1. Introduction

Z821, the ZigBee compact-size multi-port CT (current transformer) type power meter, acts as a router in ZigBee

network. Z821 is the only one for independent monitoring and measurement of up to 7 single-phase AC outlets in

the world. It is fully IEEE 802.15.4 compliant and utilizes 2.4GHz ISM band. With high measurement accuracy

±0.5%~1%, Z821 has the most advanced performance and is an ideal product to know the whole power and energy

consumption such as load current, load voltage, power, or energy.

What is ZigBee?

ZigBee is a short range wireless transmission technology based on IEEE802.15.4 standard and supports multiple

network topologies such as point-to-point, point-to-multipoint, and mesh networks. It is defined for a

general-purpose, cost-effective, low-power-consumption, low-data-rate, and easy-to-install wireless solution for

industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation

and home automation, etc.

3. Specification

Fully IEEE 802.15.4 compliant (ZigBee Pro)

Utilizes 2.4GHz ISM band; up to 16 channels

Power supply: 100~240VAC, 50/60Hz

Power consumption: 18mA/230VAC, 1.2W

Basic accuracy: <±1%

Measuring Range: 7 single CTs; 60A x 1/ 30A x 6

Transmission range: Up to 280 meters

Easy installation and configuration

4. Installation

This device is NOT truly waterproof/ resistant and is for indoor use.

This equipment must only be installed and serviced by qualified electrical personnel.

Turn off all power supplying equipment before working on or inside the equipment.

Always use a properly rated voltage sensing device to confirm power is off.

Beware of potential hazards, wear personal protective equipment, and carefully inspect the work area for

tools and objects that may have been left inside the equipment.

Install the power line (live wire) which you would like to measure with the Primary side. Next, connect the

Secondary side to Z821 (k to k; l to l).

Z821 power wire installation is as shown below, AC-L connected to live line, AC-N then N line

Install CT terminal of the black wire and white wire as below diagram:

CT terminals of the L and K polarity distinction are as follows:

While connecting, use two wires (the color is white and black, representing the k and l terminals) of the secondary

side of the CT to correspond to the character markers (k and l) on the Z821 housing.

The AC power line goes through the CT center hole, and the CT K-side (injection surface) towards the power

supply side, L side (character face) towards the load side.

Distribution box and antenna installation as follows:

The circuit is as follows after installation:

5. Setting up Z821

5-1. Join the ZigBee Network

After Z821 is turned on, it will search for an existing ZigBee network and send a request to join the network

automatically. While Z821 is under the coverage from a coordinator or a router whose permit-join feature is

enabled, Z821 will be permitted to join the network.

Step1. Enable the permit-join function (valid for 60 seconds) of a coordinator or a router (please refer to

the user manual of the coordinator or the router to enable the permit-join feature).

Step2. Turn on Z821. It will start to search and join the network.

Step3. The indicator will flash green once when it finds out a network to join.

Step4. The network indicator will stay green after it is joined successfully. Otherwise, the indicator will

be off.

5-2. Permit-Join

Z821 acts as a router in ZigBee network. After the permit-join feature is enabled, it allows other devices to join

the network.

Step1. Press the Binding Key. The permit-join feature will be enabled for 60 seconds.

Step2. Within the period of 60 seconds, the network indicator flashes once per second.

Within the period of 60 seconds, press the Binding Key again to turn off the permit-join.

5-3. Power Measurement

Z821 is an ideal product to know the whole energy consumption of the building; even to measure every sub

power meter to recognize how much energy is consumed by appliances in your home/office. Through ZigBee

technology, users are able to acquire the data, like current, voltage, power, or energy, from Z821 wirelessly.

5-4. CT/ N Wire/ L Wire Connection Error Notification

When the connection of CT or N/L wire is incorrect, the Status Indicator will keep flashing red. In this case,

we will get the wrong power consumption data.

5-5. Reset Power Consumption Summation

To reset the power consumption data, please follow the steps:

Step1. Press and hold the Binding Key for 20 seconds. The status indicator will flash 4 times.

Step2. After releasing the Binding Key, press the Match Key within 2 seconds to complete the reset.

5-6. Restore to Factory Setting

To restore it to factory setting, please follow the steps:

Step1. Press and hold the Binding Key for 15 seconds. The status indicator will flash 3 times.

Step2. After releasing the Binding Key, press the Match Key within 2 seconds to complete the restore.

6. Home Automation Clusters for Z821

A cluster is a set of related attributes and commands which are grouped together to provide a specific function. A

simple example of a cluster would be the On/Off cluster which defines how an on/off switch behaves. This table

lists the clusters which are supported by Z821.

This lists the attributes of the basic information.
