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-Water2 is a DIN-rail regulator for controlling waterbased heating systems. The module clips right onto a DIN-rail and allows you to control your waterbased heating through your Z-Waveâ„¢ network.
Heatit Z-Water2 is equipped with 9 potential free relays for actuators. It also has 2 analog inputs for temperature sensors.

The Heatit Z-Water2 relays may be controlled by associations with other Z-Wave thermostats e.g Heatit. Each relay can control one or several actuators in your underfloor heating system.

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.

Press and hold the reset button. After 3 seconds the LED will start to blink green. After 20 seconds the LED will start blinking green rapidly. You may now release the button. If reset was successful the LED will light solid green for 3 seconds.

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.

Installation

Installation must be done by a qualified electrician in accordance with national building codes. Before installation, disconnect the power to the device from the mains. During installation of the device, power to the device must be disconnected AT ALL TIMES!Max tightening torque for terminal screws: 2NmUse the following procedure to install Heatit Z-Water2:

1. Place the top part of the DIN rail mounting on the Heatit Z-Water2 over the top of the DIN rail so it hooks onto the rail.
2. Use a flathead screwdriver to push the DIN rail mounting tab downward.
3. Tilt the bottom of the Heatit Z-Water2 until it touches the DIN rail. Now let go of the DIN rail mounting tab so it locks into place.
4. Make all the necessary connections to the device (max tightening torque for all screw terminals is 2Nm). Apply power to the device after all connections have been made.

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

To start the configuration process, press the reset button 3 times in rapid succession. The LED will light solid green for 3 seconds if add is successful.

Exclusion

To start the configuration process, press the reset button 3 times in rapid succession. The LED will light solid green for 3 seconds if remove is successful.

Product Usage

CALIBRATION

• Parameters 1 and 2 allow you to calibrate the temperature displayed in the controller/gateway. If the temperature sensor readout is not correct, you can make minor changes to the temperature readout. You can calibrate the measured temperature by “±6″°C degrees.

External antenna (U.FL female connector)

• The device allows you to connect a U.FL female connector antenna. This allows the antenna to be wired outside the installation location in cases of unsatisfactory wireless performance. This connector is placed in the middle of the radio module that is sticking out of the main PCB. See Chapter 22 for a detailed illustration of the placement. Set parameter 8 to 1 to activate this feature.

EXTERNAL ANTENNA CONNECTOR

Automatic valve exercise

• Valve exercising is beneficial during longer periods of inactivity to ensure the proper operability of the valves and prevent the valves from getting stuck. If not exercised, corrosion or other buildup may result in the valve becoming inoperable or prevent complete closure. To activate this feature see Parameter 7.

LED BLINKING PATTERNS DESCRIPTION

• The device supports numerous LED blinking patterns to make it as easy as possible to identify what the device is doing.

Device Not in Network

• The LED will blink red when the device is not added to a Z-Wave network.

Add/Remove

• When device enters add/remove mode the LED will blink green. If successful, the LED will light up in solid green for 3 seconds. If unsuccessful, the LED will light up in solid red for 3 seconds.

Factory Reset

• success Within the 3 second period the button must be released. If the button is released within this period, the device will indicate that it has been successfully reset by lighting up in solid GREEN for 3 seconds. Then the device will start blinking RED because it is not included in a gateway.
• fail If the button is released before the 3 seconds period, the device will indicate fail by turning RED LED on for 3 seconds.
• fail The button MUST be released between 20 and 23 seconds for local reset to take place. If held longer, the device will ignore the command.

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:

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.
