Pass & Seymour Programmable 24-Hour Astronomic Timer Switch, White

The Pass & Seymour Programmable 24-Hour Astronomic Timer automatically turns lighting and small motor loads on and off based on user programming, replacing standard single-pole and 3-way (1P/3W) wall switches. Finished in white with a gloss finish, this timer switch is an ideal solution for meeting California Title 24 (2019/2022 Part 6: Outdoor Control Device) and 2021 IECC residential energy code requirements for exterior lighting control. The astronomic feature automatically adjusts dusk-to-dawn times based on location, accounting for daylight savings time and seasonal shifts, while a built-in rechargeable battery backup preserves programming for up to 14 days in the event of a power loss.

Pass & Seymour RTPA24W – Frequently Asked Questions

1) Can the Pass & Seymour RTPA24W astronomic timer be used in a 3-way circuit with another switch?
Yes. The RTPA24W replaces standard single-pole and 3-way (1P/3W) wall switches, so it can go in place of either leg of a 3-way pair controlling the same lighting load.
2) Will this timer switch work with LED and CFL exterior fixtures, or only incandescent?
LED, CFL, and incandescent loads are all covered by the RTPA24W, and it will also run small motor loads, so it works for landscape and security lighting retrofits where fixtures have already been changed over to LED.
3) Does the Pass & Seymour RTPA24W satisfy California Title 24 outdoor lighting control requirements?
It is built for that purpose. The RTPA24W meets California Title 24 (2019/2022 Part 6: Outdoor Control Device) and 2021 IECC residential energy code requirements for exterior lighting control, which is why it gets specified on new residential construction in those jurisdictions.
4) Do I have to reprogram this timer when the seasons change or at daylight savings?
No. The astronomic function adjusts dusk-to-dawn times automatically based on location, accounting for daylight savings and seasonal shift. That is the practical difference between this and a plain 24-hour timer, which drifts out of step with sunset and needs manual correction several times a year.
5) What happens to the timer program if the power goes out?
A built-in rechargeable battery backup holds the programming for up to 14 days during a power loss, so a short outage or a breaker trip during other work does not mean reprogramming the schedule.
6) How many on/off events per day can be programmed on this astronomic timer?
The RTPA24W holds 7 ON and 7 OFF settings total for 24-hour scheduling every day of the week. It runs four modes: Manual, Automatic, Random, and Countdown, plus a Manual ON override that reverts to the programmed schedule within 6 hours.
7) Is the Pass & Seymour RTPA24W UL listed for commercial and institutional jobs?
Yes, it is UL Listed and cULus Listed, built to UL-CSA standards, and RoHS compliant, so it clears inspection on both US and Canadian work.
8) Is the Random mode on this timer useful for vacant units or vacation security?
That is what it is there for. Random mode varies switching times so a property reads as occupied, which is why property managers use it on vacant units and short-term rentals alongside the normal Automatic dusk-to-dawn schedule.
9) What color and material is the RTPA24W timer, and will it match other white devices on the wall?
White with a gloss finish, in steel and thermoplastic construction, so it sits in line with standard white gloss wiring devices on a multi-gang plate. The face carries a back-lit LCD for programming.
10) Is the Pass & Seymour RTPA24W sold individually or by the box?
The RTPA24W is packaged 10 each, which suits crews standardizing exterior switch locations across a tract or a multi-family building rather than a one-off replacement.
