1. INTRODUCTION Heatit Z-Dim2 is a Z-WaveTM rotary dimmer for many different types of light fixtures. The Heatit Z-Dim2 works on most low loads without causing flickering.
The dimmer is equipped with an external switch option. This allows you to dim and turn on/off the load from an external switch.
Heatit Z-Dim2 is very well suited for LED, and fits into System 55 frames. When connecting low loads it is recommended to use a bypass.
NB! DIMMING Dimming may be challenging, and we recommend checking the compatibility of different light sources before installation. We are happy to answer any questions.
2. STATEMENT REGARDING PRODUCTS FROM MULTIPLE MANUFACTURERS Please read this before installation This device may be used with all devices certified with the Z-Wave PlusTM certificate and should be compatible with such devices produced by any manufacturer. Every primary controller is different depending on the manufacturer, their target audience 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.
3. BEHAVIOUR WITHIN THE Z-WAVETM NETWORK This device may be operated within any Z-Wave network with Z-Wave-certified devices from other manufacturers. All non-batteryoperated nodes within the network will act as repeaters regardless of 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.
4. QUICK START 1. Switch off the mains voltage (turn off the fuse). 2. Open the junction box. 3. Connect according to the wiring diagram as shown in chapter 7
“Installation & wiring”. 4. After verifying the connections, switch on the mains voltage. 5. Set the primary controller in add mode (security/non- security). 6. Press the reset button on dimmer 3 times in a rapid sequence.
Heatit Z-Dim2 is now included in your Z-Wave network.

Wiring diagram

8. EXTERNAL SWITCH Momentary Switch (NO) When using a momentary switch, the switch functionality can be selected using Parameter 7. The switch must be a normally open switch.
9. 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.
9.1 Method 1: Standard (Manual) Add/remove mode is indicated on the device by a blinking green LED. It indicates this for 90 seconds until a timeout occurs, or until the module has been added to/removed from the network. To start the configuration process press the Reset button, or the external switch connected to P, 3 times in rapid succession. The LED will blink green for 3 seconds if adding/removing is successful. The device is now ready for use with default settings.
NB! When the device is removed from the gateway, the parameters are not reset. To reset the parameters, see Chapter 10 “Factory reset”.
If inclusion fails, please perform a “remove device” process and try again. If inclusion fails again, please see Chapter 10 “Factory reset”.
9.2 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.
10. FACTORY RESET Please read this before installation Press and hold the reset button. After 3 seconds the LED will start to blink in green. After 20 seconds the LED will shine solid green for 3 seconds. You may now release the button.
Please attempt exclusion before using factory reset.
11. STARTUP After powering up the device for the first time, all the parameters will have default settings.

12. 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.

13. 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; · On the product. · On the Quick Guide. · On the gift box.
14. SECURITY S2 security enhances Z-Wave Plus with an additional layer of AES 128-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.
15. 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.

16. 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.

16.1 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.

17. ASSOCIATION GROUPS
