Installation Controller - Αντιστάθμιση TECH
Με τον όρο αντιστάθμιση, στις εγκαταστάσεις κεντρικής θέρμανσης με νερό ως μέσο μεταφοράς της θερμότητας, εννοούμε τη λειτουργία ρύθμισης της θερμοκρασίας προσαγωγής του θερμού νερού ανάλογα με τη θερμοκρασία περιβάλλοντος.
Ιδιαίτερα κατά τους φθινοπωρινούς και ανοιξιάτικους μήνες, και ενώ λειτουργεί η κεντρική θέρμανση του κτιρίου, παρατηρείται συχνά περιοδική αύξηση ή μείωση της θερμοκρασίας χώρου η οποία υπερβαίνει σημαντικά τα όρια άνεσης των ανθρώπων που ζουν ή εργάζονται σε αυτόν. Το φαινόμενο αυτό οφείλεται στην έλλειψη αντιστάθμισης στηνεγκατάσταση θέρμανσης και επιφέρει έλλειψη άνεσης και σπατάλη χρημάτων.
Η αιτία βρίσκεται στο ότι η ισχύς των σωμάτων που τοποθετούνται σε ένα χώρο υπολογίζεται ώστε να μπορούν να ανταποκριθούν στις ανάγκες θέρμανσης, όταν στο περιβάλλον επικρατούν οι αντιξοότερες συνθήκες. Βέβαια οι συνθήκες αυτές στη διάρκεια της χειμερινής περιόδου θα επικρατήσουν ελάχιστες φορές ή και καθόλου. Αυτό σημαίνει ότι, αν η θερμοκρασία δεν ελέγχεται από ένα θερμοστάτη χώρου, όπως π.χ. σε μια πολυκατοικία χωρίς αυτονομία, οι χώροι θα υπερθερμαίνονται, με αποτέλεσμα τη σημαντική απώλεια θερμικής ενέργειας. Δεν είναι λίγες οι φορές που σε πολυκατοικίες χωρίς αυτονομία, όπου η εγκατάσταση λειτουργεί με χρονοδιακόπτη, οι κάτοικοι των διαμερισμάτων να ανοίγουν τα παράθυρα για να μειώσουν τη θερμοκρασία του χώρου τους, ενώ ελάχιστοι είναι αυτοί που κλείνουν τους διακόπτες των σωμάτων, όπως είναι το σωστό.

Mixing Valve Controller
Thermoregulator EU-431N is intended for controling three- or four-way mixing valve with a possibility of connecting additional valvepump. Optionally, the controller may cooperate with two modules ST-61, which enables to control up to three mixing valves. The controlleris equipped with weather control function,weekly program and may cooperate with the room regulator. An additional advantage of the device is the protection of return temperature, which fulfils the function of protection against boiling ofthe water in the short boiler circulation or against too low temperature of the water returning to the water boiler.

GSM module
Control your boiler and CH installation via mobile phone
Principle of operation
GSM module is compatible with TECH controllers with RS communication and enables remote control of the boiler with the use of a mobile phone. The user is informed with an SMS about each alert of the boiler controller. Additionally, by sending an appropriate SMS at any time, the user receives information about the current temperature of all active sensors. After entering an authentication code it is also possible to remotely change the set temperatures. EU-65 module has 4 additional sensor inputs (2 temperature inputs and 2 contact inputs) operating independently from the boiler controller, to be used in any configuration. When the temperature sensor reaches its maximum or minimum set value, the module automatically sends an informing SMS . The same procedure applies in the case of opening or closing of the contact input.
