The ET2845C 365/7-Day Astronomic Electronic Control features independent 7-day programming for convenient flexibility when load switching differs daily. This electronic control provides dependable and uncomplicated performance, plus to-the-minute programming for accurate load control and reduced energy costs. Up to 48 ON and 48 OFF events can be preset to automatically repeat. Each event can be applied to any combination of circuits and days. Each circuit can be independently scheduled for Astronomic (Dusk/Dawn) ON/OFF events. In addition, the programming can be easily disabled by changing to the manual operating mode. An additional mode of operation allows for ON/OFF buttons to be used as a 2-hour override, in compliance with current regulations. Manual circuit control buttons operate circuits independently, based on the mode of operation. 50 Holiday Block Scheduling exception dates are available to prevent regularly scheduled events, or allow for a holiday schedule. Comes equipped with a supercapacitor to provide time and date retention for a minimum of 100 hours, and do not require batteries. Housed in a lockable enclosure for vandalism and tampering protection.

New Product Highlights


The Intermatic® line of occupancy sensors are engineered and tested for long-lasting performance. In-Wall and Ceiling Mount sensors in both PIR (infrared) and dual (PIR/ultrasonic) technologies can monitor virtually any area within a building, providing solutions for any retrofit or new construction project. They utilize zero-crossing technology to suppress inrush current impact, supplying reliable ON/OFF sensing no matter the lighting technology.


The Intermatic® ICUBE™ Adaptive Defrost Module cuts defrost cycles--and utility bills--for the food service industry. Designed by Grässlin by Intermatic for commercial walk-in coolers and freezers, the smart-sensing technology behind the ICUBE™ continuously monitors evaporator coil temperatures and only allows defrosting when necessary at the next programmed timer interval.

Surge Protective Device Group Shot

The Intermatic® Surge Protective Device with Consumable Modules covers 100% of a home’s big investment equipment, from appliances and computers, to HVAC equipment and TVs. The Surge Protective Device uses replaceable Consumable Modules that allows homeowners to easily and safely replace a module when the built-in LED light indicates it has been compromised.
