ECO Clima Control is a weather-monitoring clock that keeps you updated on temperature and humidity both indoors and out. You can ensure supreme comfort at home, whilst protecting our environment by minimizing waste from the consumption of multiple batteries, as well as saving energy.This ECO Clima is designed with energy saving concept that converts solar energy into its source of power via a solar panel. By simply lifting up the solar panel and facing it towards the sun for a few hours, this enables it to capture and store the energy to recharge the eco batteries without using any of its main supply. The indication light at the front of the case will show you the power status and blink to alert you to recharge the solar power when the battery needs recharging.This ECO Clima Control comes with 2 sensors included, but it is able to work with maximum 4 sensors to display temperature and humidity of different rooms in a house. With its clear and elegantly designed display, you and your family are not only prepared for mother nature, you’re able to protect her with the solar panel power source.
