Liftmaster

I have a Chamberlain Liftmaster model# h5011L2R (NS), with a three position switch on the wall. My queastion is, can the door be lowered by only pressing the down button once (instead of holding it) Someone I spoke to said it could be done through the wiring.Any help would be appreciated, Thank you

It can be done through the wiring. If you call Liftmaster, they will be happy to explain the wiring to you. I suggest being in front of the unit when you call, so that you can do the wiring with them on the phone.

If you don't want to do that, the complete wiring diagram is on the inside of the cover.

Oh that's why i didn't recognize it. I was thinking residential not commercial. If it is the model I'm thinking of, Model MT5011 (and this is on the newer models which came out in the last year or two) you just remove the red wire on terminal #12 and move it to terminal #2. But keep in mind that is sort of a safety feature so someone has to stand there and hold the close button, thus watching the door so it is not closed on anything

Well I double checked the model # and it is H5011L2R(NS)
The wiring diagram on the cover says Logic 2.0 Rev B
Terminal # 12 and 11 are empty there is a jumper between #2 and 3 and coming from the switch through the conduit are two red wires not hooked up to anything

I hope this will help you help me Thank you

I'm not sure on this, because I can't match that exact model # with liftmasters web site. If I had the wiring schematic or the manual, I would be 100%. the model "H" which is a "Hoist " operator calls for you to move some dip switches on the logic board
Go here to this site (it is a PDF document so you will need adobe acrobat reader installed on your PC) http://www.liftmaster.com/pdfdocs/A13908m.pdf
scroll down to page 16. You want the "B2" wiring. Basically there are 4 dip switches they need to be set all in the down position or OFF.
