Potentiometer Vr Ec (0-10V) 1-4-0101-0453

Airflow regulation for heaters and air curtains

The VR EC (0-10V) potentiometer is a small device designed for manual control of fan speed in heaters and air curtains equipped with EC motors. It enables smooth adjustment of airflow, which translates to precise adjustment of heating power to current needs. This is particularly important in applications where energy efficiency and thermal comfort are required.

Application and functionality

The device is universal and compatible with VOLCANO VR Mini, VR1, VR2, VR3 and VR-D heaters, as well as WING EC curtain heaters. One potentiometer can handle up to four heaters simultaneously, simplifying the control system and reducing installation costs. The 0-10V control signal allows for precise adjustment of the device's performance to the conditions in the room. Surface mounting simplifies installation, and the ABS housing provides durability and resistance to damage.

Technical specifications and safety

The potentiometer is powered by 230V AC (±10% / 50Hz), and its permissible load is up to 2mA. It has a protection class of IP30, which means protection against touching with a finger and against the ingress of solid objects larger than 2.5 mm. Operation is performed using the potentiometer knob. It is important to remember to close the housing during use due to the mains voltage supply – opening is only possible with tools. The device has certificates of conformity with applicable safety standards.

For installers:

• Simple surface mounting – minimizes installation time.
• Possibility of controlling up to four heaters with one potentiometer – reduces cabling and control costs.
• 0-10V signal – a standard control signal ensuring compatibility with most modern heating systems.
• Durable ABS housing – ensures long-term reliability even in harsh working conditions.

For end users:

• Smooth airflow regulation – allows for precise temperature adjustment to individual preferences.
• Intuitive operation – easy control with the potentiometer knob.
• Energy saving – possibility of reducing energy consumption by adjusting the heating power to current needs.
• Aesthetic appearance – discreet design to suit any interior.
