Intermatic ST01A – Frequently Asked Questions

1) Does the Intermatic ST01A timer switch need a neutral wire in the box?
No neutral is required. The Intermatic ST01A 7-day heavy-duty timer runs without a neutral wire, so it drops into existing switch boxes on retrofit work where only the hot and switch leg are present.
2) Will one timer work on both 120V and 277V lighting circuits?
Yes. The ST01A is rated 120-277 VAC, 50/60 Hz, so the same part covers 120V residential circuits and 277V commercial lighting branch circuits. That is useful if you are standardizing one timer across a mixed-voltage building.
3) How much load can the Intermatic ST01A switch, and will it handle LED and fluorescent fixtures?
It is a 15A timer and the load list covers incandescent, fluorescent, CFL and LED fixtures. That is enough for typical parking lot, corridor, and exterior lighting branch circuits controlled from a single switch location.
4) Does this Intermatic timer adjust itself for sunset and for daylight saving time?
Both. The astronomical clock calculates dawn and dusk automatically so you are not resetting schedules every season, and daylight saving time adjustment is built in. For a property manager running exterior lights across several buildings, that removes the twice-a-year trip to each switch.
5) How many on/off events can I program on the ST01A in a week?
Up to 40 ON/OFF events over a 7-day schedule. That is enough to run different times for each weekday plus weekend, or to stage several on/off cycles a day for a ventilation fan.
6) Can I use the Intermatic ST01A to run an exhaust or ventilation fan, not just lights?
Yes. Listed applications are air movement and ventilation, indoor lighting control, and outdoor lighting control, so scheduling a ventilation fan is an intended use within the 15A rating.
7) What color is the ST01A, and will it match my existing devices?
This one is light almond. If your building is standardized on white or ivory device plates, the light almond face will read slightly off against them, so match the finish to the rest of the wall devices before you order a quantity.
8) Is there a vacation or security setting on this Intermatic timer?
Random mode varies the on/off schedule to give a lived-in look, which is what you want on vacant units or a residence left unoccupied. It works alongside the normal 7-day program rather than replacing it.
