Function
The electronic mixing valve is used in centralized
systems that produce and distribute domestic hot
water. It maintains the temperature of the domestic hot
water delivered to the user when there are variations in
the temperature and pressure of the hot and cold water
at the inlet or in the draw-off flow rate. The LEGIOMIX ®
electronic mixing valve provides precise temperature
control over very low and very high flow rate demand,
minimal pressure drop with a ball valve control element,
automatic self-cleaning to prevent scale formation and
easy-to-use digital interface with data logging, alarming
and status indication. The LEGIOMIX ® electronic mixing
valve is furnished with a controller with LCD user
interface that provides a set of programs for circuit
thermal disinfection to kill Legionella. The controller is
