INTRODUCTION

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

STATEMENT REGARDING PRODUCT 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 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.

BEHAVIOR WITHIN THE Z-WAVE NETWORK

This product can be operated in any Z-Wave network with other 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 devices of this network. Devices can also be removed from a network. Both adding and removing processes are initiated by the primary controller of the Z-Wave network.
This controller will enter a mode for adding or removing devices. Please refer to your primary controller/gateway manual on how to turn your controller into add or remove mode. The device can 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, the device will revert to factory default settings.

QUICKSTART

1. Install the batteries (as stated in the technical specification).
2. Install the device on a flat vertical surface using screws or double-sided tape
3. Set the controller/gateway in add mode (security/non-security).
4. Press the link button 3 times in a rapid sequence.
5. The thermostat will display “INC” when the thermostat is successfully included.
   NB! If adding/removing fails, Err (error) will appear.

INSTALLATION

Use a large flathead screwdriver to remove the back cover.
Fix the unit to the wall with double-sided tape, screws, or installed it 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.
NB! Be careful when installing batteries, ensuring the polarity of the batteries is in accordance with the printing in plastic.

ADD/REMOVE

There are two ways to add your devices in a Z-Wave network.

METHOD 1: STANDARD (MANUAL)

Please refer to your primary controller/gateway manual on how to enter add/remove mode. The device can only be added or removed from the network if the primary controller is in add/remove mode. When the primary controller/gateway is set to add/remove mode press the link button on the thermostat 3 times in a rapid sequence.

METHOD 2: SMARTSTART (AUTOMATIC)

Please refer to your primary controller/gateway to see if SmartStart is supported by the controller. SmartStart enabled products can be added into a Z-Wave network by scanning the Z-Wave QR-Code present on the product with a controller providing SmartStart inclusion. No further action is required and the SmartStart product will be added automatically within 10 minutes of being switched on in the network vicinity. Enter SmartStart modus from your primary controller. With the batteries for the devices taken out of the device. Scan the QR-code on the back of the device, then follow the gateway instructions. If the device already belongs to a network, follow the removing process before adding it to your network. Otherwise, the addition of this device will fail. When the device is removed from the network, the device will revert to factory settings.

FACTORY RESET

By pressing and holding the link button for 20 seconds, the thermostat will perform a complete factory reset. rES will be displayed.
NB!  Please use this procedure only when the primary controller/ gateway is missing or otherwise inoperable.

COMPATIBILITY / PRINCIPLES FOR REGULATION

Water-based heating
The thermostat uses temperature readings retrieved from the internal sensor. Heat Z-Temp2 is designed to work together with water-based heating solutions. Heat 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 that 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
Heat 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.

INFORMATION SHOWN IN DISPLAY

The thermostat benefits from two screens.
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 the display is active. The temperature and humidity can be calibrated using parameters 4 and 5  respectively. When child lock is active, there will display 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 the center button for 20 seconds or use the 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.
*To set associations in your primary controller/gateway, please refer to your primary controller/Z-Wave gateway for more information.

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 the 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 the Left and Right (down and up) buttons for 10 seconds, the thermostat will display in. 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.

Z-WAVE QR-CODE / DSK

The QR Code is needed when including using S2-Security or SmartStart. The Z-Wave DSK can be found in the QR-Code and is located;
1. On the back of wall mount (above the battery compartment).
2. Inside the packaging attached on the note.
3. On the product packaging.

SECURITY

The 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. The Heatit Z-Temp2 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.
