This rotary switch was developed by the 475 team to address requests from LUNOS e2 and eGO customers:
• Avoids the Which Switch Is Which? question
• Aesthetically pleasing
• Simple 4-position rotary dial for each of the 4 ventilation settings
• Easy to install and connect to LUNOS controllers
Rising to the challenge, Phil combined the same functionality achieved by the double-rocker switch control, including summer ventilation mode and deactivation of the filter warning light, into one rotary switch. With this new rotary switch, you can easily achieve all four ventilation settings by rotating the knob to the right.

(Assume a clock face)
• 12:00 = Off
• 1:00 = Low
• 2:00 = Med
• 3:00 = High

Additionally, moving from Low to Med and back to Low again (within 3 seconds) it will put the system into summer vent mode (ventilation without heat recovery). Repeat those actions to transition out of summer vent mode, and back to heat recovery mode again.
