Heatit Z-TRM3 Wi-Fi Thermostat
INTRODUCTION
Heatit WiFi thermostat is an electronic thermostat for electrical underfloor heating. The thermostat has a simple user interface and can be easily programmed via the capacitive buttons. The color screen displays an accessible user interface. The thermostat has a built-in WiFi chip that allows you to control it from a user-friendly app. The ”Heatit WiFi” app is available on Google Play and in the App Store. Works with Amazon Alexa and Google Home (pending). If you are installing multiple thermostats in the same house, you may copy the settings from one thermostat to the next. This simplifies installation. Heatit WiFi thermostat 16A is equipped with a single-pole switch and fits into most common frames (e.g. System 55, Elko RS16, Schneider Exxact). The thermostat can withstand a load of max 16A/3600W at 230VAC. We recommend a contactor for loads above 13A. The thermostat may be connected to an external sensor. The thermostat is designed for electrical heating.
INSTALLATION
Installation must be done by a qualified electrician in accordance with national building codes. Before installation, disconnect the power to the device from the mains. During installation of the device, power to the device must be disconnected AT ALL TIMES.
Release the front cover by pressing a screwdriver (e.g) into the ejector latch at the bottom of the thermostat. Be careful not to damage the thermostat.
Connect the wires to the thermostat terminals:
- L Power connection (Live) 230VAC
- LOAD (N) Heating Cable connection (Neutral)
- LOAD (L) Heating Cable connection (Live)
- N Power connection (Neutral) 230VAC
- PILOT Pilot Wire (if applicable) 230VAC
- SENSOR Floor temp sensor, NTC type
Next, position the thermostat and fasten it onto the wall mounting box using 2-4 screws. Open the frame holder spring, position the frame and reattach the spring. Then attach the front, making sure the connectors between the front and back are correctly placed. Press the front carefully until it snaps into place.

WIFI CONNECTIONS
Start the ”Connect to cloud” process from the WiFi settings menu. Launch ”Add thermostat” in the app on your phone. The thermostat will show two 3-digit PIN codes. Enter these into your phone application. Next, enter your WiFi password in your app. When the ”Add thermostat” process is finished, the thermostat will reboot. Subsequently, you will be able to control your thermostat WiFi settings through the app on your phone.
