What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This
device is suited for use in the region mentioned in the Quickstart section.

Z-Wave ensures a reliable communication by reconfirming every message ( two- way
communication) and every mains powered node can act as a repeater for other nodes
( meshed network ) in case the receiver is not in direct wireless range of the
transmitter.

This device and every other certified Z-Wave device can be used together with any other
certified Z-Wave device regardless of brand and origin as long as both are suited for the
same frequency range.

If a device supports secure communication it will communicate with other devices
secure as long as this device provides the same or a higher level of security.
Otherwise it will automatically turn into a lower level of security to maintain
backward compatibility.

Product Description

Heatit Z-TRM6 is an electronic thermostat designed for electrical heating. The thermostat can be controlled through your Z-Waveâ„¢ network or via the buttons on the front. The thermostat has a user friendly interface. 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 device has implemented ZeroX technology. This technology makes sure the relay switches at 0V when turning on and off. With this technology the thermostat will have a much longer lifetime.
The thermostat can be set up with multiple associations and can be used as a master thermostat. It can control up to 10 thermostats and 10 external relays E.g wall plugs.

Prepare for Installation / Reset

Please read the user manual before installing the product.

In order to include (add) a Z-Wave device to a network it must be in factory default
state. Please make sure to reset the device into factory default. You can do this by
performing an Exclusion operation as described below in the manual. Every Z-Wave
controller is able to perform this operation however it is recommended to use the primary
controller of the previous network to make sure the very device is excluded properly
from this network.

Reset to factory default

This device also allows to be reset without any involvement of a Z-Wave controller. This
procedure should only be used when the primary controller is inoperable.

Product Usage

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.THERMOSTAT CONTROLS

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”)”.
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 waterbased  eating 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.

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.

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:
• F Floor sensor
• A Internal room sensor
• AF Internal room sensor + Floor sensor
• A2 External room sensor
• A2F External room sensor + Floor sensor
• PWER Power regulator mode (no sensor used)

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”. It can also be enabled by setting parameter 26 (open window detection) to 1.

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

1. Make sure a device is in factory reset state before including. In doubt exclude before include.
2. If inclusion still fails, check if both devices use the same frequency.
3. Remove all dead devices from associations. Otherwise you will see severe delays.
4. Never use sleeping battery devices without a central controller.
5. Dont poll FLIRS devices.
6. Make sure to have enough mains powered device to benefit from the meshing

Association – one device controls an other device

Z-Wave devices control other Z-Wave devices. The relationship between one device
controlling another device is called association. In order to control a different
device, the controlling device needs to maintain a list of devices that will receive
controlling commands. These lists are called association groups and they are always
related to certain events (e.g. button pressed, sensor triggers, …). In case
the event happens all devices stored in the respective association group will
receive the same wireless command wireless command, typically a ‘Basic Set’ Command.

Association Groups:

for use as master thermostat
4| 10| Sends Thermostat Mode set commands based on own mode to allow for use as master thermostat.

Configuration Parameters

Z-Wave products are supposed to work out of the box after inclusion, however
certain configuration can adapt the function better to user needs or unlock further
enhanced features.

IMPORTANT: Controllers may only allow configuring
signed values. In order to set values in the range 128 … 255 the value sent in
the application shall be the desired value minus 256. For example: To set a
parameter to 200 it may be needed to set a value of 200 minus 256 = minus 56.
In case of a two byte value the same logic applies: Values greater than 32768 may
needed to be given as negative values too.
