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.  

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.

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.
