Energy savings
Energy savings rules advice to use mixing valves on water deliverysystems for sanitary use with storage, to limit the temperature of thewater at the inlet of the delivery network. The purpose of limiting thetemperature is to reduce passive dispersion through the deliverynetwork as much as possible, besides prevent delivering water ata higher temperature than necessary.
Reference documents
With regard to the prevention and control of Legionella, see theNational Regulations and applicable Code of Practice.
Applications
The electronic mixing valve is typically used in central systemsserving hospitals, nursing homes, sports centres, shopping malls,hotels, campsites and boarding schools. In these structures withtheir collective use, it is more than ever necessary to control andprevent legionnaire’s disease in a programmed manner, managingthe disinfection times in the best possible way.
Legionella-distribution temperature
In central systems that produce hot water for sanitary purposes withstorage, in order to prevent the growth of dangerous Legionellabacteria, the hot water must be stored at a temperature of at least60°C. At this temperature it is certain that the growth of the bacteriathat can lead to the illness called legionnaire’s disease will be totallyinhibited.These temperatures, however, are too high to be able to be useddirectly by the consumer; hot water at these levels can causesevere burns. It is therefore necessary to reduce the temperature ofthe hot water distributed in the network to a lower value compatiblewith use. In addition, not only the storage but also the entire distributionnetwork needs thermal disinfection at regular intervals. Otherwisethe bacteria would quickly form there too.
In the light of all this, it is therefore advisable to install an electronicmixing valve that is able to:
· reduce the temperature of the distributed water to an adjustablevalue lower than that of storage
· keep the mixed water temperature constant as the temperatureand pressure at the inlet or the draw-off flow rate of the mixedwater vary
· allow programming thermal disinfection with a higher temperaturethan the adjustment value, in the necessary time and in periods withless frequent consumption (nighttime).

Operating principle
At the mixing valve inlet there is hot water from the storage and cold water from themains. At its outlet there is the flow mixed water.By means of a specific sensor, the regulator measures the temperature of the mixedwater at the valve outlet and operates the mixing valve to maintain the set temperature.
It modifies the flows of hot and cold water at the inlet to bring the temperature of theoutlet water to the set value.Even if there are drops in pressure due to hot or cold water usage or temperaturevariations at the inlet, the mixing valve automatically adjusts the flow rate of water untilit obtains the set temperature.
The appliance incorporates a digital clock and allows programming anti-legionelladisinfection treatment on the plumbing system.The system is disinfected by raising the water temperature to a specific value for aspecific time duration.
For the best thermal disinfection control, in this type of system it may also benecessary to measure the temperature of the water returning from the network,measured with the recirculation sensor. When this measurement is available, it isused in order to check and control the temperature reached over all or part of thenetwork, since the sensor can be located at a significant remote point of the system.
The appliance is equipped with an RS-485 serial port for remote querying andsetting and via specific relays it carries alarm signals and controls for othersystem devices outside.

Work status
Depending on the time, according to the programs entered, the appliance may be in one of the following work modes:
• Adjustment;
• Disinfection;
• Flushing;
• Thermal shock (this function takes priority over the preceding ones);
In the event of trouble due to the appliance or the system, the device manages and reports the alarm and, depending on the situation, may maintainoperation or not. So the statuses include:• On with alarm• Off with alarm
The appliance is equipped with a chargeable battery that enables keeping the clock working in the event of a mains power failure.In the event of a blackout, in order to ensure the longest operating time possible for the battery, the appliance is in the status of:• Off with Low Power.
Adjustment In this mode the appliance continually checks the temperature detected by the flow sensor and as a result adjusts the mixing valve so that the flowtemperature is equal to the set point.
Disinfection In this mode the appliance runs a disinfection phase, which consists of taking the water temperature up to a pre-set value for a specific duration, suitablycontrolling the mixing valve.It is possible, with the menu, to set the days of the week when disinfection must be carried out.
At the end of disinfection, the statistical data relating to the disinfection that has just been concluded are stored in memory.Access to and exit from this mode take place automatically according to a time for starting (TIMEON) and ending (TIMEOFF) that the user can set.
If, in the time span (Time OFF - Time ON), the actual disinfection time is reached tDIS greater than the set tMIN, the disinfection is concluded with apositive outcome. It automatically exits this status and returns to adjustment.
If it is not possible to reach a sufficient time tDIS, the disinfection phase anyhow ends at Time OFF.

If, in the time span of 1 hour, there is a temperature higher than 60°C for at least 30 minutes, disinfection has beensuccessful and the regulator returns to adjustment. Otherwise, disinfection anyhow ends at 3:00.
Programs
The operation of the regulator, during disinfection, can be set according to different programs, chosen according to the type of system and itsmanagement:
Program 0 (default)This program features continual adjustment of the flow temperature with automatic disinfection in a time band that can be set. With this programthe return sensor is not used; if present, it is only used as a monitor.During the phase of disinfection, the temperature of the flow sensor must be above SET2 for a time tDIS at least equal to tMIN, if this occursthen disinfection has been successful.As soon as there are the conditions to be able to consider disinfection successful, it is stopped. If disinfection is not successful there is no alarmsignal.
Program 1AThis program features continual adjustment of the flow temperature with automatic disinfection in a time band that can be set. With this programthe return sensor is not used; if present, it is only used as a monitor.During the phase of disinfection, the temperature of the flow sensor must be above SET2 for a time tDIS at least equal to tMIN, if this occursthen disinfection has been successful.As soon as there are the conditions to be able to consider disinfection successful, it is stopped.If it is not possible to reach the disinfection temperature or it is not possible to hold it for a sufficient time, the alarm for unsuccessful disinfectionis generated. The alarm is recorded in the log.
Program 1BThis program can only be set if the return sensor is set as present.It is identical to the previous program, the only difference lies in the fact that the successful outcome of the disinfection phase is checked viathe return sensor in relation to SET3 instead of via the flow sensor in relation to SET2.As soon as there are the conditions to be able to consider disinfection successful, it is stopped.If it is not possible to reach the disinfection temperature or it is not possible to hold it for a sufficient time, the alarm for unsuccessful disinfectionis generated. The alarm is recorded in the log.
Program 2This program can only be set if the return sensor is set as present.It is identical to the previous program, the only difference lies in the fact that, if after a wait time (tWAIT) since the start of disinfection the returntemperature does not reach SET3, the flow temperature SET2 is increased by a value equal to (SET3 - TR reached), considering the fact thatSET2 anyhow cannot exceed the limit of SETMAX.This correction procedure (increasing only) of the disinfection SET is iterative: if necessary, it is repeated in the time span defined by TimeONand TimeOFF at each time interval equal to tWAIT.As soon as there are the conditions to be able to consider disinfection successful, it is stopped.If it is not possible to reach the disinfection temperature or it is not possible to hold it for a sufficient time, the alarm for unsuccessful disinfectionis generated. The alarm is recorded in the log.
Thermal disinfection
The temperatures and corresponding disinfection times for the network must be chosen according to the type of system and the relatedintended use. In the light of the requirements of the most advanced world legislation on this matter, the following criteria can generally befollowed:
T = 70°C for 10 minutes
T = 65°C for 15 minutes
T = 60°C for 30 minutes
Thermal disinfection is generally performed at times of reduced use of the system, for example at nighttime; this is to minimize the risk of usersgetting scalded. It is recommended to perform thermal disinfection every day and at least once a week.

Reset
On the back of the panel there is the reset button, if it is necessary to restore the initial settings.If the date and time are not set after the reset, the regulator will only make the adjustment according to the default settings.
Actuation relays
On the power and terminals board there are the contacts of the relays used to govern the auxiliary equipment and to report alarms.
• Relay 1: circulation pump (on in disinfection).
• Relay 2: general alarm (sensor fault, battery fault, blackout or loss of current time). This relay is connected via the NC contact.
• Relay 3: second thermostat.
• Relay 4: flushing valves.
Rese
t
FlushingThe appliance goes into this mode automatically at the end of the disinfection phase and it can be used for example to make the watertemperature return to the adjustment value more quickly or to periodically clear the storage of any impurities.
Thermal shock In this mode, the appliance regulates the flow temperature on the shock setting for a time that can be set. It is possible to start thermal shock on pressing the specific button on the front of the appliance (pressing it for at lease 5”) while the work screenis displayed, or to program it with the menu item for deferred execution (countdown in minutes), or by remote control.After activating the procedure, it is anyhow possible to stop it by pressing the shock button and confirming it with the “OK” button(display guided procedure), or by remote control.
At the end of the Thermal Shock phase the appliance goes back into the “adjustment” function.
Low PowerThis mode is entered if there is a mains power failure.The appliance continues running the internal date clock, however in this state there is no power to switch over the relays so the regulator willperform neither adjustment nor disinfection.When the mains power comes back on, the blackout is recorded in the log and the regulator returns to operating as programmed, unless themains failure lasted long enough to run down the battery completely. In this case the appliance will reset when the mains power comes back on.In the event of a reset or an extended power failure, the default settings are restored.

Log
The “log” is a FIFO list (loop buffer) that is continually updated and records parameters relating to the phases of adjustment and disinfectionthat took place during the day.The last 40 days are saved, after which the data relating to the less recent day are overwritten and so on.Every hour the hourly averages of the flow and return temperatures are saved to Eeprom, while the alarms are saved at the time when theyoccur.At any time it is possible to view the average hourly values of the current day (obviously the ones already recorded).The data on disinfection are saved when disinfection ends.It is possible to view the log on the display (via the specific menu item) or remotely via the RS485 serial interface.
The parameters saved in the log are:- Date (day, month, year)- Set program. This is saved when disinfection starts.- tDIS: actual disinfection time (in steps of minutes).When the set program is 0 or 1A, this parameter is the time when the temperature of the flow sensor was greater than SET2.When the set program is 1B or 2, this parameter is the time when the return sensor was greater than SET3.This is helpful when it is less than tMIN, to understand how much greater the span of TIME ON: TIME OFF should be to complete disinfection.- TRMAX: Maximum temperature of the return sensor during disinfection (if there was disinfection that ended on that day).- TRMIN: Minimum temperature of the return sensor during disinfection (if there was disinfection that ended on that day). It is calculated from the time when the return sensor measured a value greater than SET3, that is starting from the time when the disinfection starts being effective.
- Alarms AL1, AL2, AL3, AL4, AL5, AL6, AL7 if they were activated on the day in question.- 24 hourly average values of the flow temperature.- 24 hourly average values of the return temperature.- Marker indicating whether the previous data are reliable. Used in the event of resetting, changing time, changing date and any other event that might have made the saved data unreliable.
If no disinfection ended on that day, then the related fields will contain a default value.If there have been any faults with one or both sensors, the hourly average data will be displayed with dashes.If there are any “gaps” or unavailable data due to a change in date, time, etc., the cells will contain a default value and will be shown on thedisplay with dashes.
Ready for remote control
The regulator can be controlled by computer, too, since it is fitted with an RS485 serial output connection, which is accessible both via terminalsfor fixed wiring and via the connector on the front. Since the interface is the multipoint bus type it is necessary for each appliance connected on the bus to be identified by an appropriate addressin order to avoid conflicting identification.For a detailed description of the operations and controls that are possible from a remote location with this interface, please refer to the relevantdocumentation.

The software supplied with the interface is usedto manage the regulator, both during dataacquisition and during modification of theoperating parameters.In this way, it is possible to obtain information onthe status of the appliance even at a distance,pick up temperature values and alarmsrecorded in the backup files, pilot thermalshocks, change the settings of variousparameters. This type of control is particularlyuseful in the case of multiple installations withone or more appliances, which are all controlledby a single manager or maintenance technician.Typical examples of this are hotels, publicbuildings, schools, etc.

Anti-scald device for domestic hot water use, code 600140
Function
The purpose of the device is to cut off the flow of water if its temperature reaches the set value.Designed for use in domestic hot water systems with electronic mixing valves with programmable thermal disinfection.Installed directly at the point of use outlet, it prevents the hot water from scalding the user during the thermal disinfectionperiod (T>50°C).
Safety in use
As shown in the diagram opposite, temperatures ofmore than 50°C can cause burning very quickly.For example, at 55°C partial burning will occur in
approximately 30 seconds, while at 60°C partial burning will occurin approximately 5 seconds. These times are, on average, halvedfor children and elderly people.
Depending on the type of system and its intended use, togetherwith the relevant risk assessment, various devices can beinstalled to safeguard users from scalding caused by hot tap water.
