Brief Introduction of Volcan

Existing thermostats often have problems effectively interacting with the users. Their function is limited to a programmable key. What is more, the programming capabilities of these devices are limited as well, giving no help to the user for selecting an optimal and standard schedule. Besides, these thermostats lack different programs and working modes, according to the users' need and have no influence on energy saving along with users' ease. Therefore, a comprehensive thermostat, equipped with a simple and powerful user interface, which can assist the users to reform consumption patterns and decrease the costs, is of high account.

Volkan is a smart thermostat, in which designing and enacting different methods such as standard-based programming, welfare scenarios, and energy monitoring along with a new graphic interface, has allowed it to address all the problems of other thermostats. It is equipped with a CPU, connected to a graphic interface, one or several storage sections, one or several temperature sensors, and an output driver network. Based on the input touch command from the user as well as the information coming from the temperature sensor and in accordance with the schedules and routine control of each case by the output driver network, itself of relay type, the CPU controls the heating/cooling facilities along with the air conditioning.

Energy Monitoring Consumption

Monitoring the energy helps you know more about the way of your consumption, which results in being more economical in energy consumption. By means of this program, the information about the energy consumptions are stored as daily and monthly charts in the memory. Moreover, this thermostat is capable of storing and showing the information about the energy consumption of the first year along with the details and general information of the previous ten years.

The information, given to the user about the history of energy consumption, includes the working hours of cooling/heating units along with the time and the number of hours of the day or days of the month, in which the user has managed to save energy. All of these pieces of information are shown to the user with developed graphical signs and symbols. For example the user is informed about the number of hours he has saved energy with a green leaf on the screen and about his saving period, with a green bar. Looking at this green leaf and green bar, the user becomes determined to gradually increase his green hours in the coming day, week, or month. Hence his consumption pattern is reformed in accordance with the standard.

Weekly Programming

The product's program is weekly, having a four-level daily program by default. This program is set in accordance with Energy Star Standards of America, which suggests to the user that instead of excessive use of heating devices in the winter and energy waste, he could choose a milder temperature and use warmer clothing at home.

Welfare Scenarios: 

One of the facilities of this thermostat to decrease the energy consumption and provide welfare is the design of four comprehensive scenarios for different circumstances, which the user face frequently while using the device. Each scenario has its own graphical environment, guiding the user to select and adjust the parameters of each.

Turbo Scenario: The main aim of designing this scenario is to prevent HVAC Equipment from remaining on excessively. In fact when the user feels excessively cold or warm, he may choose this scenario and insert his desired amount of temperature increase or decrease. Consequently, the control unit, after measuring the temperature of the adjustment point and based on the routine control relevant to this scenario, forces the cooling/heating systems for a short time with the highest efficiency so that the desired welfare is provided quickly. Afterwards in order to decrease energy consumption, it automatically prevents the device to remain on wastefully and function excessively. The working time of the thermostat in turbo mode is limited, depending on the size of the considered room or place. It can be set by means of the advanced setting menu.

Sleep Scenario: In average, each human being spends more than one third of each day in sleep; therefore, having a convenient temperature during the sleep is of high account. As we know, human's body temperature descends during the sleep, hence this thermostat with designing and running the sleep scenario will provide an appropriate temperature during the night, that is, the control unit after detecting the user's command concerning the selection of sleep scenario, based on defined routine control for this scenario, increases or decreases the temperature (in accordance with the selection of the device's mode) for one degree after one hour, and another degree after two hours and after eight hours it returns to the normal condition determined by the user. 

Away Scenario: Throughout the world, a great amount of energy and its subsequent cost is wasted for heating and cooling empty houses or spaces. By designing and utilizing an appropriate scenario, one can be economical in terms of consuming this energy and spending this cost. Once Away Scenario is selected by the user, the controller sets the fan speed at the lowest rate possible and the temperature for cooling or heating circumstances, in accordance with the temperature determined within the standard, which results in economical consumption of the energy (for example during the summer the thermostat employs the cooling unit so that the house's temperature will not surpass 29 degrees; similarly during the winter the heating unit does not allow the house from getting colder below 16 degrees). As a result, apart from saving the energy, cooling/heating devices will not remain on more than what ire required and will not suffer from any depreciation.

Off Scenario: One of the concerns of users in cold season, when the temperature drops a lot suddenly (especially in houses and villas, north of the country which are unoccupied for a long time), is the freezing of the environment (such as water pipes) that sometimes impose great costs on the users. One solution for this problem is to design a functional scenario for these circumstances. In case of the user's request for protection against freezing, even if the device is off, the thermostat studies the environment's temperature and if it realizes that it is near freezing temperature, it turns heating facilities on, thus preventing possible damages.

With a electricity shock, the thermostat becomes on to show the situation of the fan or the split duct, environment temperature, adjusted temperature, and function mode. You can work with the device by sliding, clicking, or holding.

* To change the temperature, you only need to move your finger up and down on the slider and change the adjusted temperature from 10 to 35 degrees centigrade. The center of the screen shows the adjusted temperature with an accuracy of 0.5 degree. Furthermore, the environment temperature can be seen and changed with an accuracy of 0.1 degree centigrade around the adjusted temperature. Volkan Thermostat, based on SEDNA Electronics, the Netherlands, shows the adjusted temperature bigger than that of the environment.

In order to go to the menu, click the slider's center, and see and change fan speed, cooling/heating mode, weekly schedule, and energy consumption monitoring. 


Adjust the fan speed or by selecting Auto, minimize energy consumption.

Move between cooling and heating systems.

Volkan has a four-level daily schedule by default, which is designed based on Energy Star Standards, America.

The menu of energy management, in both daily and monthly forms, shows the amount of your consumption.

In setting menu, you can determine the on/off states of the sound, the screen's light intensity, and the date and history of the device. You also can go to Away and Off setting menu, have access to advanced setting, and see the Contact Us page.

In order to turn the thermostat off or change the defined scenarios, hold the slider's center for some moments. Then go up and down the slider and select Turbo, Sleep, Away, or Off scenarios. Selecting the Off Scenario, turns the thermostat off.
