Welcome. My name is ***** ***** would be glad to assist.
Based on information I can I find, it may very well be possible to use the 371 LM with the commercial operator.
You need to see which program situation your operator has been wired for and designed by the installer.
You will note on my picture posting, that 2 modes will not work with single button remotes, but it definitely states that the T logic is capable of the Security +
I would give a try with the 371LM and see if their programming works.
If it doesnt, then I would agree with the previous experts analysis as this is the only information that shows it may be possible. The compatibility chart is for residential openers and so there are always possibilities with commercial operators and the remotes.
Would appreciate a post after the attempt so that I may keep this information in my database for future reference or just discard it all together.
If it doesnt work, then the previous expert definitely deserves credit for their posting, so keep this in mind, as I am going by Chamberlains published information as well.
