Such heating control devices reduce the temperature of the heating water, not the room temperature. This means that the changes only affect the heat delivered to the rooms, while what actually happens in the rooms remains uncertain because the heating system is equipped with a heat curve, but each room has different heat losses and gains. In fact, each room requires its own curve because using one common curve results in the same situation as in a private house with an unregulated boiler – for one room it will mean +24 °C when the outside air temperature is low, and +20 °C – when the outside temperature is higher, and vice versa for another room. Therefore, mechanical or electronic thermostats (thermo heads) without centralized control are usually additionally installed. These radiator thermostats compensate for regulation of the heating system.

On the other hand, if the adjustment is not reduced in the evening for the mechanical thermostat (of course, if reduced, then the room will be cold in the morning), this thermostat compensates for the lower heating water temperature with a larger radiator opening. In other words, if during the day water with a temperature of 40 °C enters the radiator and the thermostat opens the flow in the radiator to 50%, then at night, when the incoming water temperature is 36 °C, the radiator will work at 80% to maintain the temperature set in the thermostat. As a result, the same amount of heat energy is consumed as in the case of higher set temperatures; the only difference is that in some rooms the radiator may be smaller (during the day it already worked at 100%) or the window left open, and in such lower temperature situations, an emergency situation is possible – even if the radiators are not frozen, indoor plants could freeze. Therefore, in large buildings with more than 50 heating radiators, reducing heat at night or on weekends without regulators that regulate each radiator individually but receive regulation Therefore, in large buildings with more than 50 heating radiators, reducing heat at night or on weekends without regulators that regulate each radiator individually but receive regulation settings synchronously to ensure that the building's heating operates as a single mechanism is inconceivable. Other manufacturers position such a set of smart thermostats as the most expensive version, but for us, it is the only correct version, because it is the only one that really works in large buildings. And large buildings are our main advantage – we are the first to create a smart thermostat system where more than 1000 devices can be included in one installation, so the number of radiators in the building is not limited.
