0x0000 server
Basic
Provides basic information about the device, such as the manufacturer ID,
vendor and model name, stack profile, ZCL version, production date,
hardware revision etc. Allows a factory reset of attributes, without the device
leaving the network.
Configure Device Operation Mode through Zigbee
Since Zigbee does not have away mode, the attribute Occupancy (occupied or unoccupied) of Thermostat
(0x0201) and attribute Occupancy of received OccupancySensing (0x0406) are required to judge whether
it is away mode.
1) if the device receives other devices’ or the gateway’s report: the Bit 0 of the value of attribute
Occupancy (0x0000) of OccupancySensing Cluster (0x0406) is 1, which means occupied, then the
operation mode of the thermostat, the attribute SystemMode(0x001c)=0x04(heat) of Thermostat (0x0201),
meanwhile the value of attribute Occupancy (0x0002) of Thermostat (0x0201) is 0. It means the Away Mode
is activated, and the thermostat UI will display .
2) if the gateway send command to modify the attribute SystemMode(0x001c) of Thermostat (0x0201), the
thermostat will quit Away Mode. Meanwhile the value of attribute Occupancy (0x0002) of Thermostat
(0x0201) is 1.
3) The proprietary attribute 0x2002(Manufacturer Code=0x1224) of the cluster 0x0201 can be modified to
configure whether it is away mode or at home.
Note: Away Mode uses attribute UnOccupiedHeatingSetpoint to set temperature.
Other modes uses attribute OccupiedHeatingSetpoint to set temperature.

The Time cluster is a general cluster for time it is based on a UTC time in seconds since 0 hrs 0 mins 0 sec on
1st January 2000. Refer to [Z2] for ZigBee specification of the time cluster.
The metering device will use this clusters as a client – provided that a suitable Time Server is available on the
network (most likely on the Gateway/concentrator)
If the device has bound TIME cluster, then the device will acquire the value of Local Time (0x0007)
spontaneously.

2. Remove the display unit and backplate of the device from the packaging.
3. FIRST ENSURE THE POWER IS OFF at the main circuit breaker, and then test the wires with a probe or multimeter to verify.
Insert the power and heater wires to the correct device terminals by inserting a small Phillips-head screwdriver in the slot beneath
each terminal to open. Follow the connection diagram and instructions below:
• Power wires: connect Line & Neutral wires to L & N terminals labeled “IN”
• Heater wires: connect Line & Neutral wires to L & N terminals labeled with “heating element” graphic
WARNING: The wire size shall be in compliance with regulations, using wire with insufficient size for big load will cause
severe temperature rising.
This device should be installed by a licensed electrician in a manner that conforms to local regulations and building codes.
Provide these instructions to the licensed electrician who is installing the device.
WARNING: Electrical power must be switched off during installation.
1. Placement of the device is of utmost importance for proper operation and must be away from sunlight and sources of direct
heat. We recommend installing the device approximately 1.5 meters above the floor.

Troubleshooting:
1. External (floor) sensor temperature tolerance is too high
Possible reason: the selected sensor type is not correct
2. The gateway can not set temperature when energy save mode is selected
The temperature schedule of auto mode (energy save mode) is not configured correctly
3. Current temperature is not executed when away mode is selected
Check whether away mode time is set as 0 or within valid time range
4. Over heat alarm when power on the device
Possible reason: the set sensor type is not correct or sensor type after factory reset is not correct
5. Device time is not the same as the gateway controller after added to the network
Set the device time and time zone manually after added to the gateway network
6. The tolerance of the indoor temperature sensor is high after powered on
Possible reason: due to temperature effect, we need to wait for a while
