#6: Power and energy
consumption
The Wall Plug allows to monitor the active power and energy con-
sumption. Data is sent to the main Z-Wave controller, e.g. home
Center.
Measuring is carried out by the most advanced micro-controller tech-
nology, assuring maximum accuracy and precision (+/- 1% for loads
greater than 5W).
Power and energy are reported according to parameters 11-15.
For loads under 5W power is reported for every 0.2W change.
For uSB port power is not reported for loads under 0.4W.
Electric active power
- power that energy receiver is changing into a
work or a heat. The unit of active power is Watt [W].
Electric energy
- energy consumed by a device through a time
period. Consumers of electricity in households are billed by sup-
pliers on the basis of active power used in given unit of time. Most
commonly measured in kilowatt-hour [kWh]. One kilowatt-hour is
equal to one kilowatt of power consumed over period of one hour,
1kWh = 1000Wh.
Resetting consumption memory
:
Wall Plug allows to erase stored consumption data (turning it off/on
or removing it from the socket will not erase consumption):
1. Make sure the device is powered.
2. Press and hold the button.
3. Release the button when the LED frame glows green (1st menu
position).
4. Press the button briefly.
