Product description

Control your ventilation with our LTV Potentiometer, a straight forward 0-10 V device designed for optimal control of EC fan speed, AC fan speed controllers or valve actuators. This potentiometer empowers you to fine-tune your ventilation system effortlessly, ensuring a comfortable and controlled environment. Operating at a supply voltage of 230 VAC, the LTV potentiometer delivers a variable output signal ranging from 0 to 10 VDC, easily adjustable via its user-friendly rotary knob. This knob features a distinctive off-position, ensuring a seamless transition to zero output in a simple turn. The splash-proof enclosure further enhances its adaptability, allowing for both inset mounting (IP44) and surface mounting (IP54), making it a reliable choice for diverse installation needs.

Experience clarity in control with the integrated green LED indicator, providing a visual cue when the output value surpasses 0 V. The LED comes to life as the rotary knob is turned clockwise, signaling an active state away from the off-position. Conversely, in the off-position, the green LED deactivates, maintaining a clear visual representation of the system's status.

Additional specifications and description

 
The purpose of an HVAC potentiometer
A potentiometer serves the purpose of generating a continuously variable signal to control other devices. The control signal is adjusted based on the position of the rotary knob, commonly used for remotely controlling EC fans, damper actuators, AC fan speed controllers or frequency inverters. This allows for decentralized installation, such as placing the potentiometer in an office room while the fan speed controller is situated in a technical room or electrical cabinet.
The LTV-1-010-NA potentiometer is developed to control fans equipped with an EC motor or to be used as an input device for fan speed controllers with 0 –10 VDC inputs (Sentera’s EVS or MVS series of fan speed controllers or FI-E series of variable frequency drives). 

Standard 230 VAC supply voltage and output signal
Operating with a 230 VAC supply voltage, this potentiometer produces an output voltage ranging from 0 to 10 VDC. The 230 VAC supply voltage is standard in many electrical systems, and the 0 - 10 VDC output range facilitates precise adjustment of associated HVAC equipment. Directly connecting to the mains without a power supply module simplifies the setup, enhancing convenience.

Unrivalled simplicity
Connecting and using the LTV-1-010-NA is simplified in such a way that it is intuitive and does not require special tools or in-depth knowledge.

0-10 VDC control signal 
The 0 - 10 VDC control signal is a prevalent method in the HVAC industry for regulating parameters like EC fan speed or valve positions. Representing a range of desired settings, the 0 - 10 VDC signal corresponds to modulation from 0 % to 100 % of the parameter. A 0 V signal signifies the minimum setting, while a 10 V signal denotes the maximum, providing versatile control possibilities.

OFF position
The rotary knob of the LTV-1-010-NA has an OFF position, i.e. when the rotary knob is turned completely counterclockwise, the control signal will be disabled. When the rotary knob is turned clockwise, it clicks out of the OFF position. The control signal will immediately go to its low limit level. In case an EC fan is connected to the potentiometer, it will start and accelerate towards low speed. 
  
Green LED operating indicator
The green LED operating indicator lights up when the rotary knob is turned clockwise, i.e. when not in the OFF position. In OFF position the green LED is deactivated.

Enclosure
In order to guarantee the quality of its enclosures, Sentera designs and manufactures them in its own factory – Sentera Plastics. The  enclosure of the LTV-1-010-NA is a wall-mounted housing made of durable ASA plastic in a cream color (RAL 9010). The material offers UV resistance and protection against dust, water splashes and impacts. The design supports two-in-one installation on walls or panels, accommodating both inset and surface mounting options. With IP44 for inset mounting and IP54 for surface mounting, the enclosure reliably shields internal components from environmental elements. 
The design aligns with standard European wall boxes for seamless inset mounting, and its overall solidity suits various wall types. The combination of material and design features enhances durability and suitability for diverse HVAC environments. Cleaning is simple, requiring only a damp cloth, contributing to maintenance convenience.

Geras potenciometras 0-10V išėjimu, o dar ta LED indikacija, tai man labai patiko, nes matosi kada potenciometras veikia.
