Heat it 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 to Home Automation systems. Heat it Z-TRM3 is equipped with a single-pole relay and fits into System 55 frames. The thermostat can withstand a load of max 16A /3600W at 230VAC.
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.
Please read this before the 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 any manufacturer. Every primary controller is different depending on the manufacturer, their target audience, and their 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.
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 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 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.
Installation must be done by a qualified electrician in accordance with the National Building Code. Before installation, disconnect the power to the device from the mains. During the installation of the device, power to the device must be disconnected AT ALL TIMES!
Use e.g. a small slotted screwdriver. Start by carefully removing the front cover by pushing the release springs. The front cover and the frame may now be removed.
Connect the wires to the thermostat terminals. Use 1.5mm² or 2.5mm² according to load.
NB! Max tightening torque for terminal screws: 2Nm
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.
Please read this before the 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.
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 the 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”.
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.
The Z-Wave QR-Code locations may be found in Chapter 20 ”Z-Wave QR-Code/DSK”.
By pressing buttons Right and Center (down and confirm) for 20 seconds, the thermostat will perform a complete factory reset. The device will display rES for 10 seconds while performing a factory reset. When rES no longer is displayed, the thermostat has been reset.
NB! Please use this procedure only when the primary controller/ gateway is missing or otherwise inoperable.
Startup
After powering up the device for the first time, all the parameters will have default settings.
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 90 minutes and OFF for 30 minutes.
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.
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.
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.

Sensors:
The thermostat has a range of choices when it comes to sensors.
To access the menu, press Center (confirm) for 10 seconds, then press Right (down) once. An A will appear on the display. Then press Center (confirm) again and choose modes while moving up and down with buttons Left or Right:
When you have chosen sensor mode, press the Center (confirm) button. If you choose F without having a floor sensor connected, Er4 will be shown in the display. If you choose A2 or A2F and there is no external sensor installed, Er5 will be displayed on the screen.
NOTE: Wooden floors require that a floor sensor is connected in order to limit the floor temperature to a maximum of 27°C (in accordance with specifications from most wooden floor manufacturers).
When using the thermostat is used in (AF or A2F) the floor limiter FHI is automatically set to 27°C. When using any other sensor type (A, F, or A2F) the max temperatures are default 5°C minimum and 40°C maximum.
FLOOR SENSOR
The following values are available: NTC type (10, 12, 15, 22, 33, or 47kΩ). Default 10kΩ. Confirm with the Center (confirm) button. You can not combine two types of NTC sensors.
CAr, CAF, CAE – Parameters 10, 11, 12)
Using Floor / External sensor (F, A2, or A2F-mode)
In this mode, you may adjust the displayed temperature. If the Temperature sensor is not calibrated properly, you can make minor changes to the temperature readout. You can calibrate the measured temperature by up to ±6°C.
You may later adjust the temperature recorded by the sensor using the menu structure or using parameters.
| SENSOR TYPE | CALIBRATION FROM MENU STRUCTURE | PARAMETER |
| Internal sensor | CAr | 10 |
| Floor sensor | CAF | 11 |
| External sensor | CAE | 12 |
Use the Left and Right (up and down) buttons to adjust the brightness level from 0 to 9. Confirm with the Center (confirm) button.
In this mode, you can make changes to the thermostat hysteresis. You may change the hysteresis from 0.3°C up to a max of 3.0°C. Confirm with the Center (confirm) button. The Default setting is 0.5°C. When using water-based heating, the recommended hysteresis is a minimum of 1.0°C. This only applies when using a floor sensor or an external sensor.
This is a list of some functions that you may use without entering the menu structure. From the standby modus you may do the following:
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:
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.
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.
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.
