The Intermatic ST01 is a heavy-duty, 7-day programmable timer engineered for professional electricians and contractors who need reliable ON/OFF scheduling across a wide range of load types — from incandescent and LED lighting to fluorescent, CFL, motor, and resistive heater circuits. Rated for 120–277 VAC at up to 15A with no neutral wire required, it installs cleanly in both new construction and retrofit applications. The built-in astronomic clock automatically adjusts for sunrise and sunset year-round, while the 3-year battery backup ensures programming is never lost during a power outage. cULus listed and Title 20 compliant, the ST01 is a dependable choice for commercial and residential job sites throughout Ontario.
Key Features
| No Neutral Wire Required | Installs in single-gang boxes without a neutral connection — ideal for retrofit jobs in older construction where a neutral is not available at the switch location, reducing callbacks and simplifying rough-in. |
| Astronomic Clock with Countdown Mode | Automatically adjusts ON/OFF times based on local sunrise and sunset throughout the year, with Daylight Saving Time built in. Countdown mode (up to 24 hrs) adds flexibility for timed ventilation, signage, or temporary load control. |
| 3-Year Battery Backup | A replaceable CR2 lithium battery retains all programming for up to 3 years during power outages — no reprogramming required after a trip or breaker reset, keeping schedules intact on occupied job sites. |
