Dimmer Curves
There are three available dimmer curves that can be set on the dimmer. These curves can only be set
through the RDM interface.
• ETC Modified Square - A more uniform response to control level changes. This is set as the
default curve.
• Preheat - Same as Modified Square but allows for a minimum level to be set to the curve to
maintain a warm lamp, reduce inrush and lengthen lamp life.
• Linear - matches control level increase to dimmer voltage 1:1.

The ES750 can ONLY be wired to tungsten lamps. Wiring to any other load type will
cause dimmer failure.
To maintain a correct dimmer curve, the dimmer must have a minimum load of 100W.
