Understanding Tunable White Control Modes for the Echoflex ELED2 Tunable White Dimming Controller

Modes

Dim-To-Warm

• What is linked: at least 1 switch to channel 1, nothing to channel 2 or 3.
  • Can also have sensors linked to channel 1 in addition to switch.
• Functionality: joint control of intensity and CCT via the same switch.
  • Ex: Press and hold up on switch, intensity increases and CCT becomes cooler.

Explicit Color Control

• What is linked: at least 1 switch to channel 1, at least 1 switch to channel 2, nothing to channel 3.
• Functionality: explicit control intensity and CCT via different switches. 
  • Ex: Press and hold up on switch linked to channel 1, intensity increases. Press and hold up on switch linked to channel 2, color becomes cooler.
  • Note on CCT control: single tap of 'on' or 'off' will incrementally ramp the color cooler/warmer, press and hold will continually ramp as long as button is held.

Automated Color Tuning

• What is linked: TAP41 is linked to channel 2 for closed loop CCT control. TAP41 is linked to channel 1 and 2 for both CCT & Intensity control.
  • Recommended that occupancy sensor or switch is linked to channel 1 for relay control. 
• Functionality: Automated control of intensity and CCT.

Characterized Color Tuning

• What is linked: at least 1 FLS-41 to channel 3.
• Functionality: Color tunable output modulates based on the value provided by the linked FLS-41.
  • Note on characterized color tuning: This operation does require the fixture's characterized specifications for the 0–10 V channel be defined with the controller’s configuration.
    • Example: A fixture is used that maps a range of 3200–6000 K across the 1–10 V range. These values are pre-commissioned with the ELED2-BU or ELED2H-AU at the factory. The color tunable output modulates based on the value provided by a linked FLS-41 sensor on the set point value.
