Firmware 1.1

1. 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.

2. STATEMENT REGARDING PRODUCT
FROM MULTIPLE MANUFACTURERS

Please read this before installation

This device may be used with all devices certied with the Z-Wave

Plus™ certicate and should be compatible with such devices

produced by other manufacturers. Every primary controller is dierent

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

certied device to ensure that it provides the necessary controls

to take full advantage of our product’s capabilities.

3. BEHAVIOR WITHIN THE Z-WAVE NETWORK

This product can be operated in any Z-Wave network with other

Z-Wave certied devices from other manufacturers. All non-battery-

operated nodes within the network will act as repeaters regardless

of manufacturer to increase 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 process 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.

4. QUICK START

1. Install the batteries (as stated in the technical specication).

2. Install the device on a at 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.

5. INSTALLATION

Use a large athead screwdriver to remove the back cover.

Fix the unit to the wall by double-sided tape, screws or installed

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 to when installing batteries, ensuring the polarity of

the batteries is in accordance with the printing in plastic.

7. 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.

8. COMPABILITY / PRINCIPLES FOR REGULATION8. COMPABILITY / PRINCIPLES FOR REGULATION

Water based heating

The thermostat uses temperature readings retrieved from the internal

sensor. Heatit Z-Temp2 is designed to work together with water based

heating solutions. Heatit 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 which 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.

6. ADD/REMOVE

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

6.1 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.

6. 2 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 back of the device, then follow the gateway instructions.

If the device already belongs to a network, follow the removing

process before adding it in your network. Otherwise, the adding of

this device will fail. When the device is removed from the network,

the device will revert to factory settings.

Electrical heating

Heatit 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.

9. INFORMATION SHOWN IN DISPLAY

The thermostat benets 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 display is active.

The temperature and humidity can be calibrated using parameter

4 and 5 respectively. When childlock is active, there will displayed

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 center button for 10 seconds, or use 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.

10. 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.

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.

11. CHILD LOCK - LOC

By pressing 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 Left and Right (down and up)

buttons for 10 seconds, the thermostat will display oPn. The lock

symbol is no longer lit when the display is active, and now you can

make changes using buttons.

12. 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 o. The proximity sensor

will activate the thermostat when proximity is sensed. You can also

activate the thermostat manually by pressing any button.

13. 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.

14. 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

conrm 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 conrmed

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 specic 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.
