There are many items in your home that use a large amount of electricity, and while these items may be important, their power usage is costing you money. The Grasslin Digi 20E is a digital electric timing device that is professionally installed in your home or business. This device allows you to set up a programmable schedule for a certain circuit, such as a lighting system or heating and cooling system. This helps ensure the system is on when you want it and off when you want to conserve power.
