<p>The control valve (1) includes a housing (12) in which two thermostatic valves (2,3) provided with respective thermostats (6,16) are arranged. Each of the thermostatic valves regulates the flow of hot water, independently. The thermostatic valve (2) controls the normal operation of control valve. The thermostatic valve (3) controls the disinfection process of the control valve, and limits the flow rate of hot water to zero, so that the hot water temperature does not exceed the predetermined threshold value. An independent claim is included for method of controlling water temperature for hot water circulation system during normal operation and disinfection process.</p> |
