The reverse energy is measured and added to the corresponding forward energy. The energy measuring range is from 0 to ****9.**9kWh. (2) RTC An external real time clock realizes the timing and TOU, including calendar programme and day light saving time setting. (3) TOU control It can offer 4set schedules to realize multi-TOU control. The day can be maximally divided int *0 periods with 4tariffs for each schedule. Work-off days can be also programmed in a week. (4) Energy Record It can store energy in billing day of each month. The billing day can be set within 1 to *8 of one month. It may store history energy data for *2 months.
