1. INTRODUCTION
Congratulations on the purchase of your new UWG5® WiFi
LED touch thermostat. We hope that you will enjoy the user-
friendly touch interface and the intuitively designed app
that enables you to set up your thermostat to suit your daily
routines.
Quick adjustments
Simply tap the capacitive touch buttons on the thermostat
gently with your ngertip if you want to make quick temper-
ature adjustments or toggle the schedule on or off. In many
cases, scrolling text will appear to help explain the changes.
Get connected
The WiFi-enabled thermostat allows you to set up, monitor,
and control the thermostat from your mobile phone.
Forgot to set vacation mode? Just connect remotely and
adjust any setting as required.
Tips for saving energy
Lowering the temperature while your home is unoccupied
will reduce your energy costs without reducing the comfort
of a heated oor.
Set up your thermostat to turn on your underoor heating
system during preset periods to save energy. You can easily
use and customize one of the predened schedules, or you
can create your own schedule from scratch.
Comfort and intelligence
The thermostat automatically adjusts heating start times
to ensure that the required temperature is reached at the
beginning of a scheduled event rather than too late. After a
few days, the intelligent adaptive function will learn when
the heating needs to be switched on to provide maximum
comfort in your specic environment.
Talk to your thermostat
Make it even easier to adjust your thermostat by enabling
voice control. If you have Google Assistant or Amazon Alexa
devices in your home, you can connect your thermostat to
these as well. This is easy to do in the app.
When connected, try saying “Alexa, make the bathroom
warmer” or “Hey Google, make the bathroom warmer.”
Enjoy!
Apple App Store Google Play
Download the UWG5® app from Google Play or the Apple App
Store and follow the app guide for setupto get started.

3. START-UP WIZARD
When the thermostat has been installed and turned on for the rst time, or after you have performed a factory reset,
the thermostat will run a start-up wizard. The wizard guides you through a basic setup process to ensure that you
have the right settings and a thermostat test is performed.
The start-up wizard gives you the option to adjust four settings, followed by the GFCI test.
The dots in the left column shows the setting number to help you navigate your way through
the guide.
You can choose to complete this start-up process on the thermostat or via the app.
This manual describes how to use the thermostat.
If you want to use the app, go to the section on how to connect with Bluetooth.
The start-up wizard takes you through the following steps:
1. Unit
2. Sensor
3. Time
4. Protection
After the last setting, you will be instructed to perform a GFCI Test. Once
the test has been passed, the thermostat is ready to use.
To see a description of the setting, you can tap the text or wait 10 sec-
onds. The full setting name and its number will scroll across the screen
from the right.
