Firmware 4.0

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 5 5 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 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.

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 in chapter 5 “Installation”.
4. After verifying the connections, switch the mains supply back on.
5. Set the primary controller in add mode (security/non-security).

7.1 STARTUP
AFTER POWERING UPT HETHERMOSTATFORTHE FIRSTTIME,ALL PARAMETERS WIL L HAVE DEFAULT SETTINGS.

8. PRINCIPLES OF REGULATION

Using Floor I 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 S “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 90 minutes and OFF for 30 minutes.

9. PROGRAMMING THE THERMOSTAT

To activate the programming mode, press Center (confirm) for 10 seconds. The display will show OFF. You are now in programming mode. 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·WAVEQR·CODE / DSK

The QR-Code is needed when including a device using 52 security or SmartStart. The Z-Wave OSK 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 underneath the front.
3. On the PCB internally.

21. SECURITY

52 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 52 and has a Z-Wave OSK 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 al lows 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 encapsulat on), 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.

ASSOCIATION GROUPS WITH MULTICHANNEL SUPPORT
When used in a system with Multichannel support:

ASSOCIATION GROUPS WITHOUT MULTICHANNEL SUPPORT
When used in a system without Multi Channel support:
