## Description

Wattstopper RT-200-W Astronomical Wall Time Switch, 24/7, 120/277V, White

Review: Work as billed - easy to install & use - Bought two of these to replace existing programmable switches that were causing problems. Original switches would reset with a brief power flicker (seconds) and programming was extremely complicated. These installed extremely easily. Programming almost did not even require the manual. They retain programming through brief power outages (I tested ~10 minutes)
Review: Love, love, love this timer! - Love this timer. Once it's set you'll never need to adjust it again. Purchased one thru our electrician and liked it so well, we bought another and installed it ourselves. Would highly recommend to anyone.
