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
has SmartStart. 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
230VAC.
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.
STATEMENT REGARDING PRODUCTS FROM MULTIPLE MANUFACTURERS
Please read this before installation
This device may be used with all devices certified with the Z-Wave PlusTM
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.
INSTALLATION
Installation must be done by a qualified electrician in accordance with the
National Building codes. Before installation, disconnect the power to the
device from the mains. During the installation of the device, power to the
device 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 may now be
removed.
Connect the wires to the thermostat terminals: Use 1,5mm² or 2,5mm² according to load.
| HEATING (N) | Heating cable connection (Neutral) |
|---|---|
| N | Power connection (Neutral) 230VAC |
| L | Power connection (Live) 230VAC |
| HEATING (L) | Heating cable connection |
| FLOOR SENSOR | NTC type (10, 12, 15, 22, 33 or 47kΩ). Default 10kΩ. |
| FLOOR SENSOR | NTC type (10, 12, 15, 22, 33 or 47kΩ). Default 10kΩ. |
Next, position the thermostat and fasten it onto the wall mounting 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 left and right sides. The front cover should now fir firmly on both sides. To be able 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.
ADD/REMOVE
- Press Center (confirm) for 10 seconds. The display will show OFF.
- Press Right (down) 5 times until you see Con in the display.
- Start the add/remove device process in your primary controller.
- Start to add/remove mode 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.
