2.1 Symbols used in the manual
This manual uses various symbols to draw attention to special instructions.
We do this to improve user safety, to prevent problems and to guarantee
correct operation.

Reference to other manuals or pages in this manual.
2.2 Introducing the uSense
Intended use. The uSense is designed to operate as a room thermostat
with the possibility to operate your heating system. It has a Wi-Fi connec
tion to be able to connect to the Internet, making it possible to operate the
uSense with an app on a mobile device.
Warning
Do not use the uSense for systems that are not in accordance
with the intended use.
A simple user interface. Like many other interfaces you have to scroll
through menus, select and enter options and confirm changes. The
uSense has only two buttons that you can either short-press or long-press.
There is one rotary dial to scroll forward or backward. It’s as easy as that!
Controlling the temperature. Your plans change. No problem, control the
temperature as you wish, in manual mode or schedule mode. You can
even be flexible by switching between three schedules. Do you prefer us
ing your mobile device anywhere in the house? The uSense app is availa
ble for iOS, Android and Windows.
What do I do when I …? I want to …? How do I …? Are you going away
for a holiday? Do you want to make a fire in your fireplace? Do you need a
hot water boost? Or do you want a short temperature change? You can
find most answers in the "General use" chapter.
