To change the dimmer doubling mode for a circuit in a Legacy Unison DR rack, you must use the "hidden" configuration menu.
Steps to Solution
- Access the configuration menu on the processor by pressing just above the Unison logo with the raised red error indicator for three seconds.
Press "Unison Menu activate" for 3 seconds to access the configuration menu.
- Scroll up or down to the [Cnfg] menu and press Enter
- Use the up or down arrows to select the circuit you wish to modify
- Press Enter repeatedly until you see the Mode menu. Your options are DD_On and DD_Off.
Note: Only circuits configured as a standard 120V dimmer module (D20, D15, etc.) with a load type of Incandescent will allow you to toggle dimmer doubling on or off.
