LM2-0-120

LM2-0-120

The LM2-0-120 operates on ambient light level sensing. LightMaster is an affordable alternative to expensive or unreliable lighting controls. It is a cost effective solution for providing additional light level control beyond the typical timer or photo control. It can be added to an existing timer. LightMaster offers true dusk-to-dawn operation and can achieve additional energy savings by adjusting light levels throughout the day or night. Additionally, it offers an affordable solution for daylight harvesting. The LightMaster features a delay setting to avoid nuisance ON/OFF switching of lighting during intermittent environmental changes, such as clouds, lightning, or headlights. The LightMaster is essential where activities are impacted by changing and inadequate light levels throughout the day. It will turn lighting ON during inclement weather and OFF when normal light levels resume. The LightMaster is more reliable than photo controls and can save maintenance costs over time.

New Product Highlights

IOS-DDR-W

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.

ICUBE

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.
