The Intermatic ET2825C is a professional-grade 365/7-day astronomic time switch engineered for the demands of commercial and industrial electrical installations. Designed for professional electricians and contractors who need reliable, set-it-and-forget-it load control, the ET2825C delivers to-the-minute scheduling precision across virtually any application — from exterior lighting and signage to HVAC and irrigation systems. Its 100-hour power backup (no batteries required) ensures your schedules stay intact through outages, while 50 independent holiday blocks and 96 ON/OFF events give you the flexibility to handle even the most complex seasonal and operational requirements. The built-in astronomic function automatically adjusts ON/OFF times based on local sunrise and sunset, eliminating manual seasonal reprogramming and reducing energy waste on the job site.
