Product Description

Shelly BLU TRV is a smart thermostatic radiator head with Bluetooth connectivity. It controls the temperature of a room by changing the flow of the hot water through the radiator. If needed, the temperature can be changed at any time by turning the Device rotating knob to the left or right, or through your mobile phone, tablet, or PC. The Device can also maintain the room temperature according to a set weekly schedule. It is powered by 2 AA, 1.5 V batteries.

User interfaces

Reset button

The reset button is on the back of the TRV’s head (Fig. 1/7). To access the button, the head must be separated from the black plate (See Fig.

To press the button, use a pointed object, such as a paperclip, pen tip, or a small screwdriver.
Press once to pair the BLU TRV with another Bluetooth device.
Press and hold for 30 seconds to factory reset the Device.
Factory reset will disconnect the Device from the BLE Gateway Gen3 and delete all data.

Rotating knob

The rotating knob is the outer turning shell of the TRV head. It is pro- grammed to setup and control the Device based on the number of ro- tational steps. For more details, see section Using the rotating knob to operate the device.

LED display

The TRV has a 7-segment LED with 3 indication modes:

Steady on
Blinking

Installation instructions

CAUTION! Before beginning the installation, turn off the radiator and make sure it has cooled down.
CAUTION! Mount the TRV head onto the backplate ONLY AFTER the backplate is mounted and secured on the radiator valve.
CAUTION! Risk of water leakage. If you do not have a thermostatic valve installed on your radiator, call a specialist to replace your valves. Compatible valves If not sure whether you need an adapter for your radiator valve, check the list of compatible radiator valves by brand and model here: https://shelly.link/blu/trv_compatible_valves If your radiator valves are not compatible, use one of the adapters included in the box. (Fig. 2).

Installing the backplate

If your radiator needs an adapter, mount the suitable one (Fig. 2)
To install the backplate onto the radiator valve, turn the mounting ring clockwise by hand (Fig. 3)
- Make sure that the alignment mark on the backplate points upward
Tighten carefully the mounting ring by using an adjustable wrench.

Do not over-tighten the ring!

Mounting the TRV head

The device comes with batteries installed. Before mounting the TRV head onto the backplate, remove the isolation tab from the battery compartment.

Align the head and backplate notches (Fig. 4). Then, insert the head on the backplate.
Apply moderate pressure with your palm on the front cap and turn the head clockwise until it clicks. (Fig. 5).

Calibrating the Device

After successfully mounting the head, the TRV automatically starts calibration by turning its motor in both directions. The display shows.
If the calibration is successfully completed, the display shows briefly .
If the calibration fails, the display shows briefly .

If the Device does not start calibration, it likely means that the head is not fully tightened onto the backplate. Try to turn it farther. If this does not resolve the issue, repeat the steps from the beginning. To dismount the TRV head, press the front cap and turn the head counterclockwise until it is released (Fig. 6).
If the Device is installed with an adapter and reports failed calibration, you may need to install a pin extender from the adapter set (Fig. 2). Once the calibration is completed successfully, the Device can be used to control temperature.

Using the rotating knob to operate the device

To wake up the LEDs, turn the knob at least one step in any direction. The display shows the current temperature.

Setting the target temperature

To increase the temperature, turn the knob to the right.

To decrease the temperature, turn the knob to the left.
- Each knob step changes the temperature by 0.1 °C
Once the target temperature is reached, stop turning the knob. After 3 seconds, the TRV applies the set temperature, and the display con- firms the new temperature value

Turning On/Off Boost mode

Boost temporarily raises the heating power to quickly increase the room temperature.

To turn on the Boost mode, turn the knob for more than 10 steps to the right. The display shows briefly.

To turn off the Boost mode, turn the knob for more than 10 steps to the left. The display shows briefly.

Adding the Device to the Shelly Cloud application

To add the Device to the Cloud application, first you need to pair it with a BLU Gateway Gen3.

Power up the Gateway by plugging it into a standard USB Type-A port. The blue LED lights up showing that the device is in Access Point (AP) mode.
To add the Gateway to your Shelly Smart Control, open the applica- tion, select Add a new device, and follow the instructions in the app. Once the Device is added to your account, the green LED lights up.
To access the TRV menu, turn the rotating knob in this order: Left, Right, Left, Right. You can start in either direction.

The display will show . Turn the rotating knob to the right until the display shows . In 3 sec, the Device will enter Pairing mode for 30 seconds indicated by a blinking indicator. Alternatively, you can activate paring mode by pressing the reset button once. If pairing times out, the display shows for 3 seconds. 4 On the BLE Gateway Gen3, press the Pair button. 5 If the pairing is successfully completed, the TRV display shows . The Device will appear in your Shelly Smart Control app as a BTHome component of the BLE Gateway Gen3.

To make sure that the Device is running on the latest firmware version, go to Device settings > Firmware version > Update. For more details on how to control the Device using the Cloud, refer to the https://shelly.link/app-guide

Replacing batteries

The Device is powered by 2 AA, 1.5 V batteries.

We recommend using Lithium/Iron Disulfide (Li/FeSz) batteries.
The Device may not operate with rechargeable batteries.

To disassemble the TRV head, press the front cap and turn the head counterclockwise until it is released (Fig. 6).

Using your thumbs, press and slide the battery cover up until it pops open (Fig. 7).
Remove the exhausted batteries and dispose of them according to your local regulations.
Insert the new batteries following the polarity marking on the battery cover.

Push and slide the battery cover down until it locks.
Assemble the TRV head back onto the backplate (Fig. 5).
