1. INTRODUCTION Heatit Z-TRM3 is an electronic thermostat for electrical floor heating, designed to be mounted in a standard flush box. The thermostat has a built-in Z-Wave chip that can be connected with Home Automation systems. Heatit Z-TRM3 is equipped with a single-pole switch and fits into System 55 frames. The thermostat can withstand a load of max 16A /3600W at 230V. The thermostat may be used for water based heating if the thermostat is linked to the Heatit Z-Water.NB! If the sensor mode is changed to A or AF mode then a room sensor compensation process will start, which limits maximum power output to 75%. The thermostat adapts to the environment within a few days. No internal sensor calibration should be performed during the first few days.2. STATEMENT REGARDING PRODUCTS FROM MULTIPLE MANUFACTURERSPlease 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 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.3. 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 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.The primary controller 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.4. QUICK START 1. Switch off the mains supply (disable the fuse). 2. Open the wall switch box. 3. Connect wires according to the labeling described inchapter 5 “Installation”. 4. After verifying the connections, switch the mains supply back on. 5. Set the primary controller in add mode (security/non-security). 6. Press and hold the center button until “OFF” is shown on thedisplay (approx. 10 seconds). 7. Press down button until you reach “CON”, press and hold until thedisplay shows a rotating light pattern. 8. The thermostat will display “INC” when the thermostat issuccessfully added. NB! If adding/removing fails, Err (error) will appear.

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

Next, position the thermostat and mount it into the wall flush box using 2-4 screws. Position the frame over the flush box, then position and carefully press the front cover until it snaps in place. Check that the front cover has snapped in place properly on both sides. The front

cover should now fit firmly on all sides. In order to read the Power Metering, the load needs to be connected to both heating L + N.NOTE! The top cover has to be installed when the thermostat is connected to the main power source. The thermostat is not a SELV product. All voltage parts must be considered to be 230VAC.6. ADD/REMOVE 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 Heatit Z-TRM3 to a Z-Wave network.6.1 METHOD 1: STANDARD (MANUAL) 1. Press Center (confirm) for 10 seconds. The display will show OFF. 2. Press Right (down) 5 times until you see Con on the display. 3. Start the add/remove device process in your primary controller. 4. Start the add/remove mode in the Heatit Z-TRM3 by pressingCenter (confirm) for approximately 2 seconds.Adding/removing mode is indicated on the display by rotating LED segments on the display. This lasts until the timeout occurs after 90 seconds, or until the module has been added/removed in the network. Confirmation will show Inc/EcL on the display. Exit programming mode by choosing ESC in the menu. Your thermostat is now ready for use with default settings. NB! When the thermostat is removed from the gateway, the parameters are not reset. To reset the parameters, see Chapter 7: “Factory reset”. If adding/removing fails, Err (error) will appear. Please perform a “remove device”process and try again. If Err displays again, please see Chapter 7: “Factory reset”.6.2 METHOD 2: SMARTSTART (AUTOMATIC) 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. The Z-Wave QR-Code locations may be found in Chapter 20 “Z-Wave QR-Code/DSK”.7. FACTORY RESET By pressing buttons Right and Center (down and confirm) for 20 seconds, the thermostat will perform a complete factory reset. NB! Please use this procedure only when the primary controller/ gateway is missing or otherwise inoperable. The device will display rES for 10 seconds while performing a factory reset. When rES no longer is displayed, the thermostat has been reset.7.1 STARTUP AFTER POWERING UP THE THERMOSTAT FOR THE FIRST TIME, ALL PARAMETERS WILL HAVE DEFAULT SETTINGS.

8. PRINCIPLES OF REGULATION Using Floor / External sensor (F, A2 or A2F-Mode) The thermostat uses temperature readings retrieved from the internal sensor or external wired sensor to regulate heating. When you have chosen a setpoint temperature, the thermostat will use an internal hysteresis to regulate the temperature. This hysteresis is adjustable. See Chapter 5 “Installation”.

Using Internal sensor (A-mode/AF mode) If you have a set point of 20°C, the thermostat will use the full power until the temperature is 19°C. The thermostat will then begin to regulate the output from 19°C with a 75% duty cycle until it reaches 19,25°C. When the temperature has reached 19.5°C the thermostat will use a 50% duty cycle, until it reaches 20°C, then the thermostat turns off and repeats the process. For example, at a 75% duty cycle it will turn ON for a total of 90minutes and OFF for 30 minutes.

To scroll up and down in the menu, use buttons 1 and 3 (left and right) to navigate. To enter the submenu, press Center (confirm). Always confirm your setting by pressing Center (confirm) for 2 seconds. Sto will appear to indicate saved settings.10. TEMPERATURE SHOWN IN DISPLAY By default, the temperature shown on the display is the setpoint. This may be altered with parameter 13: “Temperature display”. You may calibrate the sensor values ±4 degrees using parameters 10 to 12.11. STANDBY AND MAIN SCREEN When the thermostat remains untouched for a while, it will automatically revert to the standby screen. The standby screen will by default show the setpoint temperature. By pressing any button once, you will see the measured temperature. By pressing the left or right (up or down) button one more time, you will change the setpoint.

20. Z-WAVE QR-CODE / DSK The QR-Code is needed when including a device using S2 security or SmartStart. The Z-Wave DSK can be found in the QR-Code which is located in 3 locations; 1. On the product box. 2. On the physical product, placed on the black plastic underneaththe front. 3. On the PCB internally.

21. 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.

22. 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.

23. 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.

MULTICHANNEL SUPPORT Heatit Z-TRM3 has support for the Multichannel Command Class. This allows the thermostat to be perceived as many devices by the primary controller, where each of the devices has association groups in order to send information to other Z-Wave devices. See the chapter concerning “Association Groups” for more information. Commands sent to each logical device will be interpreted according to the description in the section “Supporting Command Classes”.

NO MULTICHANNEL SUPPORT If the primary controller or the Z-Wave devices to be associated with Heatit Z-TRM3 do not support the Multichannel Command Class (Multichannel encapsulation), only the association groups in the root device are accessible. This device contains 5 association groups. See Chapter 23 concerning “Association Groups” for more information. The root device is the actual thermostat device.
