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.

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 Heatit Z-Relay is a Z-Wave module housed in a water-resistant casing with 10 membrane cable entries.
• It features 1 relay output, 3 multi-purpose inputs, and a Z-Wave radio for wireless network interfacing.
• The module requires a 230V AC mains power supply.
• The relay output can be freely controlled via the Z-Wave network, suitable for controlling devices like valve actuators and stoves.
• Two inputs can be configured as digital or analog for NTC temperature sensors, while the third can function as a digital input or connect to a flood sensor.
• The module allows configuration of the status indicator LED on its circuit board.

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 Heatit Z-Relay can be factory reset by pressing the inclusion button in the module for at least 10 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

• Only authorized technicians should perform work involving 230V mains power, adhering to country-specific guidelines and norms.
• Before assembly, ensure the power supply is switched off and safeguarded against reactivation.

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.

Product Usage

Temperature inputs
Input 1 and 2 can be used as temperature inputs by connecting NTC sensors to the inputs. The type of NTC sensor can be configured by means of configuration parameters 3 and 4.A temperature offset can be configured for each of the inputs by means of configuration parameters 5 and 6.

Flood sensor input
Input 3 is a flood sensor input where it is possible to connect a simple flood sensor. The flood sensor can be left lying on the floor (on an electrically insulating surface), or attached to the floor or a wall. Designed for flood detection, it senses water and other electrically conductive liquids. The sensitivity of the sensor can be configured by means of configuration parameter 14.
It is possible for the flood input to directly control the Heatit Z-Relay output, either to turn the relay output ON or OFF when a flood is detected, or when no flood is detected, see configuration parameters 12 and 13.

Relay Output
The relay output is a high power “normally open” (NO) contact that can be used for several purposes. It is possible to control the relay from the Z-Wave network, or it can be controlled by the flood sensor input.
The Heatit Z-Relay monitors the current used by the load connected to the relay output. The energy that the load consumes is calculated by means of the measured current and the voltage entered in configuration parameter 15. Energy data is sent to the controller through the Z-Wave network. These data values that the controller is able to receive are: current (A), power (Watt), and the energy consumed over time (kWh).

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.
