Z-TRM3  

Installers manual  

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 relay and fits  

into System 55 frames. The thermostat can withstand a load of max  

16A /3600W at 230VAC.  

Firmware 4.0  

01.01.2021  

Ver 2021-B (15.10.21)  

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 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.

Summary of Contents

• Page 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 relay and fits into System 55 frames. The thermostat can withstand a load of max 16A /3600W at 230VAC. Statement regarding products from multiple manufacturers 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. Please review the functionalities implemented by the primary controller you intend to use with our Z-Wave Plus certified device. 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. Quick Start Switch off the mains supply (disable the fuse). Open the wall switch box. Connect wires according to the labeling described in chapter 5 Installation. After verifying the connections, switch the mains supply back on. Set the primary controller in add mode (security/non-security). Error codes If adding/removing fails, Err (error) will appear.
• Page 2: Installation must be done by a qualified electrician in accordance with the National Building codes. Before installation, disconnect the power to the device from the mains. During installation of the device, power to the device must be disconnected at all times. The primary controller/gateway has a mode for adding or removing devices. The device may only be added or removed from the network if the primary controller is in add/remove mode. Adding/removing mode is indicated on the display by rotating LED segments on the display. When the thermostat is removed from the gateway, the parameters are not reset. SmartStart enabled products may be added to a Z-Wave network by scanning the Z-Wave QR-Code on the product. By pressing buttons Right and Center for 20 seconds, the thermostat will perform a complete factory reset. After powering up the device for the first time, all the parameters will have default settings.
• Page 3: The display brightness may be adjusted in this menu. Activation of inclusion/exclusion mode. The thermostat uses temperature readings retrieved from the internal sensor or external wired sensor to regulate heating. This hysteresis is adjustable. Setting lowest allowed temperature (limitation). Setting highest allowed temperature (limitation). The thermostat will use the full power until the temperature is 19°C. When you have chosen sensor mode, press the Center (confirm) button. To activate the programming mode, press Center (confirm) for 10 seconds. By default, the temperature shown on the display is the setpoint.
• Page 4: QR-Code placement is essential for including a device using S2 security or SmartStart. The DSK can be found on the product, Quick Guide manual, and product box. S2 security enhances Z-Wave Plus with AES 128-bit encryption to prevent hacking. The primary controller requires a 5-digit code found under the QR-Code for network addition. Hysteresis settings can be adjusted from 0.3°C to a maximum of 3.0°C, with a default of 0.5°C. Recommended hysteresis for water-based heating is a minimum of 1.0°C. The node information frame contains details about the device type and technical features. It is used for confirming the add and remove procedure of the device. Associations allow Z-Wave devices to interact, maintaining lists of devices that receive commands based on specific events. Fast functions from standby include display on/off and child lock features. The display can be activated temporarily by pressing buttons. Heatit Z-TRM3 supports the Multichannel Command Class, allowing it to be perceived as multiple devices by the primary controller. Error codes indicate various issues, such as adding failures or internal errors, and may require contacting a local dealer for resolution.
• Page 5: Association Groups Operation mode: Device turned on or off. Thermostat device 1: Heating mode. Sensor mode: Chooses which sensor type to use with thermostat. Multilevel sensor device 2: Device for internal room temperature sensor. Temp. Adjusts the hysteresis. Floor min. temp. limit: Chooses min. floor temperature before engaging thermostat. Air min. temp. limit: Chooses min. air temperature before engaging thermostat. Heating mode setpoint: Defines the thermostat setpoint. Configuration parameters: Selects which temperature is shown on the display. Z-Wave products are supposed to work out of the box after inclusion.
• Page 6: Heatit Z-TRM3 has support for various command classes beyond the mandatory ones. Brightness of the display can be configured from 0 to 100%, with a default of 50%. A Basic command can change the Thermostat Mode, with values for OFF and Heating Mode. The temperature report interval can be set between 30 to 32767 seconds, with a default of 60 seconds. The thermostat can send Binary Switch commands to control other devices. Temperature reports are sent based on a defined hysteresis, with a default of 10 (1.0°C). The operating mode of the thermostat can be changed using a Thermostat Mode Set command. The Meter report interval can also be set between 30 to 32767 seconds, with a default of 90 seconds. The thermostat reports its operating state using a specific command class, with values for Idle and Heating. The device supports both authenticated and unauthenticated security for Z-Wave communication.
