Brand new upgrade alternative remote for the TAC490. This item is the direct replacement for all the old TAC490 remotes. The old TAC490 remotes are not longer in production. This remote does not require any programming to be used. Simply insert 2 x AAA batteries and it will control your AC. It also has all the functions of your old remote including the multiple timers. Please note the display is in Celsius but it works perfectly with Farhrenheit AC's.
