Off

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
