Panasonic - Select Cycler System - Whole House Ventilation System, 8" Duct - SACG2K-08

The SelectCycler System features two modes of operation – ‘Hybrid’ and ‘Balanced’ mode:

Hybrid Mode - The supply damper is open to bring in fresh air. If normal heating and cooling cycles don’t run long enough to meet required ventilation, the controller will also power on WhisperGreen Select™ via the FanConnect wall switch to provide supplemental ventilation.

Balanced Mode - The controller opens the supply damper AND activates the WhisperGreen Select at the same time. If heating or cooling cycle is too short to meet ventilation needs, the controller will also activate the HVAC/AHU.
