This is the ungraded receiver kit for MERLIN Profit 230T opener and remotes M802, M832, M842 and M872, which enables the use of newer and smaller remote controls. This conversion kit comprises one add-on receiver and two clean design, handy remote controls.

Installation of the receiver couldn't be easier. Just hook up the three wires onto the screw terminals on the back of your opener as shown in the diagram below. Then it's done! The new remotes have already been pre-programmed so you can use them straight away! Plus, your existing remote will still work.

We will send instruction along with the receiver kit.

Attention :

If your motor does not have the 5 terminals as show below (or sometimes it has 4 terminals, it is also fine to use MK502), then please purchase MK902 which comes a power adaptor. Please seek item MK902 for installation instruction. It is also very easy to install.

Good to know :

Extra remote control is available, it is a MK330. Up to 30 remotes can be coded to this receiver, more than enough!
