The total flow rate can be supplied with hot water dispenser is allowed to flow only total flow of the set flow rate value of the open valve,
The main flow control valve is controlled by the flow sensor and control operations.
The distribution flow for each valve, to adjust the opening of the electric valve in each room.
Accordingly, the hot water distributor, the pressure difference is always maintained constant, the maximum flow rate to be supplied to the dispenser is controlled not to exceed
the sum of the flow rate distribution that is assigned to all the valves. (Constant flow function)
