Eco-Mode is a feature built into Mysa thermostats that helps boost energy savings. How it works is, two hours after a set point change Mysa will adjust itself into Eco-Mode. At that time Mysa will lower the set temperature by 0.5 Deg C, thus saving energy. The change in temperature is virtually indistinguishable to most people but it will dramatically affect energy savings. Eco-Mode comes pre-enabled on all Mysa thermostats running firmware version 1.1.13 or newer.
