Take control of the heat in your home.
At night you want a cool bedroom, in the morning a warm bathroom floor – and the guest room often sits empty? Heat your home to suit your own needs.
Room by room
17.5° in the bedroom, 22° in the bathroom
The thermostat holds the temperature you set for each room – exactly as warm as you like it.
The thermostat fits into a standard wall box – in place of the old one.
Choose your thermostatWeekly schedule
Warm when you’re home. Saving when you’re not.
Set up your own weekly schedule and enjoy warmth – and energy use – tailored to you.
- ComfortA warm bathroom in the morning, a cosy living room, a cool bedroom at night.
- SavingsCut your energy costs. Lower your home’s average temperature by 1 °C and your annual heating costs drop by about 5%.
- Peace of mindStop worrying about it – the automated thermostat does the work, and you come home to a warm house.
Underfloor heating warms up slowly, so the schedule starts heating earlier – it’s already warm when you get home.
From anywhere
Control your heating from your phone
When you’re away, control the temperature at home from the phone app – switching the heating off and on remotely is easy.
The whole family can use the app, and Wi-Fi thermostats need no extra device.
Savings
1 °C cooler – about 5% lower heating costs
According to the Lithuanian Energy Agency, if your home is on average 1 °C cooler over the heating season, you’ll use about 5% less energy for heating each year.

Rough estimate: about 5% less energy for every degree you lower your home’s average temperature over the heating season (LEA, 2024). The result depends on your home, heating system and habits. In an apartment where heating costs are split by floor area, your bill may not go down.
Design
A thermostat to match your interior
Crystal or classic dial. Black, white or gold. All are designed for water-based underfloor heating, with automated energy control from your phone.
For radiators
Fit it yourself – no plumber needed
The smart radiator thermostat goes on in place of your old head. There’s no need to drain the system, and the 6 adapters in the box fit most radiators.
- Each room gets its own temperature and a personalised weekly heating schedule
- Radiators warm up faster than floors: cooler at night, already warm by morning
- Automatic heating control while you air the room
- Personalised holiday mode
- Suitable for homes with central heating
The radiator thermostat uses AA batteries. You’ll need one Zigbee hub (€39,90) for the whole home, connected to your router by cable.
With a window sensor
Save energy while you air the room
A sensor on the window automatically switches the heating off and back on while you air the room, so you save energy.
The system is controlled via your home internet connection.

Frequently asked questions
Will it work in my home?
The thermostats are designed for water-based underfloor heating. Open the manifold cabinet: on the pipes you should see white heads with wires (actuators). If they’re marked 230 V and the room already has a wired thermostat, the new one will most likely be a direct replacement. If the actuators are 24 V or your current thermostats are wireless, call us before you buy – we’ll work out together whether it’s suitable. These thermostats are not suitable for electric underfloor heating.
If you heat with radiators, choose the smart radiator thermostat. Not sure? Call us – we’re happy to advise.
How much will I save?
According to the Lithuanian Energy Agency, if your home is on average 1 °C cooler, you’ll use about 5% less energy for heating each year. If heating costs you €1,000 a year, that’s about €50. You’ll save the most in rooms you rarely use and while you’re away.
Underfloor heating warms up slowly, over several hours, so it isn’t worth turning the temperature down for short periods. It’s better to give each room its own temperature.
Can I install it myself?
Yes. The new thermostat replaces the old one – same wires, same wall box (at least 50 mm deep). English instructions with a wiring diagram are on every product page, and if you have any questions, call us – we’ll help.
Switch off the power before you start. If you’re not comfortable with electrical work, call an electrician – it’s a quick job. You can fit the smart radiator thermostat yourself – no need to drain the system.
What if the internet goes down?
The thermostat works independently: it measures and maintains the temperature itself, so your heating won’t stop if the internet goes down. Until the connection is back, phone control and app rules – such as the window sensor rule – won’t work.
Wi-Fi or Zigbee?
A Wi-Fi thermostat connects directly to your home Wi-Fi (2.4 GHz) – no extra device needed. Zigbee devices need one hub (€39,90) for the whole home. All bundles come with Wi-Fi thermostats.
How does the window sensor work?
The sensor sticks to the window frame. In the app, you create a rule: when the window opens, that room’s thermostat is set to its lowest temperature and the heating stops; when it closes, the usual temperature is restored. The rule works via the internet.
Floors cool down slowly, so you save the most when a window stays open for longer. The smart radiator thermostat detects an open window by itself.
Can the whole family control the heating?
Yes. Add family members in the app – each of them can control the heating from their own phone.
How much is shipping, and how do returns work?
Shipping is free on all orders. For orders placed by 31 December 2026, you can return an item that hasn’t been installed, in its original packaging, within 30 days of receiving it; you pay for the return shipping. Full details are in our refund policy.
