85 85  Phase dimming DIN-1DIMU4 modules are installed inside DIN panels, which are typically located inside an electrical room or an MDF/IDF closet.

87 -Each DIN-1DIMU4 module has four dimming outputs which all share a common line input. Each output has an LED to indicate current output status (on or off) and a button that can be used to toggle the output. Press this button once to turn the load on or off, and then press and hold this button to raise or lower the output. While dimming, the output percentage is indicated on the LCD screen on the module. Above the toggle button and load indicator LED, each output also has LEDs to indicate current phase dimming mode. Available phase dimming modes are: forced forward, forced reverse, auto-detect, and non-dim (switched). When in auto-detect mode, the "Auto" LED will be lit alongside either the "FWD" or "REV" LED to indicate which type of dimming has been detected. Below the phase mode LEDs is a recessed button which can be pressed to cycle between available phase dimming modes.
87 +Each DIN-1DIMU4 module has four outputs which all share a common line input. Each output has corresponding LEDs to indicate current output status and current phase dimming mode. Each output also has a corresponding button which can be used to toggle each channel independently, and holding the button will cycle dim the phase dimming output for that channel.

93 93  Below is a table of actual phase dimming readings at various percentage brightness for some Crestron lighting controllers. Measurements were taken from 120V modules using a true-RMS meter (note that the oscilloscope graph appears high because it is reading the peak voltage).
