Pass & Seymour TS400I – Frequently Asked Questions

1) How much lighting load can the TS400 timer switch handle?
The TS400 is rated 0-800/1200W of lighting load. Total up the fixture wattage on the circuit before you commit; a bank of high-wattage HID or older fluorescent ballasts can exceed that, in which case you switch a contactor with the timer rather than the load directly.
2) Is the TS400 a countdown timer or a 7-day programmable timer?
It's a countdown timer. The TS400 turns the connected lighting off after a preset interval, adjusted up or down with the time scroll feature and shown on the LCD. If you need lights to come on and off at set times of day on a weekly schedule, this is the wrong type of device, you want an astronomic or 7-day programmable time switch instead.
3) Does the TS400 timer switch use screw terminals or push-in wire leads?
Terminal-style wiring. The TS400 uses screw terminal connections rather than pigtail leads, which keeps the box fill down and makes it faster to land conductors in a crowded single-gang box on a retrofit.
4) What colors does the Pass & Seymour TS400 digital timer switch come in?
Two: white (TS400W, ordered as TS-400-W) and ivory (TS400I). Both carry a matte finish, so they sit alongside standard matte-finish device plates without a gloss mismatch. Pick the one matching the other devices on the wall.
5) Can occupants tell before the lights shut off with the TS400?
Yes, there are optional audible or visual alerts that warn occupants ahead of shutoff. That matters in restrooms, stairwells and storage rooms where someone may still be in the space; they get a cue to press the button and add time rather than being dropped into the dark.
6) Can you read the TS400 timer display in a dark room?
The countdown is shown on a bright electroluminescent LCD, so it stays readable in low light. Useful for the applications these timers usually land in, closets, mechanical rooms and unlit corridors.
7) Is the TS400 suitable for residential use or is it a commercial-only device?
Both. Pass & Seymour positions the TS400 Wattstopper digital timer for commercial and residential lighting control, including new construction and renovation wiring. Property managers use it for the same reason contractors do: it enforces automatic shutoff in spaces where switches get left on.
