Qubino 1d wiring help


I’ve just bought a Qubino 1d to control a small 240v roller shutter. The controller for the shutter has three terminals, one common and one up and one down, normally this would be connected to a button on the wall but I’ve always just used a radio remote.
Can someone tell me how to connect to the Qubino to act as a momentary switch and use the common connection, please?
I have no problem wiring up the 240v part.
