The smart radiator thermostat: what is it?

A smart radiator thermostat is an intelligent device that is fitted to hot-water radiators to control the temperature precisely and individually.

Unlike a conventional thermostatic radiator valve, it can be controlled from your smartphone. You can set the desired temperature in each room fitted with a smart radiator thermostat head and tailor your heating to your routine, so you can stay in control wherever you are.

This provides greater comfort in everyday life and reduces energy wastage. 

The right temperature at the right time moment

The Smart TRV simply replaces your existing thermostatic radiator valve and is compatible with most hot-water radiators supplied by a gas, oil or wood-fired boiler, or a heat pump. 
Thanks to its built-in intelligence, it analyses the thermal behaviour of your home in order to anticipate your heating needs and to reach the desired temperature at just the right time. Each room is heated according to your actual needs and lifestyle. 
This means you can enjoy personalised comfort throughout your home whilst minimising unnecessary energy consumption.

Choosing the right smart radiator thermostat 

The choice of a smart radiator thermostat head depends on several key criteria: control accuracy, ease of use, battery life, features and compatibility with your heating system. 

Window-opening detection function: The smart TRV detects when a window is opened by analysing changes in the room temperature and temporarily stops heating the room.

Quiet operation: Discreet and quiet, the smart radiator thermostat operates at less than 30 dB* to ensure thermal comfort without any distracting noise, even in living rooms or bedrooms.  

Locking profiles: Three locking profiles are available, depending on the type of housing: partial, intermediate or full.  

Absence management: the Smart TRV allows you to set an appropriate temperature when the property is unoccupied and to adjust the minimum temperature.  

Child lock: a child safety feature prevents unwanted changes to the set temperature, giving occupants peace of mind and keeping the chosen settings in place.  

Humidity level: via the Delta Dore app, the Smart raditor thermostat allows you to view the humidity level in the room where it is installed. Your customers can then see when they need to ventilate the room to improve air quality.  

*or quieter than a fridge, which averages 40 dB.

The 3 benefits of the Smart TRV:

✔️ An ideal temperature in every room: you no longer need to think about it – your living areas are heated to 19°C and your bedrooms to 17°C, for example
✔️ Remote control: once your thermostatic radiator valve has been paired with your Delta Dore smart home hub, the programming possibilities are endless via the Delta Dore app
✔️ ️ A solution designed to last: With a battery life of up to two years, the Smart TRV minimises the need for maintenance.
✔️ Compatible with your installation: The Smart TRV works with many hot-water heating systems and is easy to integrate into your existing installation. 

 

A first step towards a smart home

The Smart TRV really comes into its own when integrated into the Delta Dore ecosystem. By coordinating control of your heating, roller shutters and hot-water tank, your home automatically adjusts its energy consumption to suit your lifestyle. 
The heating runs only when needed, the roller shutters help retain heat in winter, and the hot-water tank operates at optimised times. This coordinated management helps improve comfort while keeping energy consumption down.

Result: energy savings of up to 30%* compared with a system without smart control.

By connecting it to your system, you can enjoy new features that make your daily life more comfortable:

• Heating control
• Roller shutter and blind control
• Lighting control
• Security system control
• Automation of everyday routines.
• The Delta Dore app makes your home more comfortable, smarter and more energy-efficient on a daily basis.
