Parking lots, building façades, signs and HVAC equipment on multi-circuit schedules need one controller that follows sunset and holidays without a site visit. The Intermatic ET91215CR is a 12-circuit, 365-day astronomic time switch in an outdoor Type 3R steel enclosure, with Ethernet for remote control and monitoring. It auto-detects 120-277 VAC input and switches each circuit through 30 A rated contacts.
Why facility managers pick it
- Astronomic sunset-on and sunrise-off settings replace separate photocells.
- 365-day scheduling with holiday and exception programs plus automatic DST adjustment.
- Ethernet and USB let you copy, back up and update schedules and firmware in the field.
- 100-hour supercapacitor keeps time through outages with no battery to replace.
- Wire 12 SPDT or 6 DPDT circuits, expandable in 4-circuit modules to 16.

Pro tip from the counter
Don't size the job by multiplying 12 relays by 30 A. Intermatic caps total panel output at 350 A on the 4 to 16 circuit models, so on a big parking lot or building-wide lighting schedule, add up the actual connected loads and move heavy circuits onto lighting contactors driven by the clock.
Best for: parking lot and site lighting, building façade and sign lighting, HVAC and exhaust fan schedules, multi-tenant plazas, schools and municipal facilities
