Question about intertechno IT-3500L Set

Yes, you can program the IT-3500L (Type 12) remote control to work with existing ITLR-3500 sockets, as these two products use the same Intertechno radio protocol and are compatible with each other. To do this, simply pair the remote control with the socket by following the learning procedure described in the ITLR-3500 socket manual (usually by pressing the learning button on the socket, then sending a signal from the remote control). No additional settings are required, as compatibility is ensured by the manufacturer.
