3. Before you start
Positioning the uSense :
The room unit must be positioned taking into
account the following factors:
• On an internal wall
• Away from draughts
• 1.2-1.5 m from the floor
• Not behind doors, bookcases or other objects
• Not in direct sunlight
•
In a room where the user spends most of their time
• Away from heat sources (fireplace, radiators, light,
candles, etc.)
• The maximum cable length from the gateway
to the room unit is 50 m
Prior to installation make sure to:
1. Isolate the power to the heating and control
system and make safe (remove or lock o fuse)
2. Check that the power has been isolated
using suitable test equipment.
Wear appropriate Personal Protection Equipment
e.g. protective gloves, safety footwear etc.
Warning: High Voltage wiring must
only be installed and worked on by
a suitably qualified person.

4. Installation
1. Choose a suitable location for the
uSense 2 thermostat (see Before
you start section on page 5)
2. Remove existing thermostat
(if applicable)
3. Fix the room unit backplate to the wall
using the screws provided
4. Either use existing thermostat wires
or run new wires from the gateway
(there is no polarity - either wire can
be connected to either position)
5. Trim the wires coming out of the wall,
connect them into the connector block on
the room unit backplate
continued opposite
7
6. Slacken the screws at the sides of the
connectors and insert each wire into the
top at either side of the connector, then
re-tighten the screws
7. Make sure the wires are as flat as possible
against the back plate so that they do
not interfere with the controller when it is
mounted in position
8. Press the room unit onto the backplate until
it clicks into place
9. Connect the other end of the wires
to the R-BUS or OpenTherm terminals in
the boiler (or gateway if fitted). There is no
polarity - either wire can be connected to
either position
10. The connections between the
room unit and boiler or gateway
are low voltage. 230 V will
damage the room unit and
gateway!

5. OpenTherm hot water control
The uSense room unit will override the hot water temperature controls
on your appliance (OpenTherm only).
1. The room unit will automatically default the hot water temperature to 60 °C
when connected by OpenTherm
2. The room unit will automatically default the heating flow temperature to 80 °C
when connected by OpenTherm
3. These settings can be adjusted to your required comfort level using the uSense 2
room unit only (the appliance controls and App can’t adjust these settings
when the room unit is connected with OpenTherm).

6. Outdoor sensor
Connecting to an outdoor sensor
If an outdoor sensor weather compensator is connected in conjunction
with the uSense (OpenTherm installations only) you can ONLY adjust the
heating curve on the uSense App (you CANNOT adjust using the room
unit or appliance controls).

2. Click on the installer menu
3. Click on advance settings

6. Click OK
7. Click on heating curve
8. Change the curve to suit the requirements of the user in accordance
with the recommendations of the sensor manufacturer
9. Do not adjust any other settings in the Advanced Feature menu,
as they may aect the correct operation of the appliance
10. Either completely close the App or re-enter the code to cancel the
access level so that your customer can’t adjust important settings.
