How old is your Monsoon? From the pump station this LW4000 is originally from the 1990's. The bay signs and the Rain-X decal are both a more modern upgrade.
A couple of things to check would be to open the
door to the control cabinet (known as the J0) and look at the computer mounted to the
door. If it is an A-4000 controller you will need to upgrade that. If it is an A-5000 controller then pull the cover off and look for a chip along the bottom left with the software version number. An A-5000 equipped with version 20 or higher, will have the laser minder programming installed and will not require a
PDQ distributor to unlock the system option number. It will also already have the programming for Triple Foam. You may have to change the plumbing number to see it.
Just my 2 cents, but unless your Monsoon is older than the LW4000, I would not look to replace it. Have you considered selling it or parting it out?
