑hour holiday shut‑off is written as a feature of time‑switch controls used to meet shut‑OFF requirements and appears several places in the Code; expect it for both indoor time‑switch compliance and some outdoor arrangements (exceptions listed below) .
How the pieces fit together (functional stack)
- For nonresidential outdoor lighting, implement a photo control or astronomical time‑switch to shut OFF in daylight, and add automatic scheduling controls that provide the 50–90% dim and OFF capability plus multiple nighttime scenes and override limits per § 130.2(c) .
- For indoor spaces that use a time‑switch to meet automatic shut‑OFF, the time‑switch must include a manual override limited to 2 hours and an automatic holiday shut‑off (24 hours) per § 130.1(c) .
- For residential outdoor lighting, follow § 120.6(b)3A: use one of the approved control pairings and ensure any override returns automatically to normal operation within the Code‑required limit .
Exceptions & special cases
- Holiday shut‑off exceptions: Retail stores, malls, restaurants, grocery stores, churches and theaters are not required to have the automatic holiday shut‑off feature when a time‑switch is used for automatic shut‑OFF (see § 130.1(c)4 exceptions) .
- Areas where occupant sensing controls are installed: the holiday shut‑off requirement may not apply where occupant sensing controls are in place (exceptions in the same subsection) .
- Continuous‑use areas: the scheduled shut‑OFF/scheduling controls may be exempt where lighting must be continuously lit 24/7 by statute or life‑safety requirement (see the exceptions in outdoor and indoor control sections) .
- Countdown timer switches: permitted only in very limited applications (e.g., closets <70 ft² or server aisles) and with very short maximum settings — do not use countdown timers as a general substitute for time‑switch controls to meet these requirements .
Common mistakes
- Specifying a controller that cannot both dim to the required percent and turn OFF separately. The Code requires both functions (reduce 50–90% and separately OFF) for outdoor scheduled unoccupied periods — choose a product that explicitly supports both per channel/zone (§ 130.2(c)2) .
- Allowing an indefinite override. For indoor time‑switches and outdoor scheduling overrides, the Code caps override ON durations (commonly 2 hours) and mandates automatic resume of schedule; planning teams sometimes forget this and accept longer overrides by habit, which is noncompliant (§ 130.1(c)3, § 130.2(c)2(C)) .
- Forgetting the holiday shut‑off feature in time‑switch products. Many installers assume “astronomical clock” or “programmable timer” is sufficient — verify the product has an explicit holiday shut‑off feature that turns off for at least 24 hours then resumes schedule (§ 130.1(c)4, § 110.9(b)1A) .
- Using countdown timers or plug strips to meet controlled receptacle requirements — countdown timers are only allowed in narrow circumstances, and plug‑in strips are explicitly disallowed to satisfy receptacle control rules .
- Selecting outdoor motion sensors that attempt to control more than 1,500 W per sensor/zone (limit appears in related outdoor control sections) — keep zone sizing in spec to meet the Code limits for motion sensor zones .
Worked example — parking lot + office lobby
Scenario:
- A medium retail site has a parking lot (nonresidential) and an adjacent office lobby (interior common area). The owner wants energy‑saving schedules plus occasional extended hours for special events.
What to specify (numbers):
Parking lot: install automatic scheduling controls that:
- Reduce lighting power by 70% during the late‑night scheduled unoccupied period and are separately capable of turning the luminaires OFF during scheduled gaps; the schedule includes two nighttime periods (late‑evening dim and overnight low/standby) per § 130.2(c)2 .
- Provide an override that allows momentary ON for security checks but automatically limits that override to 2 hours (and preferably to a shorter default) before the schedule resumes, per § 130.2(c)2(C) .
- Provide a holiday shut‑off function if an automatic time‑switch is used in the control stack (per § 110.9/130.1 requirements), so the system will turn all controlled lighting OFF for at least 24 hours on declared holiday events and then resume normal scheduling .
Office lobby: use an automatic time‑switch to meet automatic shut‑OFF where occupant sensing is not appropriate.
- Ensure the time‑switch has a manual override limited to no more than 2 hours (except if the lobby qualifies for an exception), and include the 24‑hour holiday shut‑off function on the time‑switch per § 130.1(c) requirements .
- Verify the time‑switch stores program backup (retain schedule 7 days, date/time 72 hours) per § 110.9(b)1 to avoid schedule loss during power interruptions .
Why these numbers: the 50–90% reduction range and 2+ nighttime periods are Code requirements for outdoor automatic scheduling; the 2‑hour override and 24‑hour holiday shut‑off are Code requirements for time‑switch/manual override features cited above .
Related provisions
- § 110.9(b)1 — Time‑switch device backup and timekeeping accuracy requirements (program/date retention) .
- § 130.1(c)3 — Manual override limits for automatic time‑switch controls (indoor) .
- § 130.3(a) — Sign lighting automatic time‑switch requirements for indoor/outdoor signs .
- § 130.4 — Acceptance testing and Certificate of Acceptance requirements for lighting and receptacle controls (testing & commissioning) .
- § 160.5(c)2 / § 160.5(b)4 — Parallel outdoor and multifamily control requirements that use similar scheduling and motion sensor rules (useful cross‑references when applying to multifamily or replacement projects) .
If you need, I can:
- Provide a short spec sheet you can give to an electrical contractor listing specific product features to verify (e.g., dimming percent range, holiday shut‑off feature, backup retention, override timing limits).
- Review a proposed control product data sheet and flag any gaps vs. the Code text cited above.

Frequently asked questions
What exactly is “holiday shut‑off” and how long must it turn lights off?
A holiday shut‑off is an automatic feature in a time‑switch that turns off all connected loads for at least 24 hours and then resumes the normally scheduled operation; this is required where an automatic time‑switch is used to satisfy shut‑off requirements (see § 130.1(c)4) .
Are retail stores required to have the 24‑hour holiday shut‑off?
No. The Code lists retail stores, malls, restaurants, grocery stores, churches, and theaters as exceptions to the automatic holiday shut‑off requirement under § 130.1(c)4 .
Can I use a countdown timer switch to meet these requirements?
Not generally. Countdown timer switches are allowed only in very limited locations (for example, closets <70 ft² or server aisles) with short maximum settings; they are not an acceptable substitute for time‑switch controls in most areas required to have automatic time‑switches (§ 130.1(c)2, § 160.5(b)4Cii) .
What limits apply to manual overrides?
Time‑switch controls used to meet automatic shut‑OFF must include an override that allows the controlled lighting or receptacle to remain ON no more than 2 hours when initiated (exceptions apply for certain spaces) — see § 130.1(c)3 and related subsections .
For residential outdoor lighting, what control pairings are allowed?
Residential outdoor luminaires permanently mounted to the building must be controlled by one of these: (a) a photocell + motion sensor, (b) a photocell + automatic time switch control, or (c) an astronomical time clock. Any override that forces ON must automatically return to normal operation within the Code‑required limit (§ 120.6(b)3A) .
