Here's a hint for owners of Stanley dipswitch programmed openers using the 1050 remote:

For some reason, the dipswitches in the Stanley 1050 remote are marked "Open" on one side, and "Closed" on the other side. A logical person might think that 'Open' means the circuit is completed when the switch is moved to that side, right? Not so fast! The terms 'Open' and 'Closed' are electronic terms, so 'Open' means the circuit is open, (imagine a knife switch being moved up, away from the contacts),  as in the switch is NOT making a path for electricity. "Closed" means the circuit (imagine a knife switch being moved down, touching the contacts on the other side of the circuit so it makes a path for electricity) is actually ON. In short, OPEN = OFF or "-" as some other dipswitches are marked. CLOSED = ON or "+" for the opposite mode. This marking has caused confusion among many Stanley garage door opener owners trying to program their 105015 remote transmitter
.

Always carefully check the switch positions on the overhead machine (the powerhead, as it is called), and note which is "off" and which is "on" so you can correctly set the switches in the remote to match the circuit settings. garagedoorsupplyco.com provides free customer technical support on all remotes and for other parts they sell.
