Main Functions
(1) Active energy measuring
It can measure total energy and energy of every tariff. The reverse energy is measured and added to the corresponding forward energy. The energy measuring range is from 0 to 99999.999kWh.
(2) RTC
An external real time clock realizes the timing and TOU, including calendar program 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 10 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 28 of one month. It may store history energy data for 12 months. All data may be accessed via personal
Computer(PC) or hand hold unit(HHU).
(5) Display
It can display by LCD indicator during both power supply and power failure. It supports
Automatically cyclic display mode and button pushing display mode. Display items can be set by
User via PC or HHU. If power failure lasts 7 days continuously, display will be turned off and can be awaked by infrared controller or pushing button.
