For added sustainability (and a lowered electric bill) the Swash LT99 features an optional eco mode setting. In this mode, seat temperature will lower to “low” after 10 minutes of non-use. If the seat temperature is already set to “low” or “off,” there will be no change. Turning off eco mode will allow the seat to stay at “medium” or “high,” even during extended periods of non-use.
What is eco mode?
