Frequently asked questions

  • What is the difference between this controller and a standard room thermostat? A controller generally offers more advanced functions - controlling several heating circuits at once, weather-compensated operation based on outdoor temperature, and possibly also control of hot water heating and remote control via the internet/app, unlike a simple thermostat, which usually handles only one zone.
  • Is this controller compatible with my boiler? Check the exact type designation of your boiler/heat source against the compatibility stated in the name and description of this product - controllers from original brands (e.g. Vitotrol for Viessmann) are usually intended only for that particular boiler brand.
  • Must the installation be carried out by a professional? Yes, connecting the controller to the boiler/heating system and setting it up should be carried out by a service technician, who will also verify the correct functioning of the entire system.

Zdravím, plánujeme si do bytového domu nainstalovat tento regulátor a zajímalo by nás, jestli umí ovládat i samotný kotel nebo jen ten směšovací ventil? A funguje to s tím internetovým modulem, abychom mohli teplotu měnit z mobilu?
A Avatar of author 24/10/2026 20:01
Ahoj, regulátor přímo ovládá směšovací ventil a čerpadlo, ale pro zapnutí zdroje tepla (kotle) potřebuješ připojit beznapěťový výstup, který je součástí vybavení. Pokud chceš vzdálené ovládání přes internet, stačí dokoupit příslušný modul EU-505 nebo WiFi RS, které jsou kompatibilní s touto řadou.

Du coup , je peux garder le circulateur pour les radiateurs, le circulateur plancher chauffant, vanne 3 voie plancher chauffant et sonde de température tuyau plancher chauffant . Et je branche tt sur le nouveau boîtier? Il y a aussi le thermostat déporté? Envoyé de mon iPhone Le 23 oct. 2026 à 15:12, Roman Krajčí a écrit :  Bonjour, Merci pour les photos. Je vois une pompe Wilo Yonos PARA RS15/6, une vanne mélangeuse 3 voies avec son servomoteur et un boîtier de régulation Honeywell fixé à côté. La pompe et la vanne peuvent rester en place. Seul le boîtier Honeywell est à remplacer. Pour le remplacer, je vous conseille un régulateur TECH EU-i-1. Il commande un servomoteur de vanne mélangeuse et la pompe du circuit. Il régule la température de départ à une valeur fixe ou en fonction de la température extérieure. Il peut être couplé à un thermostat d'ambiance. Il y a deux versions : 1. Version avec une sortie supplémentaire pour la circulation d'eau chaude sanitaire, que vous n'utiliserez pas forcément : https://www.atriashop.fr/regulateur-chauffage-tech-eu-i-1-cwu-pour-1-vanne-et-circuit-eau-chaude/ 2. Version simple, pour un seul circuit avec vanne mélangeuse : https://www.atriashop.fr/tech-eu-i-1-regulator-pre-vykurovacie-systemy--pre-obsluhu-1-pohonu-ventilu-2/ Pour le pilotage par téléphone, le régulateur seul ne suffit pas. Il faut y ajouter le module Internet TECH EU-505, qui permet de commander et de suivre l'installation depuis l'application eModul du fabricant : https://www.atriashop.fr/module-internet-tech-eu-505/ Ce régulateur est conçu pour un servomoteur de vanne 230 V. Avant de commander, vérifiez donc sur l'étiquette de votre servomoteur qu'il fonctionne bien en 230 V. Sur la photo, je ne peux pas le lire avec certitude.

Bonjour, Oui, vous pouvez garder le circulateur du plancher chauffant et la vanne 3 voies avec son servomoteur. Le régulateur TECH EU-i-1 pilote une seule vanne mélangeuse et la pompe de ce circuit. Vous branchez donc sur le nouveau boîtier : - le circulateur du plancher chauffant, - le servomoteur de la vanne 3 voies. Une condition : le servomoteur doit fonctionner en 230 V avec commande 3 points (ouverture/fermeture). Vérifiez-le sur son étiquette. S'il est en 24 V, il ne conviendra pas à ce régulateur. La sonde de température du tuyau de plancher chauffant : le régulateur est livré avec ses propres sondes (départ après la vanne, retour, chaudière, extérieure). Je vous conseille d'utiliser la sonde de départ fournie, car je ne peux pas garantir que l'ancienne sonde Honeywell soit compatible. Le circulateur des radiateurs : le TECH EU-i-1 n'a qu'une seule sortie pompe, destinée au circuit de la vanne mélangeuse. Il ne pilote donc pas le circulateur des radiateurs. Ce circulateur doit rester commandé comme aujourd'hui (par la chaudière ou son propre thermostat), ou être raccordé séparément. Pour le thermostat d'ambiance déporté, le régulateur est compatible avec les thermostats filaires TECH à contact simple. Le thermostat peut baisser la température de départ de la vanne ou la fermer. Deux modèles conviennent : 1. Thermostat filaire simple TECH EU-294 v1 : https://www.atriashop.fr/regulateur-mural-filaire-tech-eu-294-v1/ 2. Thermostat filaire hebdomadaire programmable TECH EU-292 v3 : https://www.atriashop.fr/regulateur-de-chauffage-hebdomadaire-filaire-tech-eu-292-v3-blanc/ Le pilotage par téléphone se fait avec le module Internet TECH EU-505 et l'application eModul, comme indiqué dans mon message précédent.

Mám doma kotol a chcel by som nejako automaticky ohriať vodu v bojleri, keď treba, ale neviem či toto zariadenie na to stačí alebo či potrebujem niečo iné navyše?
A Avatar of author 29/08/2026 11:13
Tento regulátor EU-i-1 CWU je presne na takýto účel – zvládne ovládať jeden ventil (servopohon) a zároveň riadi aj ohrev teplej úžitkovej vody cez čerpadlo. Takže na základné zapojenie s bojlerom by vám mal stačiť. Ak si nie ste istý konkrétnym zapojením, pokojne nám napíšte alebo zavolajte, radi poradíme.

Company

The company TECH Controllers was founded in 2004. Since its inception, it has been developing dynamically and soon became a leader in the production of electronic devices for heating, whether it is solid fuel or other energy sources. At present, the total area of our company exceeds 7,500 m², where several hundred employees work. Our specialized controls for various types of equipment are sold throughout Poland and in another 19 European countries.

Company headquarters

Wide range of modern products

Our company produces controls for all types of heating equipment with a focus on maximum use of their potential. Thanks to precise zonal heating, the ideal temperature for both health and comfort is maintained in all rooms of the building. Our offer includes controls for:

  • Radiator heating
  • Floor heating
  • Heating systems
  • Room controls
  • Other (including controls for renewable energy sources, stoves, boilers and special controls)

All our heating controls are designed both visually and functionally with a focus on comfort and savings for the user. They include certificates of conformity with the European directive, which confirm that the products meet the requirements of harmonized standards under the Low Voltage Directive 2006/95/EC.

Advanced solutions in the control development process

Production hall

The production of controls in our plant is a fully automated process that takes place on two production lines. We regularly deliver new features to existing device models, develop new models that enrich the current offer. In each phase of control production, we perform special test checks that ensure the long life of the devices and high comfort for the user. Each programmer works with a tester who checks the correct operation and all details in the device logic. Part of the production process is our own laboratory, where we check the devices at each stage. In a special climate chamber, we check the correct operation of the controls under various temperature conditions.

Tools dedicated to the user

Programmers of our company have developed a special eModul application that allows remote control of the operation of both the heating device and the temperature in the rooms using a mobile phone or tablet. This makes it possible to save even more on heating while you are away from home, while still keeping the operating parameters of the heating system under control, whether you are at work, on the road or shopping.

Heating control via the internet

To improve communication with the customer, we have a modern web tool - a configurator, which was created for everyone who wants to independently assess which devices they will need for heating control. The system configurator allows you to quickly and easily select control system components according to your needs, preferred installation and type of building. You can prepare your own set taking into account the number of rooms and whether they have radiators or floor heating.

Installer Academy and presentation vehicle

Installer Academy

We are very happy to share our knowledge and exchange experience, so for many years we have been organizing free training for installers, during which we present our devices, explain their working principle, operation and installation. The Installer Academy is organized periodically in RUŽOMBEROK and TRNAVA, as well as according to customer requests in other cities.

A great opportunity to present the latest products is our presence with a special exhibition vehicle, which we travel according to the needs of our business partners. The car is equipped with the latest and most frequently purchased device models for heating control.
