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 230V. The thermostat may be used for water based

heating if the thermostat is linked to the Heatit Z-Water.

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 used with all devices certiﬁed with the Z-Wave Plus™

certiﬁcate and should be compatible with such devices produced by

other manufacturers. Every primary controller is diﬀerent depending on

the manufacturer, their target consumer 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.

3. 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.

The primary controller 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.

4. QUICK START

1. Switch oﬀ the mains supply (disable the fuse).

2. Open the wall switch box.

3. Connect wires according to the labeling described in

chapter 5 ”Installation”.

4. After verifying the connections, switch the mains supply back on.

5. Set the primary controller in add mode (security/non-security).

6. Press and hold the center button until “OFF” is shown on the

display (approx. 10 seconds).

7. Press down button until you reach “CON”, press and hold until the

display shows a rotating light pattern.

8. The thermostat will display “INC” when the thermostat is

successfully added.

NB! If adding/removing fails, Err (error) will appear.

5. INSTALLATION

Installation must be done by a qualiﬁed electrician in accordance with

the National Building codes. Before installation, disconnect any power to

the thermostat mains. During installation of the thermostat, power to the

thermostat must be disconnected AT ALL TIMES!

5.1 CONTROLS

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.

Default 10kΩ

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.

6. ADD/REMOVE

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 Heatit Z-TRM3 to a Z-Wave network.

6.1 METHOD 1: STANDARD (MANUAL)

1. Press Center (conﬁrm) for 10 seconds. The display will show OFF.

2. Press Right (down) 5 times until you see Con on the display.

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

4. Start the add/remove mode in the Heatit Z-TRM3 by pressing

Center (conﬁrm) for approximately 2 seconds.

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

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”.

6.2 METHOD 2: SMARTSTART (AUTOMATIC)

SmartStart enabled products can be added into a Z-Wave network

by scanning the Z-Wave QR-Code present on the product with a

controller providing SmartStart inclusion. No further action is required

and the SmartStart product will be added automatically within 10

minutes of being switched on in the network vicinity.

The Z-Wave QR-Code locations may be found in Chapter 20

”Z-Wave QR-Code/DSK”.

7. FACTORY RESET

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.

The device will display rES for 10 seconds while performing a factory reset.

When rES no longer is displayed, the thermostat has been reset.

7.1 STARTUP

AFTER POWERING UP THE THERMOSTAT FOR THE FIRST TIME, ALL

PARAMETERS WILL HAVE DEFAULT SETTINGS.
