Comfort and savings with Heltun

Considering thermal comfort, what aspects are the most important? Is it the general temperature of the room? Soil temperature? Climate control? Or ... maybe something else? Whatever the need, HELTUN ensures you take care of yourself.


Powerful, efficient and well designed, HELTUN is the slimmest and most elegant thermostat on the market. Featuring a crystal clear glass panel, its short-circuited, fire-resistant recycled plastic casing is only 9mm thick.

Premium design

HELTUN fits perfectly into your interior design and is available in 24 combinations: 4 frame colors (silver, chrome, white and black) and 6 types of glass (white, black, yellow, green, red, blue). You can choose any style that suits your taste.

Internal sensors

In addition to the temperature control sensors, the HELTUN thermostat also incorporates humidity and light sensors.

Additional sensors that help you save energy

When an electronic device performs its function, a certain amount of heat is generated. As a result, the room temperature is usually reported incorrectly with an accuracy of 1.5-2.0 degrees Celsius. HELTUN engineers have added two additional internal sensors that take into account the excess heat generated by the device itself, while special compensation software calculates the ambient temperature with an incredible precision of 0.2 to 0.3 degrees Celsius.

Heltun Thermostat Z-Wave


You can connect an NTC temperature sensor to the thermostat (a 3m long 3.5mm diameter NTC sensor is included in the box) or use your existing sensor to monitor floor and ceiling temperatures. This sensor can be installed under the floor or on the ceiling, allowing you to accurately measure the temperature of your chosen surface.

It is fully compatible with third-party NTC sensors, so there is no need to replace the existing sensors on your old thermostat when you upgrade to HELTUN.

You can also control the HELTUN thermostat by connecting it to an external system, for example by connecting it to the home alarm system, which will automatically lower the room temperature when the house is empty.

Z-Wave Heltun Thermostat

Know your energy consumption

With the energy consumption system built into the HELTUN thermostat, you can precisely control the amount of energy used for a particular day, week or month. This feature is currently absent from most available thermostats.

The HELTUN thermostat's touch buttons are so sensitive that they react even before you physically touch them, treating the action at a distance of 1 to 2 mm. The buttons are:

Manual control button to manually turn your heater on or off
"Mode" button to quickly change the thermostat's operating mode (eg switch to economy mode or quick-drying floor mode, etc.)
"Time" button that allows you to quickly adjust the temperature for different times of the day
"Settings" button that allows you to modify up to 20 different settings and parameters of the thermostat
Keys "+" and "-" to adjust the temperature
LCD screen
The HELTUN thermostat'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: room temperature, air humidity, data from external sensors (eg floor or ceiling temperature), current temperature settings, Thermostat operating mode, date and time.

Automatic display brightness control adapts perfectly to ambient light conditions, making it easy to read even in the dark.

Heating modes
COM, ECO, VAC modes keep the set temperature constantly. The user can easily change the set temperature 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 through the settings menu, causing a lot of disturbance, not to mention that in some thermostats these numbers are set by the manufacturer and cannot be changed.

DRY mode switches the thermostat to rapid heating mode at a higher temperature and after a certain time (default setting 20 minutes), replaces it with the previously set mode. This function is mainly used for quick drying of the floor after washing.

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

TIME mode allows you to set a different temperature for the morning, day, afternoon and night periods for every 7 days of the week.

TIME mode
Reduce your energy bill by up to 50% and help protect the environment by activating TIME mode. Adjust the temperature in the home according to your habits, lower it while you are away from home, and increase it at night and early in the morning.

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

The thermostat can be individually set for morning, day, afternoon and night. For example, it can be configured to work on Monday morning from 7:00 a.m., then the temperature of the day from 9:00 a.m. (in absence for work, etc.), and the afternoon from 18 : 00 (half an hour before). The arrival of the occupants). The evening program begins at 11:30 p.m. (bedtime).

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

Automatic comfort control

Choose temperature control operation from floor, room, or combined readings. The system can be adjusted to provide maximum comfort at all times. For example, if the room temperature is within the set limits, the floor temperature drops, the underfloor heating system will be activated automatically. System security will not allow temperatures to rise or fall below the comfort level.

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

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

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

4) If the control is based on the floor sensor, but within the 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 turn the heater on or off when the temperature changes. For example, if the desired temperature is 25 degrees Celsius and the hysteresis value is set to 0.5 degrees, the heat will be activated when the ambient temperature drops to 24.5 degrees Celsius.

The higher the hysteresis value, the more energy you save, but at the same time the ambient temperature variations will be higher. The default is 0.5 degrees.

Secure and protect
HELTUN devices have a special feature to protect the floor against overheating; In no case does the thermostat allow the floor temperature to exceed 40 ° C, regardless of the mode, as it can damage the soles of the feet.

If the main power supply is cut off or disconnected, the internal memory is not cleared. Once you have reactivated the device, all the saved settings will be fully functional.

To prevent children from interfering with your thermostat settings, you can enable child protection mode.

Z-Wave Plus S2 Certificate
Connect your HELTUN devices to the home control system using the latest Z-Wave Plus secure chip with the new security framework 2 (S2) (AES 256 encryption method for data transfer).

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

With the Z-Wave controller, you can manage all the thermostat's functions through a mobile app, including changing temperature and mode, viewing accurate graphs of power consumption, and more.

Additionally, up to 10 separate devices can be connected to the thermostat. You can pair the Heltun thermostat with any Z-Wave compatible on / off switch or other thermostat and control different climate systems in the room, or even connect motion sensors and adjust the mode change through identifying people and the general movement inside the house
