heatit Z-TRM3-W Z-Wave Electronic Thermostat 
Instruction Manual

IMPORTANT

PLEASE READ THIS BEFORE INSTALLATION

This thermostat is tested and certified by Pepper One Gmbh according to the requirements put forward by the Z-Wave Alliance. This is a Z-wave Plus product with the 500 series chip. If the product does not work with your gateway, then the gateway manufacturer has not made an integration or implemented such a thermostat with their gateway. We do not give any guarantee towards integration.

PRINCIPLES FOR REGULATION

The Heatit Z-Wave is designed for controlling electrical heating cables and electrical radiators/convectors. The thermostat has built in temperature sensors and has 3 algorithms for temperature compensation.
After you have set the temperature, the thermostat will use a hysteresis to regulate the temperature. The hysteresis is adjustable.

TEMPERATURE SHOWN IN DISPLAY

The temperature shown in the display is the actual temperature for floor sensor and the external room sensor. You are able to calibrate the sensor values.
When using the built in room sensor, the temperature shown is the set point. When using the built in sensor, the thermostat can seem somewhat inaccurate. This is due to heat generation inside the thermostat, draft and other external influences.

If the thermostat is to be used with waterbased heating systems, you have to use an external sensor.

Z-WAVE THERMOSTAT – SETUP

This manual describes the most essential functions and technical specifications of the thermostat.
These instructions help the user to control the thermostat, and the electrician to install and setup the thermostat.

INSTALLATION

Installation must be done by a qualified electrical installer in accordance with the National Building codes. Before installation, disconnect any power to the thermostat’s mains. During installation of the thermostat, power to the thermostat 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 can now be removed.

Now connect the wires to the thermostat’s terminals: Use 1,5mm² or 2,5mm² according to load.

HEATING (N) Heating cable connection (Neutral)
N Power connection (Neutral) 230V
L Power connection (Live) 230V
HEATING (L) Heating cable connection (Live)
PILOT 230V pilot signal (ECO temp)
FLOOR SENSOR NTC type (10, 12, 15, 22, 33 or 47kΩ).
Default 10kΩ.
EXTERNAL SENSOR NTC type (10, 12, 15, 22, 33 or 47kΩ).
Default 10kΩ.

Next, position the thermostat and fasten it onto the wall’s mounting box using 2-4 screws. Position the frame, 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 left and right side. The front cover should now be firmly fixed on all sides.

NOTE! Top cover has to be installed when the thermostat is connected to mains. The thermostat is not SELV product.
All voltage parts are considered as 230VAC.

STARTUP

AFTER CONNECTING THE POWER TO THE THERMOSTAT FOR THE FIRST TIME, ALL PARAMETERS WILL HAVE DEFAULT SETTINGS.

CONTROL

The thermostat is controlled by three touch sensitive capacitive buttons.
You only need to touch lightly to activate the buttons.

TECHNICAL DATA

1. CHOICE OF SENSOR

The thermostat has a range of choices when it comes to sensors. To get to the menu you have to press Center (confirm) for 10 seconds, then press Right (down) once and an A shows in the display. Then press Center (confirm) again and you can choose one of these modes, while moving up and down with buttons Left or Right.

F Floor sensor
A Internal room sensor
AF Internal room sensor + Floor sensor
A2 External room sensor
P Power regulator
FP Floor sensor + Power regulator
A2F External room sensor + Floor sensor

When you have decided on the sensor mode you want to use, press the Center (confirm) button. If you choose F or AF 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.

In power regulator mode the thermostat regulates the power consumption by switching on and switching off in time intervals. Switch-on and switch-off is done according to a time proportional control cycle of 30 minutes. This means that the heating element is switched on and off in a pulse/pause interval. This functionality is not supported in Z-Wave.

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).

2. SELECT THE RIGHT OHM VALUE FOR YOUR EXTERNAL/ FLOOR SENSOR

The following values are available: NTC type (10, 12, 15, 22, 33 or 47kΩ). Default 10kΩ. The function is only active when an external sensor is connected. Confirm with Center (confirm) button.

In this mode you are able to adjust the displayed temperature. If the thermostat of some reason (or sensor) is not calibrated properly you are able to make minor changes to the temperature. You are able to raise/lower the set point by up to 4°C. Confirm with Center (confirm) button.
This function is only available for the floor sensor and external room sensor. When calibrating the room sensor, only the setpoint is changed. The display will not change.

4. BRIGHTNESS

Use Left and Right (up and down) button to adjust the brightness between 0-9. Confirm with Center (confirm) button.

5. INCLUSION/EXCLUSION

To include the thermostat to your home automation gateway, press Center (confirm) button for 10 seconds.
The display will show OFF. Press Right (down) 4 times till you see Con in the display.

Now start add device in your home automation software. Start inclusion mode by pressing Center (confirm) button for approximately 2 seconds. The inclusion/exclusion icon will appear in the display.
Confirmation will show Inc/EcL in the display.
If inclusion fails, Err (error) will appear.

6. HYSTERESIS (DIF)

In this mode you are able to make changes to the hysteresis in the thermostat. This means that you can changes the hysteresis from 0,3°C up to max 3,0°C. Confirm with Center (confirm) button. Default setting is 0,5°C. When using a water based heating, the recommended hysteresis is a minimum of 1,0°C.

7. MIN/MAX TEMPERATURE SETTINGS

FLO Min Floor temperature
FHI Max Floor temperature
ALO Min Air/room temperature
AHI Max Air/room temperature
PLo Min temperature in Power Reg Mode Confirm with Center (confirm)

8. HEA Choose whether the thermostat is to be used for heating or cooling.

ESC Leaving programming mode. Confirm with Center (confirm) button.

9. STANDBY AND MAIN SCREEN

When the thermostat remains untouched for a while, it will automatically go to standby screen. Standby screen shows the temperature in the room or floor if the thermostat is connected to external sensors. By pressing Left or Right (up or down) button the setpoint will be shown in the display. If the internal room sensor is used, the thermostat display shows the setpoint.

10. DISPLAY ON/OFF – DON/DOF

Activate by pressing Left and Center (up and confirm) button for 10 seconds. The display light is temporarily activated if one of the buttons is pushed.

In case doF is activated, the screen will be blank (can be used if installed where people are sensitive to the light of the display). A very nice feature when used in a bedroom. When touching the display, the screen lights up.

11. CHILDLOCK – LOC

By pressing Left and Right (up and down) buttons for 10 seconds, child lock will be activated and no changes can be made. Trying to make changes causes the LOC text to appear in the display. Child lock is deactivated by pressing Left and Right (up and down) buttons for 10 seconds. OPn will appear in the display

12. FACTORY RESET – RES

By pressing buttons Right and Center (down and confirm) for 20 seconds, the thermostat will perform a complete factory reset. NB! Please use this procedure only when the primary controller/ gateway is missing or otherwise inoperable.

13. CO/ECO MODE

The thermostat has 2 main programs, CO – comfort mode and ECO – economy mode. When Center (confirm) button is pushed for 2 seconds you switch between the 2 modes. You would normally have 2 different set-points for the different modes.

CO – mode: Is used for normal use. Example: 21°C.
ECO – mode: Is a setback mode that you can use if the thermostat is installed in a room or a house that is rarely used.

The ECO-mode can also be activated by the pilot wire if this is connected. Example: 18°C.
Some gateways also support switching between CO/ECO mode.
In most circumstances, the CO/ECO function can be regarded as a home/away function.
