About this product
The Shelly BLU TRV 3-pack is a complete kit for a three-radiator apartment or house in Chisinau and across Moldova. The box holds three Shelly BLU TRV thermostatic heads and one BLU Gateway Gen3, so every room gets its own temperature control from day one.<br><br>Each head mounts directly on M30x1.5 valves, and the bundled adapter set covers Danfoss RA, RAV and RAVL, Caleffi, Giacomini and M28x1.5 variants. The head runs on two included 1.5 V AA batteries with an estimated life of up to two years and shows temperature on a small seven-segment LED display with a fine 0.1 degree step.<br><br>The BLU Gateway Gen3 links the three Bluetooth heads to WiFi and Shelly Cloud, unlocking schedules, boost mode and whole-home automations from a single app.

Where it works
Use cases
Warm living room at night, cool bedroom, office only on workdays.
Each head keeps its own temperature schedule via the gateway.
You air the room in the morning and the radiator stops heating cold outside air.
A Shelly BLU window sensor closes the radiator when a window opens.
Before a bath you trigger boost in the bathroom from the app.
Boost mode opens the valve for a short, intense warm-up.
