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.

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.

By pressing buttons Right and Center (down and confirm) for 20 seconds,” the thermostat will perform a complete factory reset.

Product Usage

**

Principles of regulations
Regulation Using Floor / External sensor (F, A2 or A2F-Mode)**

The thermostat uses temperature readings retrieved from the internal sensor or external wired sensor to regulate heating. When you have chosen a setpoint temperature, the thermostat will use an internal hysteresis to regulate the temperature. This hysteresis is adjustable.

“

Using Internal sensor (A-mode/AF mode)

If you have a set point of 20″°C, the thermostat will use the full power until the temperature is 19″°C. The thermostat will then begin to regulate the output from 19″°C with a 75% duty cycle until it reaches 19,25″°C. When the temperature has reached 19.5″°C the thermostat will use a 50% duty cycle, until it reaches 20″°C, then the thermostat turns off and repeats the process. For example, at a 75% duty cycle it will turn ON for a total of 90 minutes and OFF for 30 minutes.

Programming the thermostat

To activate the programming mode, press Center (confirm) for 10 seconds. The display will show OFF. You are now in programming

mode. To scroll up and down in the menu, use buttons 1 and 3 (left

and right) to navigate. To enter the submenu, press Center (confirm). Always confirm your setting by pressing Center (confirm) for

2 seconds. Sto will appear to indicate saved settings.

Temperature shown in display

By default, the temperature shown on the display is the setpoint. This may be altered with parameter 13: ““Temperature display””. You may calibrate the sensor values “±4 degrees using parameters 10 to 12.

Standby and main screen

When the thermostat remains untouched for a while, it will automatically revert to the standby screen. The standby screen will by default show the setpoint temperature. By pressing any button once, you will see the measured temperature. By pressing the left or right (up or down) button one more time, you will change the setpoint.

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.

Association Groups:

Group NumberMaximum NodesDescription

relay
3| 5| Send Multilevel Sensor Reports for internal temperature sensor
4| 5| Send Multilevel Sensor Reports for external room temperature sensor
5| 5| Send Multilevel Sensor Reports for floor sensor

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.
