YOUR COMFORTS MATTERS.

When considering thermal comfort, what aspects are the most important? Is it general room temperature? Heating or cooling temperature? Conditioning or ventilation speed? Or may be something else? Whatever the need, HELTUN guarantees to take care of it.

Take control

Five channel relays, 5 Amp load each, with two independent dry contact inputs for fans and valves control. 

Elegant Design

The Fan Coil Thermostat is available in 30 combinations to integrate seamlessly with your interior design. Five frames (silver, chrome, gloss black, matte black, & white), and six glass colours (white, black, yellow, green, red and blue) let you match any environment, style, or taste. Designed to be powerful, efficient and stylish, at 9 mm thick the Fan Coil Thermostat is ‘impossibly thin’ and good-looking on your wall.

Internal sensors

In addition to the temperature control sensor, the HELTUN Fan Coil Thermostat also features built-in humidity and ambient light sensors which can be monitored by a Z-Wave controller and used to trigger home automation scenes. The frequency (reporting time) of data updates from sensors can be individually adjusted to meet the needs of your smart home system.

Multiple sensors help save energy

When electronics are operating they generate heat. As a result, some thermostats measure ambient temperature with only 1.5-2.0° Celsius precision. The HELTUN Fan Coil Thermostat design incorporates four additional internal sensors and compensating software to calculate ambient temperature with ten times better precision: 0.2-0.3° C. This helps make you more comfortable while saving energy.

Inputs & outputs

The main power input can be either 85-265VAC 50Hz/60Hz, or 24-48VDC. There are five relay outputs each with a maximum 5 Amp load. There are also two independent inputs for relay channels which allow control of systems with different power sources for fan speed and for heating/cooling valves. Input 1 with the required power source is for fan speed and is used for relay channels 1, 2 and 3, which can carry a maximum 15 Amp load. Input 2 with the required power source is for heating and cooling and is used for relay channels 4 and 5, which can carry a maximum 10 Amp load.

Know how much energy you use

The HELTUN built-in Power Consumption System precisely monitors how much energy you used during any particular day, week, or month. Does your current thermostat do that? Just specify the consumption of the load in watts for each relay channel and the thermostat logic will calculate total consumption relative to the time since the output was in the ‘ON’ state We have also designed the circuitry so it draws almost zero watts to power itself when in standby mode. This saves you energy and money even if your home is equipped with many HELTUN products.

Controls

The HELTUN Fan Coil Thermostat has six capacitive-touch buttons which react to even the lightest touch to access the following functions:

  • “SPEED” button to control the fan speed (cooling, heating or ventilation power) with three levels (Low, Medium, High) or in Auto mode.
  • "Mode" button to  switch between modes (e.g. Comfort, Economy, etc.).
  • "Time" button that allows you to quickly adjust the temperature for different times of the day.
  • “Climate” button lets you select climate mode: heating only, cooling only, heating and cooling, or ventilation only. Hold “Climate” to open the settings menu for more than 30 different parameters adjustments.
  • "+" and "-" buttons for adjusting the temperature

LCD Screen

The large LCD display shows all necessary information at-a-glance without forcing you to activate or manipulate any controls. You have instant access to all sensor and setting information: room temperature, humidity, set point, thermostat mode, climate mode, fan speed plus date and time. Display brightness can be adjusted manually to 15 different brightness levels, or automatically using the ambient light sensor. This allows you to read the display easily even on bright sunny days, and will not overpower your eyes at night.

Operating modes

COM and ECO modes maintain the temperature you set which can be easily adjusted by selecting the mode desired and pressing the “+” or “–” control.

TIME mode allows you to set a different temperature for Morning, Day, Evening, and Night periods for each day of the week.

Climate Modes

In Heating & Cooling mode the thermostat will constantly maintain the desired temperature. If room temperature is higher than the Set Temperature the Fan Coil thermostat will start cooling the house. If room temperature drops below the Set Temperature the thermostat will start heating the house.

In Heating only mode the Fan Coil thermostat will heat the house if room temperature is lower than the Set Temperature, and will go into IDLE state if room temperature is higher than the set point.

In Cooling only mode the Fan Coil thermostat will cool the house if room temperature is higher than the Set Temperature, and will go to IDLE state if the room temperature is lower than the set point.

In Ventilation mode the Fan Coil thermostat will only operate the fan to ventilate the house.

Time Mode

You could reduce your power bill by up to 50% and help the environment by activating TIME mode. Adjust your home comfort level according to your family’s habits by reducing the temperature while everyone is away, and boosting it for evenings and early mornings.

People spend about 12-14 hours a day at home on average. The rest of the time an empty house needs minimal heating. And considering that much of the time at home your family is sleeping, it can make a huge difference setting your home’s comfort level to 18° Celsius overnight which is considered to be the optimal sleeping temperature.

Using TIME mode, you can set different temperatures for Morning, Day, Evening, or Night. For example: ‘Morning’ mode might start at 7:00 @ 23°C and then shift to ‘Day’ at 8:30 @ 17°C when everyone is off to work and school. ‘Evening’ mode might start at 16:00 @ 22°C and then shift to ‘Night’ at 23:00 @ 18°C. Setting temperatures for these four periods can save a lot on your power bill plus you can adjust for weekdays versus weekend days.

Fan Speed

Fan Speed (heating, cooling, or ventilation) can be controlled manually or in Auto mode. There are four speed levels: Off, Low, Medium, High, Auto Medium, Auto High. In Auto mode the Fan Coil thermostat logic automatically selects the speed level depending on the difference between the temperature set point and ambient room.

If the difference is less than 1.0C the thermostat will select Low speed level.
If the difference is in range 1.0C – 2.0C the thermostat will select Medium speed level.
If the difference is more than 2.0C the thermostat will select High speed level.

When room temperature equals set point temperature, the thermostat enters IDLE state (fan off).

Hysteresis

Hysteresis is a technical term which defines when a heating or cooling system should turn on or off when the temperature changes. For example, if the desired temperature is 25°C and the internal hysteresis value is set to 0.5°C, the system will switch OFF the heating when the temperature reaches 25°C and switch it back ON when room the temperature drops to 24.5°C. The higher your hysteresis value is set, the more energy you can save but the variations in room temperature will be greater. The factory default hysteresis value is 0.5°C.

Safe & save

In case of a power outage, the Heating Thermostat’s internal memory is saved and will not be erased. Once the thermostat comes back online all your settings will be fully functional. To prevent your kids from changing any thermostat settings, you can activate the ‘child-safe’ mode which locks the control buttons and prevents any accidental changes.

Easy to install

HELTUN thermostats can be easily installed into any standard electrical junction box (square or round) in just minutes. Installation must only be performed by someone trained in handling high voltage electrical systems.
