Title: All 3 with unusable LCD screens at night
Review: We have 3 of these Lux systems in our sprawling house. All 3 have in a few short years had the LCD screens become unusable at night with the incorporated light. The programming part works well enough, The LCD is ok in a well-lit area, but we need to use a flashlight every time we want to adjust them. Not surprisingly, we adjust them less often. It is very frustrating and seriously compromises and otherwise good product.
