2.2 Introducing the uSense
See
Reference to other manuals or pages in this manual.
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.

2.6.2 Customising the main screen display
You can configure the main screen of the display by adding two informa
tion boxes on the screen, one to the left and one to the right of the rotary
dial.
The information boxes can show:
Time and date
Detailed information about your system
You can also change the display of the temperature to show the current or
target temperature.
For more information, see
Main screen setting, page 23
Display current or target temperature, page 23
In case you have multiple zones in your heating system, it is possible to
control temperatures in multiple zones. A zone can be a room or, for ex
ample, the ground or first floor. The zones are named CircA, CircB etc. by
default. These factory names can be changed in any name you prefer.
You can change the names on the uSense or in the app.
