Operating principle
At the mixing valve inlet there are the hot water from the boiler and the cold water from the water main. At the outlet there is the flow mixed
water.
Using a special probe, the regulator measures the temperature of the mixed water at the valve outlet and actuates the mixing valve to maintain
the set temperature.
The appliance has an integrated digital clock, which can be used to set anti-legionella programs to disinfect the water system.
The system is disinfected by raising the water temperature to a specified value for a specified length of time.
For better control of the thermal disinfection, it can also be necessary with this type of system to measure the temperature of water
returning from the network, measured with the recirculation probe. When this measurement is available, it is used to check and control the
temperature reached by all or part of the network, since the probe may be located at a significant remote point of the system.
The appliance is equipped with an RS485 serial port to allow remote setting and queries and through special relays, makes alarm
signals and controls available to other system devices.
