When pairing remotes to a 1050 control board be sure to check the set programming for Radio channels.
Press the functions and scroll down to #4 "Radio Channels" and hit "okay" to enter. If radio channels show as "No program" or "Invalid" then remotes will not function even after being paired. Channel 1 corresponds to the top remote button and channel 2 corresponds to the bottom button. Changing both channel 1 and 2 to a "Step" command will give an open-stop-close functionality however these channels can be programmed for any desired functionality.
