What is the difference between the ECN and ECN Zero accounts at ForexTime?

According to the title of this question.
At ForexTime Broker, there are two types of ECN accounts. Namely, regular ECN account and ECN Zero account. I feel like there is not enough information on their website, what is actually the difference between the two? What are the advantages and disadvantages?

One more question related to this. On the official website, it is stated that ECN Zero account is an ECN account without commission, but looking at the spread information, it seems as wide as a cent account. What does this mean? Is ECN Zero really an ECN type or not? Please provide information. Thank you
