Operating principle
The electronic hybrid mixing valve combines the typical function
of the mechanical thermostatic mixing valve and the management
efciency of an electronic mixing valve in a single device.
The thermostatic mixing valve uses the mechanical action
performed by the internal control thermostatic element, which
responds promptly to any variation in temperature, pressure and
inlet ow rate to quickly restore the mixed water temperature value
at the outlet.
This standard mixing valve is effectively handled by a motorised
actuator that, upon the signal coming from the temperature probes
and under the control of a specic regulator, changes the mixed
water temperature set position.
The electronic regulator, directly on the actuator, allows the
mixed water temperature control according to different functional
programs, both for normal control and for the thermal disinfection
for the prevention of Legionella.
An optional memory system allows recording every minute of ow
temperature, return temperature, alarm and functional statuses,
useful for monitoring the operating status of the entire system.
Appropriate relays are used to manage the alarms and external
appliances, for example for loading accumulation hot water and
switching on/off the recirculation pump.
The regulator is tted for remote control with specic transmission
protocols such as MODBUS, through optional board, for use in
Building Management Systems (BMS).
The device is provided with CE mark in accordance with
directives 2014/35/EU and 2014/30/EU.
