At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

Uponor Vario PLUS actuator NC MT 230V

The Uponor Vario PLUS actuator NC MT 230V is a high-precision electrothermal head designed for the automatic control of return valves on Uponor radiant floor manifolds. This component is essential for transforming a radiant heating system into an intelligent and efficient solution through precise zone management.

Thanks to its compact design and low-consumption technology, this actuator ensures smooth opening and closing of circuits, optimizing thermal comfort and reducing energy expenditure in residential and commercial installations.

Hydronic Efficiency and Advanced Protection

The Uponor Vario PLUS actuator solves thermal regulation issues through a reliable and durable mechanism.

  • Normally Closed (NC) Configuration: The actuator keeps the circuit closed without water flow when it does not receive power, ensuring system safety.

  • IP54 Protection: Certified against dust and water splashes, allowing for installation on manifolds located in humid environments or technical cabinets.

  • Minimum Energy Consumption: With only 1W of power, it allows for continuous operation with a negligible impact on electricity bills.

  • Visual Status Indicator: Allows for quick verification of whether the valve is open or closed, facilitating maintenance and commissioning tasks.

Professional Installation and Compatibility (E-E-A-T)

The Uponor Vario PLUS actuator NC MT 230V stands out for its ease of assembly, reducing installation times for professionals.

  • M30 x 1.5 Thread Connection: Market standard that ensures a firm and lasting attachment to the Uponor Vario PLUS manifold.

  • First-Open Function: Delivered partially open to facilitate initial balancing and system filling before its first electrical activation.

  • Connection Cable Included: Equipped with an optimal length cable for quick connection to the control unit or thermostat.

  • European Certification: Complies with the most demanding safety and quality regulations, guaranteeing its durability in engineering projects.

Technical Specifications

  • Product Reference: 1141678.

  • Operating Voltage: 230V AC.

  • Power Consumption: 1W.

  • Action Type: NC (Normally Closed).

  • Temperature Range: 0 to 60ºC.

  • Closing Force: 100 N.

  • Stroke: 5 mm.

  • Protection Degree: IP54 (Class II).

  • Mechanical Connection: M30 x 1.5 mm.

Frequently Asked Questions (FAQ)

Is it compatible with manifolds from other brands?

Although it uses the standard M30 x 1.5 thread, the Uponor Vario PLUS actuator NC MT 230V has been designed and optimized specifically for Uponor Vario PLUS manifolds. For other brands, we recommend verifying the valve's closing height.

What does "NC" (Normally Closed) mean?

It means that, in the absence of electrical power, the actuator presses the valve downward to prevent water flow. Only when the thermostat demands heat and sends 230V does the actuator retract to open the circuit.

How long does it take to open completely?

As it is a thermal actuator, the process is not instantaneous. It takes approximately 3 to 5 minutes to reach full opening, a time designed to prevent water hammer and noise in the installation.

Are you a professional installer or HVAC company?

We offer specialized technical support and volume pricing for professional projects. If you have questions about the compatibility of this actuator with your current system, contact our technical assistance team by phone or in person.
