The Fresco Remote Button station (FCS RB) supports a button mode or function for Toggle behavior and Toggle/Raise/Lower behavior.
The toggle behavior will alternate between On and Off for the configured control point: Zones will toggle on and off or 0% and 100%. Links will link and unlink respectively.
The toggle/raise/lower behavior will function as above with the alternating action, but upon pressing raise or lower after the toggle will begin changing the level in the respective direction based on raise or lower being pressed. The raise/lower should function naturally to the user.
