Room Thermostats

Room thermostats are control devices that are used to adjust the temperature in a space.

Each thermostat is designed to be connected to specific types of heating / cooling systems. Therefore, our future thermostat should state in its technical specifications that it is compatible with the system installed in the room.

They are distinguished in analogue (mechanical) and digital (electronic). ANDRIANOS has a complete range of thermostats of SALUS Company, covering the needs of modern heating and air conditioning.

Internet room thermostats (Wifi thermostats)

The rapid development of technology and the need for extra savings has led companies to create modern thermostats systems with increased communication and control capabilities.salus it 500 thermostatis wifi

Wifi Thermostat Salus IT500

The internet thermostats (wifi thermostats) give the option of remote parameterization via the internet in comparison with conventional thermostats. This has the ability to control and adjust the heating and air conditioning system from the PC, Tablet, and Smartphone.


Wireless thermostats and Chronothermostats

Room Thermostats, depending on how they are connected to the heat generating system (eg Boiler or Heat Pump), are distinguished in wireless and wired.

The wireless thermostats are communicating with the boiler via a wireless receiver that is installed in the boiler room and communicates wirelessly with the room thermostat installed in the building.

Room Thermostat Scheduling

An interesting function of the thermostats is the possibility of scheduling. Thermostats that have a time schedule can set a different room temperature according to a time schedule entered by the user.

With a chronothermostat, timing is possible in such a way that on the day, for example, the room has a temperature of 21 ° C and at night or the hours we are absent, 18 ° C. Changing the desired temperature is automatically done according to the program set by the user.

Advantages of scheduling:

- The room always has the desired temperature (eg in the morning we wake up) and is always maintained according to our needs.
- The heating system works more economically.

Thermostats PID ή PWM

Η λειτουργία PID ή αλλιώς PWM που έχουν οι πλέον σύγχρονοι θερμοστάτες αφορά τη δυνατότητα του θερμοστάτη να αντιλαμβάνεται κάθε στιγμή όχι μόνο ποια είναι η θερμοκρασία του χώρου ( όπως ένας συμβατικός ΟΝ/OFF θερμοστάτης), αλλά και πόσο γρήγορα αυτή μεταβάλλεται (ανεβαίνει ή κατεβαίνει), διατηρώντας έτσι τη θερμοκρασία του χώρου, σταθερή.

The PID or PWM function of the most modern thermostats refers to the thermostat's ability to perceive at any moment not only the temperature of the room (such as a conventional ON / OFF thermostat) but also how quickly it changes (rises or goes down) , thus maintaining the room temperature stable.

Operation: PID thermostats are equipped with a microprocessor which:

i. It compares the desired temperature and the current one at regular intervals
ii. It records how quickly the deviation between the desired and the current temperature changes
iii. It foresees future deviations

Result: Through the above analysis, the thermostat selects the operation of the heating system in such a way that it reaches and maintains the desired temperature with the fewest possible fluctuations.

PiD control thermostats can achieve excellent comfort conditions since the temperature is constant but also economical because the space does not heat up more than you need.

Οι θερμοστάτες PiD control μπορούν και επιτυγχάνουν εξαιρετικές συνθήκες άνεσης αφού η θερμοκρασία είναι σταθερή, αλλά και μέγιστη οικονομία, γιατί ο χώρος δεν ζεσταίνεται περισσότερο από όσο πρέπει.

Η τοποθέτηση θερμοστάτη PiD control ενδείκνυται σε εγκαταστάσεις ενδοδαπέδιας θέρμανσης (όπου η αδράνεια του συστήματος θέρμανσης είναι μεγάλη) και βελτιώνει δραστικά τη χρονική υστέρηση της θερμοκρασίας σε σχέση με την τιμή που ορίζουμε στο θερμοστάτη.

Χωρίς το παραπάνω να σημαίνει οτι οι θερμοστάτες PiD ή PWM δεν είναι η βέλτιση επιλογή για όλες τις εγκαταστάσεις θέρμανσης, αφού χάρη στην "έξυπνη λειτουργία" τους προσφέρουν αυξημένη θερμική άνεση και εξοικονόμηση ενέργειας.

PiD control thermostats can and achieve excellent comfort conditions since the temperature is constant but also economical because the space does not heat up more than you need.

PiD control thermostat installation is indicated in underfloor heating installations (where the inertia of the heating system is high) and drastically improves the time delay of the temperature relative to the value set in the thermostat.

However this does not mean that the PiD or PWM thermostats are not the optimal choice for all heating installations, because thanks to "smart operation" they offer increased thermal comfort and energy saving.

Central & Remote Control Systems

- Smart Home -

Modern centralized & remote control systems enable complete control of the heating and air conditioning system, even remotely, via the relevant web page or application on the smartphone and tablet. Those systems are usualy mentioned as Smart Home Systems.

The innovation of these systems lies in the fact that, in addition to heating and air conditioning, they can also control any electrical appliance or electrical system.
There is complete control of lights, electric shutters, garage doors, stand-alone air conditioners, electrical appliances.

In addition, Smart Home system include consumption meters to measure energy consumption, which, with proper analysis and corrective movements, offer extra savings.

Finally, it is noted that the individual Smart House systems, as well as the overall operation of the systems, are constantly evolving to control more and more points and functions in a modern home.


Salus IT 600 Smart Home System

SALUS iT600 Smart Home System gives you full control from anywhere via your Smartphone, tablet or PC. Up to 100 devices can be connected, such as: thermostats, smart plugs, window / door sensors on a gate, energy meters, etc.

salus it 600 susthma smart house

The system can be used to control the heating and air conditioning system with underfloor heating, radiator and fan coil. While using smart plugs, control of electrical appliances is achieved as well.

All units are wirelessly interconnected and there is the possibility of setting different rules to achieve optimal thermal comfort and energy savings.


Watts Vision Smart Home System

The Watts Vision system has a central control unit which communicates with the thermostats and the thermostatic radiator valves of each room. In addition, it has smartplugs for controlling electrical appliances and measuring electrical consumption.

The system is available with free apps (iOS, Android) for full control over cell phones and Tablet.

Thermostatic valves

Thermostatic valves are devices that are mounted on the radiator heaters and allow automatic adjustment of the hot water flow and consequently the temperature control of each space separately. They are the simplest way of autonomizing the heating of the spaces that have radiators.

Thermostatic valve in radiator

Function: They are placed locally on each separate heater and progressively adjust the flow of hot water on the basis of the room temperature. Thus, each radiator becomes independent and automatically isolates when the desired temperature is reached, while the other areas in need of heating continue to operate.

Result: When the building comes to thermal equilibrium, a smaller part of the overall system will work to achieve a fuel savings of up to 30%.
Thermostatic valves are distinguished in manual or automatic digital.

Thermostatic valves are divided into manual or automatic digital (electronic).

Compensation systems

Η Αντιστάθμιση είναι η διαδικασία ρύθμισης της θερμοκρασίας του θερμαντικού νερού προς τα θερμαντικά σώματα σε σχέση με τη θερμοκρασία του εξωτερικού περιβάλλοντος.
Το σύστημα αντιστάθμισης μπορεί να εγκατασταθεί στις περισσότερες υπάρχουσες εγκαταστάσεις θέρμανσης, ενώ θεωρείται απαραίτητη προσθήκη σε κάθε νέα εγκατάσταση.

Compensation is the process of adjusting the temperature of the heating water to the radiators in relation to the ambient temperature.
The compensation system can be installed in most existing heating installations and it is considered necessary to add to each new installation.

Function: Compensation is achieved by installing an electronic device, which, by taking ambient temperature measurements, adjusts the supply water temperature so that the indoor temperature is the desired temperature (at 20 ° C). Therefore, the body water temperature is not always large but stable.

Result: By installing a compensation system savings of up to 30% on heating costs are achieved.
