I bought the "Skytech 5320 Timer/Thermostat Fireplace Remote Control with Backlit Touch Screen" to replace the remote control system for a 20 year old Avalon Prairie gas fireplace. It works great!The original remote had a tiny screen that could be difficult to read. The screen on this remote is 3-1/2" diagonally (1-1/2" wide x 3-3/16" high) and is much easier see, even from a distance. The blue backlight stays on for only five seconds after touching the screen or a button, so that won't unnecessarily drain your batteries.If the remote control batteries die and you don't have replacements handy, the body of the receiver has a three-position switch you can use to operate your fireplace in the meantime.The installation took only a couple of minutes. It involved unplugging the old remote receiver, disconnecting the receiver's two wires, connecting the new remote receiver's two wires, and plugging in the receiver. Put batteries in the new remote. Done!Note: When connecting the new receiver, the two wires can be attached to either connector. You can't go wrong.
