Before you start Positioning the uSense 2: 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 off 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. 1.5 m 1.5 m

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!

8 5. OpenTherm hot water control The uSense 2 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).

9 6. Outdoor sensor Connecting to an outdoor sensor If an outdoor sensor weather compensator is connected in conjunction with the uSense 2 (OpenTherm installations only) you can ONLY adjust the heating curve on the uSense 2 App (you CANNOT adjust using the room unit or appliance controls). 1. Open the Baxi uSense 2 App 2. Click on the installer menu 3. Click on advance settings 4. Enter service code 0012 Remember to re-enter this code to disable installer access when you finish adjusting the heating curve 5. You will see a message ‘Your access level has been updated’ 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 affect the correct operation of the appliance 10.
