Night mode, energy savings and other advantages of modern circular pumps on the example of the Alpha3 model.
It is known that the heating systems in modern cottages are so technically complex and extended that the heat carrier is properly circulated on them independently - under the action of their own gravity - absolutely no forces. For this purpose, special pumps are used that perform the "heart" function of the system: they work so that the coolant continuously circulated on the heating system with optimal hydraulic parameters. As in the human body, the efficiency and durability of the heating system depends on the proper work of the Heart. On the most interesting and useful functions of modern equipment of this type, we tell us on the example of new products from Grundfos - the Alpha3 automatic pump.
A standard three-speed circulation pump is continuously working with a predetermined speed (one of three), without not focusing on the actual parameters of the system. As a result, even if the pump was chosen correctly, due to the operation of the thermal head, it can create overpressure in the system. This is fraught with noise in pipes and uncomfortable working conditions.
Electronic adjustable pumps are able to adapt their performance for real working conditions. The mode of operation AUTOADAPT in ALPHA3 pumps is able to continuously analyze the hydraulic characteristics of the system and adjust the pump operation in such a way that it is most optimally corresponding to the actual working conditions. The result is a significant savings of power consumption, no noise in pipes and comfortable working conditions for the pump.
The novelty reacts optimally to abnormal situations. So, the function of reliable launch and an increased starting point ensure trouble-free launch of the pump, even if the equipment is not operated for several months in a row. Suppose the rotor is blocked by a blockage. Alpha3 is not confused in such a situation and try to free themselves on its own. For this, it will force his shaft to vibrate with a frequency of 3 Hz. This will help him get rid of the scale without third-party intervention. From a premature breakdown, the pump protects the built-in algorithm for protection against "dry" stroke.
As we have already mentioned, the functioning of the pump with a predetermined and maximum load-oriented speed is not the best characteristic. A good example is the night when there is no need to support daytime indicators. It is excellent that the Alpha3 model provides night mode. The pump enters it automatically after it determines that in the pressure pipe, the temperature of the coolant decreased by 10-15 ° C. Back, in normal mode, the equipment returns immediately, as the temperature of the coolant rises by about 10 ° C.
Another typical situation is "Summer Vacation" of heating systems. After this is the likelihood that lime deposits will appear in the latter. Potentially, these "zakisi" will interfere with the launch of the pump. In this case, the function of the summer regime will be unusually useful. After its activation, the pump once a day at the minimum speed for 2 minutes will drive a coolant over the system. It is worth noting that electricity in this mode is practically not spent.

Uponcing - to optimize the distribution of coolant flows (balancing the heating system). In the absence of such pumping equipment will be strongly exhausted, electricity is to be consumed above the norm, in addition, in rooms located near the boiler room, it will be too hot, in others there is not enough heat. At the same time, if the balancing is performed, then the cost of fuel and electricity will be saved to 20%. There is one "but" - the required works are difficult even for installers. Alpha3 pump with Alpha Reader communication module greatly simplifies the situation. In addition to him, the user will need downloaded to the smartphone or tablet GRUNDFOS GO BALANCE application and following step-by-step instructions. In this case, the balancing of the heating system in the cottage is approximately 200 m² to go a little more than an hour.
Another useful feature of the new equipment is compatible with Grundfos GO Remote. This is another application that is used to control and configure Alpha3. What is the benefit of Grundfos Go Remote? The application informs about the state of the pump, allows you to schedule its work and set the control mode. Grundfos Go Remote does not need additional devices: Pump connection - smartphone (tablet) runs through the Bluetooth Channel.

Efficiency: Alpha3, having balancing the heating system, will save on a fuel for a boiler to 8,000 rubles per year. *
* It is achieved due to the use of the hydraulic balancing function of the heating system in comparison with indicators of a hydraulically unbalanced heating system. The calculation is given in view of the indicators specified on the site, and depends on the conditions of heating (the size of the heated area, the duration of the heating season, the hydraulic characteristics of the heating system, the characteristics of the fuel).
