The description on the function "Activate for 0.5 seconds, controlled by button #2 (or by upper...) is misleading.
The relay is only on for 0.5 seconds when using the button. Not both buttons in the pair.
Setting to button #1/upper pair only activates the relay on button1 - not button2
vice versa; Setting to button #2/upper pair only activates the relay on button2 - not button1
