INTRODUCTION

Heat it Z-TRM6 is an electronic thermostat designed for electrical heating. The thermostat can be controlled through your Z-Wave™ network or via the buttons on the front. The thermostat has a user friendly interface.
Heat it Z-TRM6 has 3 modes; Heat – Cool and Eco.
The thermostat fits in standard European junction boxes and may be used with most System 55 frames. It has a sturdy metal frame for secure fastening on the junction box. The thermostat has one built-in room temperature sensor. Two additional external temperature sensors may also be connected.
Heat it Z-TRM6 has active power metering and it gives you real time information about your power consumption. It also allows you to set the power metering value manually in case of connection with a contactor.
The thermostat can be set up with multiple associations and can be used as a master thermostat. It can also control external relays and wall plugs.
The thermostat can withstand a load of max 16A/3600W at 230VAC. We recommend a contactor for loads above 13A.

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 any manufacturer. Every primary controller is different 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 certified device to ensure that it provides the necessary controls to take full  advantage of our product’s capabilities.

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.

QUICK START

1. Switch off the mains voltage (disable the fuse).
2. Open the junction box.
3. Connect the wires according to the description in Chapter 6; ”Connections”. Optional: Connect external wired sensors.

Position the thermostat front over the part mounted in the junction box, then carefully press the front until it clicks into place. In order to get power  metering values, the load needs to be connected to both heating L + N.

ADD/REMOVE

Please read this before 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.
An always listening node must be powered continuously and reside in a fixed position in the installation to secure the routing table. Adding the device within a 2 meter range from the gateway can minimize faults during the Interview  process.
There are two ways to add the device to a Z-Wave network.

7.1 Method 1: Standard (Manual)
Add/remove mode is indicated on the device by rotating LED segments on the display. It indicates this for 90 seconds until a timeout occurs, or until the device has been added to/ removed from the network. Configuration mode can also  be cancelled by performing the same procedure used for starting Configuration mode.

1. Hold the Center button for 5 seconds.
   The display will show “OFF”.

2. Press the ”+” button once to see “CON” in the display.

3. Start the add/remove device process in your primary controller.

4. Start the configuration mode on the thermostat by holding the Center button for approximately 2 seconds.

The device is now ready for use with default settings.
NB! When the device is removed from the gateway, the parameters are not reset. To reset the parameters, see Chapter ”Factory reset”.
If inclusion fails, please perform a ”remove device” process and try again. If inclusion fails again, please see “Factory reset”.

7.2 Method 2: SmartStart (Automatic)
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.

FACTORY RESET

Enter the menu by holding the Center button for about 5 seconds, navigate in the menu with the ”+” button til you see FACT. Press the Center button until you see “– –” blinking in the display, then hold for about 5 seconds to perform a  reset. You may also initiate a reset by holding the Right and Center buttons for 60 seconds.
When either of these procedures has been performed, the thermostat will perform a complete factory reset. The device will display “RES” for 5 seconds while performing a factory reset. When “RES” is no longer displayed, the thermostat  has been reset.
Please use this procedure only when the network primary controller is missing or otherwise inoperable.

STARTUP

After powering up the device for the first time, all parameters will have default settings and the thermostat will start by asking which sensor mode should be used.

PRINCIPLES OF REGULATION

The thermostat uses temperature readings retrieved from the internal sensor and/or from external wired sensors to regulate the temperature. The thermostat will regulate the temperature using hysteresis or PWM, based on the setpoint temperature. To select either “HYST” or “PWM” you can find the “REG” menu option or use Parameter 13 “Regulation mode (“OPER”)”.
10.1 Hysteresis
Hysteresis will turn on and off the load based on the hysteresis value in comparison to the setpoint. You can make changes to the thermostat hysteresis. You may choose hysteresis values between 0.3°C and 3.0°C using Parameter 14. The
default setting is 0.5°C. When using waterbuses heating we recommend a hysteresis of 1.0°C.
You may also change the hysteresis by entering the local settings menu and holding the Center button for 2 seconds when “REG” is displayed. Here you can choose values between 0.3 and 3.0.
10.2 Pulse-width modulation PWM
With PWM regulation enabled, the thermostat will regulate based on duty cycles. The thermostat is turned on and off in percentage intervals of the cycle. The amount of time the relay will be on is based on how far the measured  temperature is from the setpoint.

LOCAL SETTINGS MENU

To enter the settings menu, hold the Center button for 5 seconds. The display will display “OFF”. You are now in the settings menu. While in the settings menu, “SET” will be displayed in the bottom right of the display. You can now scroll up and down using the Left and Right buttons. Some options have submenus. To navigate the submenus, press the Center button once to enter or exit the submenu. Press the Left and Right buttons to find your desired value and hold the  Center button for 2 seconds to confirm your selection. “STOR” will appear to indicate settings are stored.

DISPLAY MENU STRUCTURE

See flowchart at the end of this manual.

TEMPERATURE SHOWN IN DISPLAY

By default, the temperature shown on the display while in standby state is the setpoint. This may be altered with Parameter 15:”Temperature display”. It may also be changed by entering the local settings menu and holding the Center button for 2 seconds when “MODE” is displayed. You can choose between “SETT” and “RELT”. “SETT” is the Setpoint temperature and “RELT” is the real-time temperature.

STANDBY AND MAIN SCREEN

When the thermostat remains untouched for a while, it will automatically go to the standby screen. The standby will by default show the setpoint temperature.
By pressing any button once, you will see the measured temperature. By pressing the Left or Right button multiple times, you will change the setpoint.

KWH VALUE IN MENU

The device supports power metering to give insight into the power consumption of the heating. The total consumption of the device can be seen in the system from the “kWh” menu option. The total consumption data can be reset by holding the Center button while in the kWh menu.

SIZE OF LOAD

In the “load” menu or from Parameter 29 (size of load), the load value can be set manually if the load is not directly connected to the thermostat. The size of load can be adjusted in 100W increments up to 9900W.

 CHOICE OF SENSOR

The thermostat has multiple sensors and sensor modes. This lets you configure the thermostat to work correctly in most installations. The sensors and modes may be selected from either the local settings menu or via Parameter 2; ”Sensor mode (“OPER”)”.
Available sensor modes:

NOTE: Some types of floor require that a floor sensor is connected in order to limit the floor temperature to a maximum of 27°C (check the manual from the floor manufacturer). When 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 A2) the minimum and maximum limits are 5°C and 40°C respectively.

SELECTING SENSOR VALUE

The thermostat allows the selection of multiple different resistance values of an NTC sensor and can be selected using either the local settings menu or via Parameter 3: ”Sensor value “SEN”. The supported sensor values are as follows:
6.8, 10, 12, 15, 22, 33, 47 or 100KΩ.
The factory default value is 10kΩ. When connecting both the floor sensor and the external sensor, make sure to use sensors with the same Ohm value.

CALIBRATION

If the temperature sensor readout is not correct, you can make  minor changes to the temperature readout. The temperature readings can be calibrated by ±6°C using Parameter 10, 11 and 12. The calibration can also be performed from  the menu using CAR, CAE and CAF. The adjusted value will be displayed in the controller/gateway indicating what the thermostat uses for regulation.

BRIGHTNESS

Using the menu choices “BR1” and “BR2”, the brightness of the display in Active and Standby state can be changed respectively. “BR1” and “BR2” are also included in the device as Parameter 16 (BR1) and Parameter 17 (BR2).

DISPLAY ON/OFF (DON/DOFF)

The thermostat has a display ON/OFF function which decides whether the display should turn completely off when in Standby. To enable/disable this function, hold the Left and Center buttons for 10 seconds. The display will show  “DOFF” when the function is activated and “DON” when the function is disabled. When operating any button, the display will light up.

DISPLAY ICONS

CHILD LOCK
Child lock is a function for disabling the buttons from the display locally. It will show “LOCK” when attempting to operate it while the function is enabled. To enable or disable the function, hold the Left and Right buttons for 10 seconds. Enabling the function will show “LOCK” in the display, disabling the function will show “OPEN”.

OPEN WINDOW DETECTION OWD

Open Window Detection (OWD) is a function which will reduce the thermostat setpoint on detection of an open window. This happens when the temperature sensor registers a rapid temperature drop.
When OWD is active, the setpoint is reduced to 5°C in order not to waste energy. OWD will automatically be cancelled if OWD has been active for more than 1 hour, or if the temperature increases by 3°C. OWD can also be cancelled manually by increasing/decreasing the setpoint with the Left and Right buttons.
By default, OWD is not enabled. The feature may be enabled by selecting “OWD” from the menu. Choose between options “OFF” and “ON”.

SAFETY FEATURES

The device has safety features to ensure safe operation and warn the user of any faults/unexpected behavior. The device has an Overheat and Overload function. If the thermostat registers an Overheat or Overload incident, the thermostat  will switch off and an error will appear in the display.

26.1 Overheating
The device features internal temperature sensors that  detect overheating. It warns the user and turns off the relay to prevent any damage.
When overheating is detected, the device will:

• Turn off the relay.
• Display Err6 in the display.
• Send a notification to the gateway.

26.2 Overload
The device features a 16A overload protection. The overload is triggered if there is a current draw of more than 16A.
When overload is detected, the device will:

• Turn off the relay.
• Display Err7 in the display.
• Send a notification to the gateway.

26.3 Sensor failure
The device has the ability to detect when there is no sensor connected or the sensor is broken or otherwise defective, causing an open circuit.
When the device detects the sensor error, the device will:

• Turn off the relay.
• Display an error in the display, changes based on which sensor is not connected/faulty.

To clear the “Sensor not connected” error the device has to be disconnected from the mains, and the wiring and sensor(s) need to be checked. When the fault is resolved the mains can be reconnected and the device will function normally again.

QR-CODE PLACEMENT (DSK)
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;

• On the product.
• In the Quick Guide.
• On the packaging box/gift box.

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 device is added to the Z-Wave home network. The primary controller will ask for a 5-digit code. They are the first underlined 5 digits located on the QR code sticker. The primary controller will then ask you to confirm the rest of the code that is contained in the QR-Code.

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.

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.

30.1 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.
30.2 Multi Channel support
Heat it Z-TRM6 has support for the Multi Channel Command Class. This allows the thermostat to be perceived as multiple devices by the primary controller, which enables the reporting of multiple temperature sensors and the ability to distinguish between the reports coming from the device.
30.3 No Multi Channel support
If the primary controller or the Z-Wave devices to be associated with Heat it Z-TRM6 do not support the Multi Channel Association Command Class (Multi Channel encapsulation), only the association groups in the root device are accessible. This device contains 3 association groups in addition to the Lifeline Group.
