The Reina Square Thermostatic WiFi Element brings smart, app-based control to a compatible Reina electric or dual-fuel radiator. Connecting to the Smart Life app over WiFi, it lets the radiator be scheduled, monitored and adjusted remotely from a smartphone, without needing to be in the room.
Behind the app connectivity sits a genuinely versatile thermostat: five heating modes (Room, Radiator, Boost, Anti-Freeze and LST), a wide 7–30°C room temperature range, and a Heat Plus mode that extends the internal fluid temperature up to 75°C for faster warm-up. Safety features include child lock, frost protection and an IP44 rating for bathroom use.

🔴 Compatible radiators only
This element must only be fitted to a Reina radiator or towel rail approved for electric or dual-fuel operation. Confirm compatibility with the specific radiator model before ordering.
Smart Life app control
Pairing over WiFi with the Smart Life app (iOS and Android) lets the radiator be turned on, scheduled or adjusted from anywhere, so heat can be ready for arrival home without leaving the element running all day.
Five dedicated heating modes
Room, Radiator, Boost, Anti-Freeze and LST modes cover everyday comfort, fast warm-up, frost protection and low-surface-temperature operation from a single element, rather than relying on one fixed heating curve.
Heat Plus for faster warm-up
Standard operation covers 30–70°C internal fluid temperature; switching on Heat Plus extends this to 75°C for quicker heat-up on colder days or larger rails.
Child lock & frost protection
A child lock prevents accidental setting changes at the unit itself, while automatic frost protection keeps the rail lightly warmed in unoccupied rooms to protect against freezing.
Open window detection
The element senses a sudden ambient temperature drop consistent with an open window and automatically reduces output, cutting wasted energy during ventilation.
2-hour boost timer
A dedicated 2-hour boost temporarily raises output for quick warmth or towel drying, then reverts automatically to the scheduled setting.

What app does this element use?
The Square Thermostatic WiFi Element connects to the Smart Life app, available for iOS and Android, over your home WiFi network. Once paired, it can be scheduled and adjusted remotely.
What is LST mode?
LST (Low Surface Temperature) mode limits the surface temperature of the radiator, reducing burn risk in settings such as homes with young children, the elderly, or vulnerable users where a cooler-to-the-touch rail is preferred.
What does Heat Plus do?
Heat Plus extends the internal fluid temperature ceiling from the standard 70°C up to 75°C, delivering faster warm-up on larger rails or in colder rooms.
Can I fit this to any radiator?
No. It must only be fitted to a Reina radiator or towel rail approved for electric or dual-fuel use. Check the specific radiator's product page for confirmed compatibility before ordering.
Does it work if my WiFi goes down?
The element continues to operate on its last confirmed schedule and thermostat setting using local control at the unit; app-based remote adjustment and scheduling changes require an active WiFi connection to resume.
