Ki - Electronic Thermostat for Smart Home
SKU: STZW402+
Quickstart
This is a
Make sure the Z-Wave hub is in the include mode (Refer to your Z-Wave hub instruction manual).
To add (include) the thermostat to a Z-Wave network, enter the Menu 1 (Z-Wave menu) and select “Onâ€. Then press the UP and DOWN buttons to start the inclusion process. During inclusion, “On†will be blinking and the connectivity icon will be animated in an increasing pattern. When the inclusion process has been completed, On will be displayed solid. If an error occurs, “Err†will be displayed for 3 seconds then the screen will revert to “Off†selection.
Important safety information
Please read this manual carefully. Failure to follow the recommendations in this manual may be dangerous or may violate the law. The manufacturer, importer, distributor and seller shall not be liable for any loss or damage resulting from failure to comply with the instructions in this manual or any other material. Use this equipment only for its intended purpose. Follow the disposal instructions. Do not dispose of electronic equipment or batteries in a fire or near open heat sources.What is Z-Wave?
Z-Wave is the international wireless protocol for communication in the Smart Home. This device is suited for use in the region mentioned in the Quickstart section.
Z-Wave ensures a reliable communication by reconfirming every message (two-way communication) and every mains powered node can act as a repeater for other nodes (meshed network) in case the receiver is not in direct wireless range of the transmitter.
This device and every other certified Z-Wave device can be used together with any other certified Z-Wave device regardless of brand and origin as long as both are suited for the same frequency range.
If a device supports secure communication it will communicate with other devices secure as long as this device provides the same or a higher level of security. Otherwise it will automatically turn into a lower level of security to maintain backward compatibility.
For more information about Z-Wave technology, devices, white papers etc. please refer to www.z-wave.info.

Prepare for Installation / Reset
Please read the user manual before installing the product.
In order to include (add) a Z-Wave device to a network it must be in factory default state. Please make sure to reset the device into factory default. You can do this by performing an Exclusion operation as described below in the manual. Every Z-Wave controller is able to perform this operation however it is recommended to use the primary controller of the previous network to make sure the very device is excluded properly from this network.
Reset to factory default
This device also allows to be reset without any involvement of a Z-Wave controller. This procedure should only be used when the primary controller is inoperable.
The thermostat may be manually reset to its factory state. When this is performed, all parameters are reset to their default values and the thermostat is removed (excluded) from the Z-Wave network. To reset the thermostat to its default state: - Enter the advanced settings - Enter the °STELPRO menu (menu 7) - Navigate to the “def†screen using the UP or DOWN buttons. - Enter the “def†menu by pressing the UP and DOWN buttons for less than 3 seconds - Select “yes†and confirm the selection by pressing the UP and DOWN buttons for less than 3 seconds. If the thermostat was added (included) in a Z-wave network, it will send a ‘’device reset locally’’ notification. The thermostat will then reset itself. Please use this procedure only when the network primary controller is missing or otherwise inoperable.
Safety Warning for Mains Powered Devices
ATTENTION: only authorized technicians under consideration of the country-specific installation guidelines/norms may do works with mains power. Prior to the assembly of the product, the voltage network has to be switched off and ensured against re-switching.
Inclusion/Exclusion
On factory default the device does not belong to any Z-Wave network. The device needs to be added to an existing wireless network to communicate with the devices of this network. This process is called Inclusion.
Devices can also be removed from a network. This process is called Exclusion. Both processes are initiated by the primary controller of the Z-Wave network. This controller is turned into exclusion respective inclusion mode. Inclusion and Exclusion is then performed doing a special manual action right on the device.
Inclusion
Make sure the Z-Wave hub is in the include mode (Refer to your Z-Wave hub instruction manual). To add (include) the thermostat to a Z-Wave network, enter the Menu 1 (Z-Wave menu) and select “Onâ€. Then press the UP and DOWN buttons to start the inclusion process. During inclusion, “On†will be blinking and the connectivity icon will be animated in an increasing pattern. When the inclusion process has been completed, On will be displayed solid. If an error occurs, “Err†will be displayed for 3 seconds then the screen will revert to “Off†selection.Exclusion
Make sure the Z-Wave hub is in the exclude mode (Refer to your Z-Wave hub instruction manual). To remove (exclude) the thermostat from a Z-Wave network, enter the Menu1 (Z-Wave menu) and select “Offâ€. Then press the UP and DOWN buttons to start the exclusion process. During exclusion, “Off†will be blinking and the connectivity icon will be animated in an decreasing pattern. When the exclusion process has been completed, Off will be displayed solid. If an error occurs, “Err†will be displayed for 3 seconds then the screen will revert to “On†selection.Quick trouble shooting
Here are a few hints for network installation if things dont work as expected.
- Make sure a device is in factory reset state before including. In doubt exclude before include.
- If inclusion still fails, check if both devices use the same frequency.
- Remove all dead devices from associations. Otherwise you will see severe delays.
- Never use sleeping battery devices without a central controller.
- Dont poll FLIRS devices.
- Make sure to have enough mains powered device to benefit from the meshing
Association - one device controls an other device
Z-Wave devices control other Z-Wave devices. The relationship between one device controlling another device is called association. In order to control a different device, the controlling device needs to maintain a list of devices that will receive controlling commands. These lists are called association groups and they are always related to certain events (e.g. button pressed, sensor triggers, ...). In case the event happens all devices stored in the respective association group will receive the same wireless command wireless command, typically a 'Basic Set' Command.
Association Groups:
| Group Number | Maximum Nodes | Description |
|---|---|---|
| 1 | 1 | Z-Wave Plus Lifeline The following reports are sent via the Lifeline : - Basic Report - Device Reset Locally Notification - Thermostat Mode Report - Thermostat Setpoint Report - Sensor Multilevel Report - Thermostat Operating State Report |

Explanation of Z-Wave specific terms
- Controller — is a Z-Wave device with capabilities to manage the network. Controllers are typically Gateways,Remote Controls or battery operated wall controllers.
- Slave — is a Z-Wave device without capabilities to manage the network. Slaves can be sensors, actuators and even remote controls.
- Primary Controller — is the central organizer of the network. It must be a controller. There can be only one primary controller in a Z-Wave network.
- Inclusion — is the process of adding new Z-Wave devices into a network.
- Exclusion — is the process of removing Z-Wave devices from the network.
- Association — is a control relationship between a controlling device and a controlled device.
- Wakeup Notification — is a special wireless message issued by a Z-Wave device to announces that is able to communicate.
- Node Information Frame — is a special wireless message issued by a Z-Wave device to announce its capabilities and functions.
