INTRODUCTION

Heat ZM Single Relay is a high-power relay for in-wall installations. The relay allows you to control connected devices either through your Z-Wave network or via a wired switch. The module is equipped with a 16A relay and has scene controller functionality. The device can withstand a load of max 16A /3600W at 230VAC.

STATEMENT REGARDING PRODUCTS FROM MULTIPLE MANUFACTURERS
Please read this before installation
This device may be used with all devices certified with the Z-Wave Plus™ certificate and should be compatible with such devices produced by other manufacturers. Every primary controller is different depending on the manufacturer, their target consumer, and intended use/application. Please review the functionalities implemented by the primary controller you intend to use with our Z-Wave Plus certified device to ensure that it provides the necessary controls to take full advantage of our product’s capabilities.

BEHAVIOR WITHIN THE Z-WAVE™ NETWORK
This device may be operated within any Z-Wave network with Z-Wave-certified devices from other manufacturers. All non- battery-operated nodes within the network will act as repeaters regardless of the manufacturer to increase the reliability of the network. On delivery, the device does not belong to any Z-Wave network. The device needs to be added to an existing network to communicate with the other devices within it. Devices may also be removed from a network. The add/remove processes are initiated by the primary controller of the Z-Wave network.

QUICKSTART

1. Switch off the mains supply (disable the fuse).
2.  Open the wall switch box.
3.  Connect wires according to the labeling described in Chapter 5 ”Installation”.
4. After verifying the connections, switch the main supply back on.
5. Set the primary controller in add mode (security/non-security).
6. Press the configuration button or switch connected to S1 x 3 times in rapid succession.
7. The device LED will blink in green when adding procedure has been successfully initiated. When the device is included in the home automation system, the LED will light up in green for 1 second. If the device is unsuccessfully added, the LED will light up in RED for 1 second. For more information, please see Chapter 7 ”Add/ Remove”.
8. Change the value of Parameter 11 to 10% of your connected load.

INSTALLATION

Installation must be done by a qualified electrician in accordance with the National Building codes. Before installation,  disconnect any power to the device mains. During the installation of the device, power to the device must be disconnected AT  ALL TIMES!

O Output – Load needs to be connected between O and Neutral.
N Power connection (Neutral) 230VAC.

CONTROL
The device features a configuration button and an LED indicator.

ADD/REMOVE

Please read this before installation
The primary controller/gateway has a mode for adding or removing devices. Please refer to your primary controller manual on how to set the primary controller in add/remove mode. The device may only be added or removed from the network if the primary controller is in add/remove mode.
When the device is removed from the network, it will NOT revert to factory settings.
There are two ways to add the device to a Z-Wave network.

Method 1: Standard (Manual)
Add/remove mode is indicated on the device by a blinking green LED.
This lasts until a timeout occurs after 90 seconds, or until the module has been added to/removed from the network.
The LED will light up for 3 seconds if adding/removing is successful. The device is now ready for use with default settings.
If adding/removing fails, the LED will light up in red for 3 seconds.
NB! When the device is removed from the gateway, the parameters are not reset. To reset the parameters, see Chapter 8 ”Factory reset”.  If inclusion fails, please perform a ”remove device” process and try again. If the LED lights up in red again, please see chapter 8 “Factory reset”.

7.2 Method 2: SmartStart (Automatic)
SmartStart enabled products may be added to a Z-Wave network by scanning the Z-Wave QR-Code on the product if your primary controller supports SmartStart inclusion. No further action is required and the SmartStart product will be added automatically after being powered on within range of the primary controller.

FACTORY RESET

Press and hold the configuration button. After 3 seconds the LED will start to blink in green. After 20 seconds the LED will stop blinking and emit a constant light. You may now release the button.
NB! Please use this procedure only when the primary controller/ gateway is missing or otherwise inoperable.

STARTUP
After powering up the device for the first time, all the parameters will have default settings.

SAFETY FEATURES

The device security features make the device safe to use and notify the user of any unexpected behavior in the device, such as overload or overheating. If this happens, the relay cuts power to prevent failure.

Heat ZM Single Relay 16A has the following features: 10.1 Overload

The device features a default 16A overload protection. The default overload is triggered if there is a power draw of more  han16Amps for longer than 2 seconds, or 0.2 seconds if the measured load is more than 20A. When a current higher than  16Amps has been detected, the connected load must be checked. It is not possible to turn the relay back on until a power cycle has been performed. This prevents unwanted power cuts that may be caused by inrush currents. The user may define a specific user cut off according to the need using Parameter 1.

When an overload is detected, the device will:

• Set the relay in OFF-state when triggered and send a binary switch report representing relay state
• Send Notification (Overload detected)

To clear the overload state, the relay must be switched back on manually using Z-Wave or a connected switch. When the real state has been changed and overload is no longer triggered, the device will send a Notification (Overload idle). Parameter 2 can be set to automatically retry at regular intervals. This Parameter 2 setting will only work if the overload was triggered by a user-specific load limit (Parameter 1).

10.2 Overheating
The device features an internal temperature sensor that prevents any overheating caused by external high loads.

When overheating is detected, the device will:

• Set the relay in OFF-state when triggered and send a binary switch report representing relay state
• Send Notification (Overheating detected)

To clear the overheating state, the relay must be switched back on manually using Z-Wave or a connected switch. When the relay state has been changed and the temperature stabilized, the device will send a Notification (Overheating idle). Parameter 2 can be set to automatically retry at regular intervals.

SWITCH MODE

The device supports two types of switches, momentary and toggle switches. The device uses momentary switches by default.

11.1 Momentary Switch – Default
This is the recommended mode that allows for the use of all features. When used as a momentary switch, the device supports the  HOLD and RELEASE functions for central scene and association groups. The switch must be a normally open switch.

11.2 Toggle Switch (ON/OFF)
In toggle mode, the device relay and switch state will not always be equal as the user can control using other Z-Wave devices. When using the device in toggle switch mode, the device will lose the following functionality:

• Inclusion using S1
• Scene Controller Commands
• Association Group 3 and 5, Multilevel Switch (level increase/decrease)

The toggle switch will not always turn ON when the output of the switch is HIGH because the relay may also be controlled externally using the Z-Wave protocol.

NB! When using the toggle switch, S2 must not be connected in order to ensure correct functionality.

LED BLINKING PATTERNS DESCRIPTION

The device supports numerous LED blinking patterns to make it as easy as possible to identify the issue.

Device Not in Network

The LED will flash in red when the device is not added to a Z-Wave network

Device Status

On: Green for 1 sec
Off: Red for 1 sec
(when LED’s are enabled)

Add/Remove

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

Factory Reset
If the button is pressed for more than 3 seconds, the GREEN LED will start flashing.
When the button has been pressed for 20 seconds, the GREEN LED will light up for 3 seconds.

Figure 1

Figure 1 (success)
Within the 3 second period, the button must be released. If the button is released within this period, the device will reset and start flashing because it is not included in a gateway.

Figure 2 (fail)
If the button is released before the 3 second period, the device will indicate fail by turning RED LED on for 3 seconds.

Figure 3 (fail)
The button MUST be released between 20 and 23 seconds for the local reset to take place. If held longer, the device will ignore the command.

QR-CODE PLACEMENT (DSK)

The QR-Code is needed when including a device using S2 security or SmartStart. The DSK can be found in the QR-Code and is located;

1. On the product.
2. On the Quick Guide manual.
3. On the product box.
4.  SECURITY

S2 security
enhances Z-Wave Plus with an additional layer of AES128-bit encryption of the wireless Z-Wave communication to prevent hacking and man-in-middle attacks on the home network. This device supports S2 and has a Z-Wave DSK QR-Code label that may be used when the module is added to the Z-Wave home network. The primary controller will ask for a 5-digit code, which can be found underneath the QR-Code. The primary controller will then ask you to confirm the rest of the code that is contained in the QR-Code.

NODE INFORMATION FRAME
The node information frame is the ”business card” of a Z-Wave device. It contains information about the device type and its technical features. The add and remove procedure of the device is confirmed by sending out a node information frame. Besides this, it may be necessary for certain network operations to send out a node information frame.

ASSOCIATIONS
Z-Wave devices interact with other Z-Wave devices. The relationship between one device controlling another device is called an association. In order to control a subordinate device, the controlling device needs to maintain a list of devices that will receive controlling commands. These lists are called ”Association Groups”. They are always related to the specific event triggered (e.g.,   sensor reports). In case the event is triggered, all devices stored in the respective association group will receive a joint wireless command.

Setting and removing associations
Associations may be assigned and removed via Z-Wave commands. Please refer to your primary controller/Z-Wave gateway for more information.
