Datasheet
Potentiometer | no OFF position
Product description
MTVN1-010-NA is a potentiometer for remote control of various HVAC equipment. It operates on a 230 VAC supply voltage and provides a 0—10 VDC output signal.
The rotary knob offers continuous and precise control of devices like EC fans, damper actuators, and frequency inverters. The device intentionally lacks an OFF position, ensuring the control signal never drops to 0 V. This is ideal for applications requiring continuous minimum air supply.
It supports both inset (IP44) and surface mounting (IP54).
Additional specifications and description
What is the Purpose of an HVAC Potentiometer?
A potentiometer generates a continuously variable signal to control other devices. This control signal increases or decreases according to the position of the rotary knob. The control signal is typically used to remotely control EC fans or damper actuators. It can also remotely control AC fan speed controllers (EVS or MVS series) or frequency inverters (FI-E series). For example, the potentiometer can be installed in a study while the fan speed controller is located in a technical room or an electrical cabinet.
What is the Supply Voltage?
This potentiometer operates with a supply voltage of 230 VAC and produces an output voltage ranging from 0 to 10 VDC. The 230 VAC supply voltage is common in many electrical systems, and the 0—10 VDC output range allows for precise adjustment of the associated HVAC equipment. MTVN1-010-NA can be directly connected to the mains without the need for a power supply module.
A 0—10 VDC control signal is the most common method used in the HVAC industry for controlling various parameters, such as EC fan speed, valve positions or other components in electronic systems. The 0—10 VDC control signal corresponds to a range of desired settings. For example, if you have a system that requires modulation or adjustment, the 0—10 VDC control signal can be interpreted to represent a range from 0 % to 100 % of the desired parameter. A 0 V signal might indicate the minimum setting, while a 10 V signal could represent the maximum setting.
Why There is no OFF Position in This Potentiometer?
The absence of an OFF position in the potentiometer implies that even when the rotary knob is at its minimum position (turned fully anticlockwise), the control signal will not reach 0 VDC but will maintain a minimum value that approaches 0 VDC. In situations where it is technically or legally necessary to ensure a minimum air supply at all times, this design feature prevents a complete shutdown of the associated equipment.
This configuration is intentional, as it ensures that there is always a minimum level of control or operation, addressing the specific requirements or constraints of certain applications. It is essential to consider such design aspects to comply with regulations or meet the operational needs of HVAC systems in various scenarios.
What Makes the Enclosure Reliable?
The potentiometer features a wall-mounted housing constructed from durable white ASA plastic. The choice of material ensures UV resistance and offers protection against dust, water splashes and impacts. The design allows for versatile installation on any type of wall or panel as the enclosure accommodates both inset and surface mounting options, providing flexibility in installation. The protection class is IP44 for inset mounting and IP54 for surface mounting, attesting to its reliability in safeguarding the internal components against environmental elements.
For inset mounting, the enclosure design aligns with standard European wall boxes, ensuring a seamless fit. The overall solidity of the enclosure makes it suitable for mounting in various types of walls.
This combination of material and design features contributes to the potentiometer durability and suitability for various environments within the HVAC sector. Cleaning is a straightforward process, requiring only a damp cloth, adding to the convenience of maintenance.
