The VTS HMI HY controller is used to control the Volcano EC hot air blowers, providing smooth speed control and control in heating, cooling and ventilation modes. It also allows you to set a special anti-freeze mode, which protects the heat transfer medium from freezing.

Using the built-in thermostat (or an external temperature sensor that can be connected to select the temperature measurement location), you can set specific operating parameters for the whole week, up to four heating periods per day - a weekly mode that helps automate operation. 

The following operating modes can be set using the controller:

• Heating: supply of warm air;
• Cooling: chilled air supply;
• Ventilation: ventilation or air recirculation;
• Heating combined with ventilation;
• Cooling combined with ventilation.
