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.

Product Description

The ST812 is a combined temperature/humidity sensor which is designed for both – desktop use or wall mountable. The device has a local LCD display which either shows the temperature or the humidity. Four buttons allow to switch between minimim, maximum or actual values, humidity versus temperature and Fahrenheit versus Celsius. The device can report its values via Z-Wave and allows to set trigger level for direct control of other Z-Wave devices, when the measured value hits the trigger point. This makes the ST814 a very powerful and flexible tool to measure environmental values and control device within a Z-Wave network.

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.

Quickly clicking three times on the Linking button on the front of the device will enter inclusion mode. Within 1 second, press the Linking button again and hold it until the long signal tone is off. Now the device is set to factory settings.

Safety Warning for Batteries

The product contains batteries. Please remove the batteries when the device is not used.
Do not mix batteries of different charging level or different brands.

Installation

The Temp./Humid. Detector can either be mounted on a wall or can be freestanding on a table. Please consider a most suitable way before mounting/ placing it.

1. Release the Sensor from the mounting plate and the battery cover by removing the fixing screws.

2. Put the 3 * AA 1.5V batteries in the battery compartment.

3. For wall mounting use mount plate and the screws.

4. Refit the device to the back cover and secure with the fixing screw.

5. For table placing insert the stand into the hole on mounting bracket and turn 90 degrees lockwise.

6. Once snapped in place, the detector can be placed on a shelf, table or other surface where the temperature and humidity measurements are desired.

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 that your Z-Wave Controller is in the Inclusion-/Exclusion-Mode. Quickly click three times on the Linking button on the front of the device to confirm the process.

Exclusion

Make sure that your Z-Wave Controller is in the Inclusion-/Exclusion-Mode. Quickly click three times on the Linking button on the front of the device to confirm the process.

3.1 Programming Z-Wave

Z-Wave”s Groups (Association Command Class Version 2)

The Temp./Humid. Detector can be set to send reports to or control associated Z-Wave devices. It supports two association groups with one node support for Grouping 1 and three nodes support for Grouping 2.

Grouping 1 includes POWER_APPLIED, SENSOR_MULTILEVEL _REPORT, ALARM_REPORT and BATTERY_REPORT_COMMAND. Grouping 2 includes BASIC_SET.

Grouping 1

POWER_APPLIED command

Whenever power is applied, it will send ALARM_REPORT command to the nodes of Grouping 1 to inform the devices that the detector is powered up.

MULTILEVEL_SENSOR_REPORT

The detector will emit SENSOR_MULTILEVEL_REPORT to inform the nodes of Grouping 1 automatically its current temperature and humidity. Refer to the section of Z-Wave”s Configuration for settings of auto report configuration.

Low Battery Report

When the battery level of the detector drops to an unacceptable level, the Low Battery icon will appear on the LCD and the detector will emit ALARM_REPORT command to the nodes of Grouping 1.

Grouping 2 (Max. Node = 3)

When the detector is triggered, it will emit BASIC_SET_COMMAND to the nodes of Grouping 2.

Please refer to the table below for the setting of basic set command.

Note:

If the Z-Wave mode is OFF, no command will be sent even the Temp./Humid. Detector has been triggered. If Z-Wave mode is ON and the detector has been triggered, the device will send commands to nodes of Grouping 2.

If the Z-Wave mode reading is 00, it implies no node ID has been allocated by Z-Wave Controller. Please execute inclusion mode as described in the manual.

4. Beep Tone

To set the beep tone, press Select Mode button and select MODE 8. The Beep Tone icon flashes. Press Max. for ON and Min. for OFF. If it is ON, a beep tone will be sounded whenever a button is pressed; 4 continuous beep tones will be sounded for 1 second if the detector has been triggered.

Node Information Frame

The Node Information Frame (NIF) is the business card of a Z-Wave device. It contains
information about the device type and the technical capabilities. The inclusion and
exclusion of the device is confirmed by sending out a Node Information Frame.
Beside this it may be needed for certain network operations to send out a Node
Information Frame. To issue a NIF execute the following action:

Quickly clicking three times on the Linking button on the front of the device will issue a Node Information Frame and keep the device awake to receive configuration commands.

Communication to a Sleeping device (Wakeup)

This device is battery operated and turned into deep sleep state most of the time
to save battery life time. Communication with the device is limited. In order to
communicate with the device, a static controller C is needed in the network.
This controller will maintain a mailbox for the battery operated devices and store
commands that can not be received during deep sleep state. Without such a controller,
communication may become impossible and/or the battery life time is significantly
decreased.

This device will wakeup regularly and announce the wakeup
state by sending out a so called Wakeup Notification. The controller can then
empty the mailbox. Therefore, the device needs to be configured with the desired
wakeup interval and the node ID of the controller. If the device was included by
a static controller this controller will usually perform all necessary
configurations. The wakeup interval is a tradeoff between maximal battery
life time and the desired responses of the device. To wakeup the device please perform
the following action:

Quickly clicking three times on the Linking button on the front of the device will issue a Node Information Frame and keep the device awake to receive configuration commands.

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

1. Make sure a device is in factory reset state before including. In doubt exclude before include.
2. If inclusion still fails, check if both devices use the same frequency.
3. Remove all dead devices from associations. Otherwise you will see severe delays.
4. Never use sleeping battery devices without a central controller.
5. Dont poll FLIRS devices.
6. 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.

Configuration Parameters

Z-Wave products are supposed to work out of the box after inclusion, however
certain configuration can adapt the function better to user needs or unlock further
enhanced features.

IMPORTANT: Controllers may only allow configuring
signed values. In order to set values in the range 128 … 255 the value sent in
the application shall be the desired value minus 256. For example: To set a
parameter to 200 it may be needed to set a value of 200 minus 256 = minus 56.
In case of a two byte value the same logic applies: Values greater than 32768 may
needed to be given as negative values too.
