No unfortunately there is no 2-way pushbutton dimmer in the Saturn/ Saturn ZEN Series. However this function can be obtained through the use of our Wiser Micro Module Dimmer.
This setup works by a Saturn/ Saturn ZEN (60 Series) momentary press mechanism (60PBBP) is connected to the Wiser Micro Module (CLP5010-0001) which is "floating" in the wall cavity. This setup allows a short press to turn on and off the dimmer while a long press will ramp up or ramp down the dimmer.
Please see the attached wiring diagram.
