- Simple 4-position rotary dial for each of the 4 ventilation settings
- Easy to install and connect to LUNOS controllers
- Aesthetically pleasing replacement for double-rocker switches
- Decal simply illustrates flow rate at each knob position
- Knob position: 12 o'clock = Off
- Knob position: 1 o'clock = Low
- Knob position: 2 o'clock = Med
