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.

ESBE ZRS220 motorised 2-way zone valve for heating and cooling

The ESBE ZRS220 opens or closes the water flow to one zone on a 2-point 230 V signal and spring-closes when power is removed. At Q-Tech we fit and wire it in the pre-assembled plant room, which reaches your site already tested.

What is the ESBE ZRS220?

The ESBE ZRS220 is a 2-way zone valve for heating and cooling that spring-closes in 5 seconds, according to ESBE. A side lever lets you operate it by hand. The actuator is held by a screw and can be removed even with the system under pressure.

What problem does it solve?

In a home with several zones, each thermostat must be able to cut the water to its zone without stopping the rest of the system. The ZRS220 receives the signal from its thermostat and opens or closes the flow to that zone.

If power is lost, the spring closes the valve and the zone stops receiving water. ESBE recommends this actuator for on-off operation, not for flow control.

  • Closed circuits only, for heating and cooling, according to ESBE.
  • Maximum differential pressure of 200 kPa on DN 15 and 80 kPa on DN 32.
  • With more than 20% glycol, ESBE asks you to check the pump data.
  • It needs a 2-point 230 V signal from a thermostat or controller; it does not control flow.
  • ESBE offers the ZRS921 replacement actuator (47120100), which is not on this page.

Frequently asked questions

Which model do I need?

The one that matches your pipe size: from DN 15 (G ½) to DN 32 (G 1¼). Tell us about your installation and we will tell you the model.

What is the difference from the ZRS230?

The ZRS220 is a 2-way valve that opens or closes one zone. The ZRS230 is a 3-way valve that sends water to one of two circuits.

Can it be opened without power?

Yes, by hand, with the lever on the side of the actuator, according to ESBE.

Can the actuator be changed without draining the system?

Yes. ESBE states that the actuator can be removed with the system under pressure; the spare part is the ZRS921.

Can I install it myself?

It is not advisable: a professional should install and wire it, following ESBE's instructions. Q-Tech delivers it fitted in the plant room or installs it with an Expert Technician.

What is the delivery time?

We have it in stock in Málaga and dispatch it as soon as we confirm your order.

Q-Tech installation and support

With the pre-assembled plant room, the ZRS220 arrives fitted in its zone, wired to the thermostat and tested in our workshop. You can book workshop pre-assembly, an on-site hourly Expert Technician to install it or a technical call to choose the size. See also our valves and accessories or message us on WhatsApp.
