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.

What is the Wilo Atmos PICO?

The Wilo Atmos PICO is a Wilo circulation pump for heating and air conditioning that consumes from 4 W with electronic control. Its synchronous EC motor adjusts the speed to maintain the selected differential pressure. It is mounted on the circuit piping with a threaded connection.

Wilo Atmos PICO control modes

  • Variable differential pressure (Δp-v), with three preset curves.
  • Constant differential pressure (Δp-c), with three preset curves.
  • Constant speed, with three fixed speeds.
  • LED indicators for the selected mode and curve; the LED lights up green during normal operation and warns in case of a fault.
  • Motor protection, automatic unblocking, and high starting torque, according to Wilo.
  • Electrical connection with the Wilo connector, particle filter, and wrench seat in the pump body.

What problem does it solve?

When a circulation pump fails, you must match the thread, port spacing, and head. If they do not match the old pump, the piping must be modified. If the pump is underpowered or improperly adjusted, radiators remain cold or consumption increases unnecessarily.

The Wilo Atmos PICO reduces that risk with three standard connection sizes, three control modes, and an adjustment made with a single button. The LED confirms that the pump is working correctly after the replacement.

Frequently asked questions

Which model do I need?

The one that matches your current pump in three data points. The first number is the connection diameter: 15 is G 1, 25 is G 1½ and 30 is G 2. Then comes the head range in meters (1-6 or 1-8) and, finally, the port spacing in millimeters.

What control modes does it have?

Three: variable differential pressure, constant differential pressure and constant speed. Each mode has three curves or speeds, and all are selected with the green button.

Is it suitable for domestic hot water?

It is not the use Wilo recommends: the Wilo Atmos PICO is designed for heating and air conditioning. For DHW, see the Wilo Star-Z NOVA range.

What is included in the box?

According to Wilo, the pump, Wilo connector, gaskets, and installation and operation instructions. Fittings are sold separately.

What is the delivery time?

Shipping on request: we will confirm the timeframe before preparing your order.

Q-Tech installation and support

In a new build, the Wilo Atmos PICO can arrive integrated in a pre-assembled and tested technical room. The Q-Tech team installs it, parametrizes it, and performs the safety and operation tests in the warehouse. On site, only the final connection remains, which is done by the site installer or Q-Tech, for one day depending on the type and size of the room. Learn about the process in Advanced Pre-Assembly and in the Warehouse Pre-assembly service.

If the installation was done by another company, or if it is a replacement of an existing pump, we start with a verification visit by the Expert Technician on-site by the day. Outside the province of Málaga, that visit is hired as an on-site day. If you are unsure between models, book a Technical Call or write to us via WhatsApp. See more circulation pumps or our contact page.
