You have there 4 pairs of relay, each use 3 pins:
-COM = the common terminal
-NC = Normally-closed contacts disconnect the circuit when the relay is activated
-NO = Normally-open contacts connect the circuit when the relay is activated
For each pair you may use the COM terminal combined with only one of NC / NO contacts, as required selected application.

To power up the system use a normal 12V dc power supply, pay attention to the correct polarity.
At the moment I don’t have access to supplementary info how the remote buttons operate and control additional features.
