When considering Thermal Comfort, what aspects are the most important? Is it general room temperature? Floor temperature? Climate control? Or maybe something else? Whatever the need, HELTUN guarantees to take care of it for you.

Powerful, efficient and well-designed, HELTUN is the thinnest and most stylish thermostat on the market. Featuring a crystal-clear glass window, its fire and short circuit resistant recycled-plastic casing is only 9mm thick.

HELTUN integrates seamlessly into your interior design and is available in 24 combinations: 4 frame colours (Silver, Chrome, Black and White) and 6 glass types (White, Black, Yellow, Green, Red, Blue), you can choose any style that suits your taste.

Internal sensors
In addition to temperature control sensors, HELTUN thermostat also feature built-in humidity and light sensors.

Additional sensors that help you save energy
When an electronic device carries out its function, a certain amount of heat is generated. As a result, the ambient temperature is usually reported incorrectly, with merely a 1.5-2.0 degrees Celsius precision. HELTUN engineers added two additional internal sensors that consider excess heat generated from the device itself, whilst a special compensating software calculates the ambient temperature with an incredible 0.2-0.3 degrees Celsius precision.

You can connect an NTC temperature sensor to our device (3m long and 3.5mm thick NTC sensor is included in the box) or use your existing sensor to control floor/roof temperatures. This sensor can be installed under the floorboard, on the roof or under the decking, allowing you to accurately measure the chosen surface temperature.

It is fully compatible with NTC sensors from other manufacturers, so there is no need to replace existing sensors from your old thermostat when switching to HELTUN.

You can also control HELTUN by connecting it to an external system, such as linking it to the house alarm system, which will automatically reduce the ambient temperature when the house is empty.

Know how much energy you are using
With our HELTUN built-in power consumption system, you can monitor precisely how much energy was used during any particular day, week or month. This feature is currently absent from the majority of thermostats available.

HELTUN touch buttons are so sensitive that they react even before you physically touch them, processing the action at a 1-2mm distance. The buttons are:

  • Manual control button to switch your heating on or off manually
  • "Mode" button to quickly change the operating mode of the thermostat (e.g. switch to economy mode or to the fast floor drying mode, etc.)
  • "Time" button that allows you to quickly adjust the temperature for different time of day
  • "Settings" button that allows to modify up to 20 various settings and parameters of the thermostat
  • "+" and "-" buttons for adjusting the temperature

LCD Screen
HELTUN’s large LCD screen shows all the necessary information simultaneously and, unlike many other models, does not require any additional commands to access it. There is instant access to information from all sensors: ambient room temperature, air humidity, data from the external sensor (e.g. floor, decking or roof temperature), current temperature settings, Thermostat’s operational mode, date and time.

Automatic screen brightness control seamlessly adjusts to the ambient light conditions, making it easy to read even in the dark.

Heating modes
COM, ECO, VAC modes constantly maintain the set temperature. The user can easily change the temperature set for each mode. To do this, simply press the "mode" button to select the desired mode, and use the "+" and "-" buttons to set the required temperature. In most thermostats, this data can only be changed via the settings menu, causing a lot of inconvenience, not to mention that in some thermostats these figures are set by the manufacturer and cannot be changed.

The DRY mode switches the thermostat to the rapid heating mode at a higher temperature and, after a certain time (set to default at 20 minutes) switching it back to the previously set mode. This function is mainly used for quick post-wash floor drying.

MAN mode (manual control) is used to switch the heating on and off manually.

TIME mode allows to set a different temperature for Morning, Day, Evening and Night period for each 7 days of the week.

Time Mode
Reduce your power bill by up to 50% and help look after the environment by activating the TIME mode. Adjust home temperature according to your habits by reducing it while you are away from home and increasing in the evenings and early mornings.

On average, people spend about 12-14 hours a day at home. The rest of the time the house is empty and only needs minimum heating. Consider 7/8 hours of sleeping time in the hours spent at home, keeping in mind that the optimal sleeping temperature is considered to be 18 degrees Celsius.

The thermostat can be set individually for morning, day, evening, night. For example, it can be assigned for Monday morning start at 7.00, then day temperature starting at 9.00 (when absent for work etc.), then evening starting at 18:00 (half an hour before occupants return). The night regime then begins at 23.30 (bedtime).

You can have separate temperature settings for all 4 periods. But this is not all; as temperature can be programmed for each day of the week, weekends can be handled differently.

Automatic comfort control
Choose the functioning of temperature control based on floor, ambient or combined readings. The system can be fine-tuned to provide maximum comfort at all times. For example, if ambient temperature is within your set limits but floor temperature drops, the underfloor heating system will be switched on automatically. The system safeguards will not allow the temperatures to rise above or drop below the comfort level.

1) If control is based only on the ambient air sensor, the thermostat will regulate the ambient temperature, regardless of the floor temperature.

2) If control is based only on floor sensor, the thermostat will regulate the floor temperature, regardless of the ambient temperature.

3) If control is based on ambient sensor, but with floor temperature limits, the thermostat will maintain the specified temperature for air, but will not allow the floor temperature to deviate from the specified limits.

4) If control is based on floor sensor, but with ambient limits, the thermostat will maintain the specified floor temperature, but will not allow the ambient temperature to deviate from the specified limits.

Hysteresis defines when the system should switch the heating on or off when temperature changes. For example, if the desired temperature is 25 degrees Celsius and hysteresis value is set to 0.5 degrees, it will switch the heating on when ambient temperature drops to 24.5 degrees Celsius.

The higher your hysteresis value is set, the more energy you can save but at the same time the variations in your room temperature will be higher. The factory default is 0.5 degrees.

Safe & save
HELTUN devices have a special feature to protect the floor from overheating; Under any circumstances, the thermostat will not allow the floor temperature to go above 40C, regardless of the mode, since it can be harmful to the soles of the feet.

In case of a power cut or disconnection from the main power source, internal memory is not erased – once you switch the device back on, all your saved settings will be fully functional.

To prevent children from meddling with your thermostat settings, you can activate the special child-safe mode.

Z-Wave Plus S2 Certified
Connect your HELTUN devices to the Smart Home controlling system using the latest secure Z-Wave plus chip with new advanced Security 2 (S2) framework (AES 256 encryption method for data transfer).

The HELTUN thermostat is compatible with all Z-WAVE certified controllers and devices.

With the Z-Wave controller, you can manage all the functions of the thermostat via a mobile application, including temperature and mode change, viewing accurate energy consumption charts and much more.

Also, up to 10 separate devices can be connected to the thermostat. You can associate with the Heltun thermostat any Z-Wave compatible ON/OFF switcher or other thermostat and control different climate systems in the room, or even connect motion sensors and adjust the change of modes via identification of people and general movement inside the house.
