at this time, if the power is turned on, the temperature controller will command the electric heating pipe to continue heating the new cold water e to the influence of the supplementary cold water, Far behind the rate of consumption of hot water; It can be understood that whether the cold water supplied from the lower part is heated or not, the original hot water needs to be stopped after it is consumed, and the water in the bucket is heated to the shared temperature.
the size of the equipment capacity of the water storage electric water heater is set according to the number of users. That is to say, whether the power supply is connected when the appropriate water heater is prepared and used is not a critical problem. When the capacity of the equipment is too small and the usage is too large, it is still time to save the Department's expectation to use hot water and power on heating at the same time.
in addition, the capacity of 60 liters and the temperature setting of hot water in the barrel generally need to be 65-75 degrees, and it is enough to mix cold water to the appropriate temperature when using. All manufacturers of regular brands are extremely serious about the safety problem of electric leakage. They set up electric walls, leakage protection circuits, etc. when electric appliances leak, they will cut off the power supply and protect them; The user must have a qualified grounding protection line is the main link. If there is no grounding line, it is safe to disconnect the power supply when using. For reference only

doesn't match, because Facebook has great ambition, but it has great disadvantages. It doesn't pay attention to its own development, and it pays more attention to its interests
Facebook is ambitious. It will continue to introce new technologies on desktop and mobile devices, and these new procts and applications will be promoted all over the world Facebook is not satisfied with its ability to communicate and interact on social networks, information publishing and Internet. It seeks to use its huge global network and user base to expand penetration to other areas and gain greater benefits and influence< however, Facebook has many problems, especially in information security, which has been widely criticized
it is a kind of digital currency based on Facebook social network and global user group, which is actually a super currency. Second class sovereign currency. Please click the input image to describe a lot of analysis and comments. If Facebook's "Libra currency" project is implemented, it will not only have a huge impact on the global digital economy (especially Internet Applications), but also may subvert the banking instry and seriously affect fiat money countries' credit currencies and sovereign currencies will face a series of other problems, and the consequences are unimaginable
Today (April 10), Congress released a of his testimony. Among them, Zuckerberg took responsibility for Facebook's numerous failures in the past few years and promised to do better
"now it's clear to me that we don't have enough power to prevent these tools from being used to harm others." In his testimony, Zuckerberg said, "it's a huge mistake that we don't know enough about our responsibilities, such as making false news, foreign interference in elections, hate speech, developers and data privacy issues. It's my fault, too. I'm sorry. I created Facebook and I run it, so I have to be responsible for what's going on in this community. "
In conclusion, Zuckerberg said, "my priority has always been to achieve my social mission: connect people, build communities, and bring the world closer together. As long as I'm running Facebook, advertisers and developers will never be on top of that mission. " Zuckerberg will testify on Capitol Hill twice this week and on the U.S. Senate justice and Commerce Committee. Facebook has been questioned after it was exposed that Cambridge analytics, a political consultancy, improperly obtained personal information from as many as 87 million Facebook usersIn two days of nearly 10 hours of congressional hearings, Zuckerberg said a sentence many times: "I will let my team reply to you."
According to the April 11 daily report, Zuckerberg told legislators 40 times that he had no answer on hand and would reply to them later. This means that one-third of the US legislators involved in the Zuckerberg question did not get an answer immediately
5, how many "like" and "share" keys are there
democratic Congresswoman Debbie Dingell asked Zuckerberg to provide data on how many "like" and "share" buttons there are on Facebook
she said, "it has nothing to do with whether you have a Facebook account. With these tools, Facebook can collect information from all of us. "
according to the BBC report, there are buttons everywhere to encourage you to like or share on Facebook“ After "like", Facebook can track users on the page, not only for Facebook itself, but also for advertisers. Users' likes provide more data for advertisers
if we can count the number of all the buttons on the network, the number will be hundreds of millions. Hundreds of millions of Facebook pages can track users' activities outside Facebook through their likes
Recently, Mark Zuckerberg, founder and CEO of Facebook, was questioned by members of Congress in the United States on the data leakage incident involving 87 million users of Facebook. Zuckerberg was questioned by nearly 100 members of Congress for 10 hours in two days
Before this question, the Wall Street Journal predicted that the previous scandal might trigger new legislative measures in Washington, that is, more stringent laws to protect personal data. But Zuckerberg can now rest assured that senators in Congress are not asking too hard questions. In the question and answer session, senators raised questions about how Facebook collects data, how long to keep it, and how to apply it to advertising display. Although these questions are concerned by the American public now and are very important, as some media pointed out, they can be found by searching, and there is no need to waste several hours in the hearing
