Hi Neil,
The relay is there to switch the 24v output from the Libra to a dry contact output, the H3D timer requires a control input of 0v dry contact. This then initiates the timer to allow the power to the lights for whatever amount of time you set it to when programming it via the dials on the H3D.
Hope this helps.
