                                The product functions well, but has a limited life of about three years. Needs better electronic switches.

                                                go to Honeywell website and cross check numbers, sometimes it's only a difference in how it mounts which may or may not work.

                                                According to the manufacturer, the numbers do not have any special significance in themselves. They simply make it easier to differentiate L8124C products.
