When installing a waterproof system, a water-mixing unit is installed to maintain a certain temperature and connection of the secondary and primary circulation contours of heating. For group regulation of several rooms or zones, various automation for warm floors is used. Through the communicator, using the circular pump of the mixing unit, you can adjust both the flow rate of the coolant, and set the temperature in the room. Also, the temperature can be controlled by an electronic indoor thermostat, which automatically switches the heating mode, when the value reaches the set mark. Surprising thermostats are used to prevent the possibility of entering a circulating liquid with a high temperature in the collector. Control of the heating mode of warm floors can be carried out by setting the program for a week or a day by an electronic chronotherapist Valtec.
