This wall control is NOT compatible with Security+ 2.0 models using yellow learn buttons.
The 378LM wall control is used with various LiftMaster® garage door openers as an additional wall control on 315MHz frequency openers.
Specifically designed for those who want an extra control panel in   the garage. This wall control can open   and close up to two garage doors, turn opener lights on/off, and can be   installed anywhere in the garage that is in the line of sight of the   garage door. It is not meant to be a substitute for a wired control   panel, however, as the garage door cannot be opened if the battery dies,   and remotes cannot be programmed from it. There is also no lock feature   to lock out outside remote control signals, or constant pressure to   override the garage door openers Protector System in case of   emergency.
The 378LM is NOT meant to be a substitute for a wired control panel, it is used in addition to your current wall panel.
