When Comfort Is Important

The ‘Impossibly Smart’ and ‘Impossibly Thin’ HE-HTO1 Heating Thermostat is made to provide sensors for both ambient and radiant floor heating systems in order to maintain constant room and floor temperatures. It manages boilers, electric underfloor heating, convection or electric fireplaces, radiators, and other electric heating systems. Your energy use is precisely tracked by the built-in power consumption system for any given day, week, or month.

Further Sensors

A specific amount of heat is produced when electronic equipment operates. Because of this, the stated ambient temperature frequently has a precision of just 1.5–2.0 degrees Celsius, which is inaccurate. Two additional internal sensors that HELTUN engineers added take into account extra heat produced by the device itself, and a specialized compensatory program determines the ambient temperature with an astounding 0.2–0.3 degrees Celsius accuracy.

Outputs & Inputs

You can use your existing sensor to regulate floor/roof temperatures or connect an NTC temperature sensor to the HELTUN thermostat (a 3m long and 3.5mm thick NTC sensor is provided in the box). You may precisely measure the selected surface temperature by installing this sensor under the floorboard, on the roof, or under the decking. When upgrading to HELTUN, existing sensors from your old thermostat do not need to be replaced because it is entirely compatible with NTC sensors from other manufacturers. You can also utilize an external system to operate the HELTUN thermostat, such as an alarm system, to automatically lower the interior temperature while the house is unoccupied.

The touch buttons on HELTUN thermostats are so sensitive that they respond even before you actually touch them, processing the action at a distance of just 1-2mm. The buttons are manual control buttons that allow you to manually turn on or off your heater. To easily switch the thermostat’s working mode, press the “Mode” button (for example, to the fast floor drying or economic modes). You may instantly change the temperature during different times of day by using the “Time” button. The “Settings” button on the thermostat lets you change up to 30 different settings and parameters. “+ and* buttons for adjusting the temperature.


The huge LCD screen on the HELTUN thermostat displays all the required data simultaneously and doesn’t require any additional commands to access it. All sensor data, including ambient room temperature, air humidity, information from an external sensor (such as a floor, deck, or roof temperature), current temperature settings, and the thermostat’s operational mode, date, and time, are instantly accessible. Even in low light, reading is still possible thanks to automatic screen brightness management that easily adapts to the lighting environment.Heltun HE-HT01-WW -Heating -Thermostat -fig (3)

Running Modes

The set temperature is continuously maintained in COM, ECO, and VAC modes. The temperature that is set for each mode can easily be changed by the user. Simply push the “Mode button to choose the desired mode, and then use the “+ and “- buttons to adjust the temperature as needed. Most thermostats only allow changes to be made through the settings menu, which is rather inconvenient. Additionally, some thermostats have these values pre-programmed by the manufacturer and do not allow changes. In the DRY mode, the thermostat changes from the pre-set mode to the fast heating mode at a higher temperature after a predetermined amount of time. The primary purpose of this feature is speedy post-wash floor drying. The heating is manually turned on and off using the MAN mode (manual control). For each of the seven days of the week, the TIME mode enables you to choose a distinct temperature for Morning, Day, Evening, and Night.

Date Mode

By turning on the TIME mode, you can cut your energy costs by up to 50% while also protecting the environment. Reduce the temperature in your home while you are away and raise it in the nights and early mornings to suit your routine. People spend 12 to 14 hours a day at home on average. The house is uninhabited for the majority of the day and only minimal heating is required. Taking into account that the ideal sleeping temperature is thought to be 18 degrees Celsius, take into account 7 or 8 hours of sleep. Each of the four temperature settings—morning, day, evening, and night—can be customized. For instance, Monday morning starts at 7:00, followed by day temperature starting at 9.00 (while absent for work, etc.), and evening start at 18:00 (half an hour before inhabitants return) are all possible options. The evening routine then starts at 23.30 (time for bed). For each of the four times, you can set a different temperature. Furthermore, since the temperature might be set differently on the weekends depending on the day of the week, this is not all.

Automatic Comfort

Control Choose the functioning of temperature control based on floor, ambient, or combined readings. The HELTUN Z-Wave thermostat can be fine-tuned to provide maximum comfort at all times. For example, if the ambient temperature is within your set limits but the 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.

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

The HELTUN Z-Wave thermostat has 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.Heltun HE-HT01-WW -Heating -Thermostat -fig (5)
