Creasol UniRec1 universal receiver can be connected to the SCS SENTINEL board ACCESS-602 to allow controlling that board by another kind of remote control, for example to use a single remote control to open more than one automation.
Connect one Power Supply wire to terminal 11
Connect the other Power Supply wire to terminal 12
Connect Switch+ to terminal 4
Connect Switch- to terminal 3

Then, program the receiver to learn one or more remote controls, and check that it works.
If it does not open the automation, exchange the connections to terminal 4 with terminal 3, and vice versa.
