Heatit Z-trm2fx Thermostat For Electrical Floor Heating Installation Guide

HEATIT Z-TRM2fx Thermostat for Electrical Floor Heating Installation Guide

IMPORTANT

PLEASE READ THIS BEFORE INSTALLATION
This Heatit device is certified by Pepper One Gmbh according to the requirements set forward by the Z-Wave Alliance and
Silicon Labs. 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 for such a device. We do not give any guarantee towards integration.

PRINCIPLES FOR REGULATION

Heatit Z-TRM2fx is designed for controlling electrical heating cables and electrical radiators/convectors. The thermostat uses an external temperature sensor. 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.

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.

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

BEHAVIOR WITHIN THE Z-WAVE NETWORK

This product can be operated in any Z-Wave network with other Z-Wave certified devices from other manufacturers. All nonbattery operated nodes within the network will act as repeaters
regardless of vendor to increase 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 wireless network to communicate with the devices of this network. Devices can also be removed from a network. Both add and remove process are initiated by the primary controller of the Z-Wave network.

This controller will be turned into a mode for adding or removing devices. Please refer to your primary controllers manual on how to turn your controller into add or remove mode. Only if the primary controller is in add or remove mode, this device can be added or removed from the network. When the device is removed from the network, it will set the device back to factory default.

If the device already belongs to a network, follow the remove process before adding it in your network. Otherwise, the adding of this device will fail.

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.

To be able to to read the Power Metering, the load needs to be connected to both heating L + N.
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. 1: Left (Up)
2: Center (Confirm)
3: Right (Down)

ADDING/REMOVING

To add or remove the thermostat to your home automation gateway, press Center (confirm) for 10 seconds.

The display will show OFF. Press Right (down) 4 times till you see Con in the display. Now start add/remove device in your home automation software. Start adding/removing mode by pressing Center (confirm) for approximately 2 seconds. Adding/removing Mode is indicated in the display by some “circling” LED segments in the display until the timeout occurs after 20 seconds or the module has been added/removed in the network. Confirmation will show Inc/EcL in the display. If adding/removing fails, Err (error) will appear. Leave programming mode by choosing ESC in menu. Your thermostat is ready for use with default settings.

PROGRAMMING YOUR THERMOSTAT

To activate the programming mode, press Center (confirm) for 10 seconds. Now the display will show OFF.
Now you are in programming mode. To scroll up and down in the menu use button 1 and 3 (left and right) to navigate. To enter submenu press Center (confirm). Always confirm your setting by pressing Center (confirm) for 2 seconds.

Depending on your choice of sensors, the menu will change.

NODE INFORMATION FRAME

The Node Information Frame is the business card of a Z-Wave device. It contains information about the device type and the technical capabilities. The inclusion and exclusion of the device is confirmed by sending out a Node Information Frame. Beside this, it may be necessary for certain network operations to send out a Node Information Frame

ASSOCIATIONS

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. sensor reports, …). In case the event happens all devices stored in the respective association group will receive a common wireless command.

Association Groups (Multi Channel support)

When using Heatit Z-TRM2fx in a Multi Channel environment:

Association Groups (when no Multi Channel support)

When used in a system with no Multi Channel support:

Setting and Removing Associations

Associations can be assigned and removed via Z-Wave commands.
