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

Heatit Z-Temp2 is a battery-operated thermostat designed for usewith water based heating systems. Used in combination with theHeatit Z-Water regulator you can control your heating system with aZ-Wave primary controller/gateway with the use of Heatit Z-Water incombination with one or several Heatit Z-Temp2.

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 and holding the link button for 20 seconds, the thermostat will perform a complete factory reset. rES will be displayed.

Installation

Use a large flathead screwdriver to remove the back cover.” Fix the unit to the wall by double-sided tape, screws or installed” on top of a Euro wall box.”

Make sure the mounting surface is clean and dry.”

Then install 3x AA batteries (alkaline) in the device”’s battery-holder.

Note: Be careful to when installing batteries, ensuring the polarity of” the batteries is in accordance with the printing in plastic.

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

Press the link button on the thermostat 3 times in a rapid sequence

Exclusion

Press the link button on the thermostat 3 times in a rapid sequence

Product Usage

Z-Wave Button

Water based heating

The thermostat uses temperature readings retrieved from the internal sensor. Heatit Z-Temp2 is designed to work together with water based heating solutions. Heatit recommends using Heatit Z-Temp2 together with Heatit Z-Water. These two products allow for an advanced water based heating solution by using a Z-Wave enabled controller. This is a “wire-free” solution which save both time and money. All the communication between Heatit Z-Temp2 and the controlled device is wireless. The range can be extended using Heatit Z-Repeater or any other device that supports routing. This makes our water based solutions a good addition to your existing or new home automation system.

Electrical heating

Heatit Z-Temp2 could also be used in situations where a traditional electrical thermostat is not suited. The battery-operated thermostat can be used together with Heatit Z-Relay or any other relay device installed in a remote location. Rehabilitation could be done using this solution to avoid unnecessary wiring.

Display

The main screen

The main screen displays measured temperature readout or relative humidity. You can switch between the humidity and measured temperature by pressing the center button while display is active.

The temperature and humidity can be calibrated using parameter 4 and 5 respectively. When childlock is active, there will displayed” a lock icon adjacent to the Celsius icon.

Secondary screen

This screen displays the setpoint temperature when the thermostat is in heating mode. When the thermostat mode is turned OFF, the thermostat will not use this display. To turn ON or OFF the thermostat you need to hold center button for 20 seconds, or use Z-Wave command Basic or Thermostat mode.

Connecting to an external relay

After the device is added to your Z-Wave gateway you will need to link the thermostat to the device that is going to control the heating. This is done by using association groups from the thermostat”’s root device (EP0) with Group 3 (ON/OFF Control) towards your actuator device (using Multichannel or Single channel, based on the controlled device type.

Hysteresis (DIF)

You can make changes to the hysteresis in the thermostat via the parameter. This means that you can changes the hysteresis from” 0,3″°C up to max 3,0″°C. Default is 0,5″°C.

Child Lock – LOC

By pressing Left and Right (down and up buttons for 10 seconds,” the thermostat will display LOC. Child lock is now activated, and the lock icon will be lit up when the display is active. Trying to make changes from the display is not possible within this modus. Changes with the Z-Wave controller is still possible. Refer to your primary controller/gateways user manual on how to change the setpoint.”
Child lock is deactivated by pressing Left and Right (down and up)” buttons for 10 seconds, the thermostat will display oPn. The lock symbol is no longer lit when the display is active, and now you can make changes using buttons.

Standby and Main Screen

When the thermostat remains untouched for a while, it will automatically go to standby screen. Due to power saving settings, while in standby, the display will be turned off. The proximity sensor will activate the thermostat when proximity is sensed. You can also activate the thermostat manually by pressing any button.

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:

Press the link button on the thermostat 3 times in a rapid sequence

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 NumberMaximum NodesDescription

1	5	Lifeline. Normally used by the Z-WaveController.
2	5	Multilevel Sensor Report (internal measured temperate and measured

relative humidity).
3| 5| Binary Switch Set (normally used to control external relays).

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 200â€ˆit may be needed to set a value of 200 minus 256 = minus 56.
