Any period of time in a group of a plurality of sets of timing of the current time period, the system enters the working state. Work within the timing period, the status screen is displayed automatically. In the period of time in commuting to work outside the state. Each group comprises a turn-on time period (hour, minutes) and a closing time (hours, minutes) may be set or modified when the three control period, divided by the setting operation and the current time. The user can set different time different temperature ranges.

Continue to promote the comprehensive management of dust pollution, coal-fired pollution control to strengthen and deepen the industrial pollution control and related fields, etc., which are from governance "Xining City 2018 air pollution comprehensive management action plan." Xining City, the official launch of construction on the "Xining blue" and maintain the action. Aspects of dust, industrial pollution, coal pollution will increase management and control, to develop specific control measures for building a better Xining efforts.

Since the launching of "Xining blue" action in the coal-fired pollution control, Xining City has accumulated more than 3,000 tons of steam "coal to gas," the task of governance, the main city of the city "coal to gas" campaign to take the lead. With the further implementation of the Blue Sky Project, Xining substantial increase in utilization of clean energy, significantly improve air quality of the environment, it has been among the five northwestern provinces in the forefront of the capital city.

Taking into account the special Xining City, Qinghai-Tibet Plateau is located in the geographical location, the winter heating season is longer, coal dust is an important source of winter air pollution, while heating pipeline dredge more difficult, the implementation of the transformation plan will face difficulties pipeline reconstruction. To effectively improve urban air quality since 2013, Xining City, carry out a comprehensive "coal to gas" governance by supporting comprehensive measures upgrading natural gas pipeline network, such as the yellow car out of standard co-ordinate the promotion of winter clean, safe and efficient heating, achieved within the natural gas pipeline network coverage coal to gas works full coverage.

To promote the implementation of clean energy projects, Xining City, expand the scope of the ban on coal to 166 square kilometers, and implementation of the "coal to gas" in the natural gas pipeline network range, achieved in the area of ​​coal-fired boiler "cleared." Increase coal trading market will be rectified, completed a five coal market and coal two 49 business outlets, effectively reducing the use of inferior coal pollution on the surrounding environment.
