Page 30: Flush
4 Working with the master 4.3 Flush The flush of a line requires a valve that flows outwardly into a sufficiently large drain. The corresponding valves close completely. For safety reasons, only 1 flush valve is open during flush processes. The flush performance depends on the opening angle of the valve and the water pres- sure:... - Page 31 4 Working with the master The recorded components are first displayed.

Page 35: Trigger = Temperature
4 Working with the master 4.3.3.1 Trigger = Temperature The process is started for each individual valve depending on the temperature. Process sequence for cold water (Range = cold) The process is started if the water temperature exceeds the Temperature (default setting: 20 °C). - Page 36 4 Working with the master Process sequence for hot water (Range = hot) The process is started if the water temperature falls below the Temperature (default setting: 50 °C). The lines are now flushed with hot water. The Stop criterion (1) for the flush process is selectable: Either a defined Duration (default setting: 1 min), a Temperature to be exceeded (default setting: 55 °C), or a specific Volume for each flush valve.
-
Page 37: Trigger = Time
4 Working with the master 4.3.3.2 Trigger = Time The flush process is started time-dependent and then implemented for all flush valves in sequence, starting with the first flush valve. The process is started when the set Start time (default setting: 00:00 o'clock) is reached. The Stop criterion (1) for the flush process is selectable: Either a defined duration (default setting: 1 min), or a specific volume for each flush valve (2). - Page 38 4 Working with the master In the case of weekly execution, e.g. Mondays and Wednesdays every week, set the desired weekday, in the example here On weekday Monday and Wed- nesday: Under Every x weeks, set whether execution should take place weekly (x = 1, default settings) or less frequently (x >...

Page 39: Trigger = Usage
4 Working with the master 4.3.3.3 Trigger = Usage The prerequisite for this trigger is that each flush valve is connected to the respective flow sensor. The process is started for each individual valve depending on its usage. After each interval, the difference between the consumed water and the set target replacement Volume is flushed. -
Page 40: Protocols
4 Working with the master 4.3.4 Protocols Select frequency (1) of the protocols. Activate the selection with checkmark (4) or discard with x (3). The data recording takes place in line with selected recording rate (2). If the tem- perature difference between the recording points is ≤ 0.5 °C, no value is stored. During a flush process the temperature data is recorded every 2 seconds. -

Page 46: Type = Temperature
4 Working with the master 4.4.3.1 Type = Temperature The process is started upon reaching a specific temperature. Process sequence for hot water (Range = hot) If the hot water becomes colder than T hydr. balanc. (here: 57 °C, still thermally safe against legionella), then the process starts and opens the valve. - Page 47 4 Working with the master Risk of injury from hot water and components! Danger of burning and scalding during thermal disinfection! Make sure not to touch the components of the hot water circulation and the drain water during thermal disinfection. Please note that the components and the drained water require some time to cool down after the rinsing process.
- Page 48 4 Working with the master Process sequence for cold water (Range = cold) If the cold water becomes warmer than T hydr. balanc. (here: 25 °C), then the process starts and opens the valve. The resulting cold water circulation lowers the temperature.
-
Page 49: Type = Temperature Static
4 Working with the master 4.4.3.2 Type = Temperature static The process is started daily at a specific Start time. The start time must be selected in such a way that the process of static hydraulic balancing takes place at a time when no water is with- drawn, i.e. - Page 50 4 Working with the master Process sequence for hot water (Range = hot) At the set Start time the first valve regulates its flow to the set T hydr. balanc., in the shown example to 57 °C. Then the second valve regulates its flow, followed by the other valves, and finally the process is repeated until all valves reach T hydr.
-
Page 51: Type = Flow
4 Working with the master Process sequence for cold water (Range = cold) At the set Start time the first valve regulates its flow to the set T hydr. balanc., in the shown example to 15 °C. Then the second valve regulates its flow, followed by the other valves, and finally the pro- cess is repeated until the 4 hours have passed. - Page 52 4 Working with the master Process sequence First the respective valve must be selected under Flow rate. At the start of the Start time process, the opening angle (leakage rate) of each individual valve is set. During this, the valves sequentially adjust based on the flexible average flow of the past 24 hours and the set target valve Flow rate.
-
Page 53: Type = Fixed
4 Working with the master 4.4.3.4 Type = Fixed In this type, the opening angle set for the valve (leakage rate) is not changed. There are also no parameters to be adjusted. The system permanently maintains the opening angel set for each valve, for details of the setting see Leakage rate (>Settings >Valves). -

- Page 60 4 Working with the master Maintenance. The trigger is the automatic maintenance process. If a main- tenance process is started, the status switches to active and remains in place until the maintenance is completed. The status then switches back to not active. This can be used, for example, to trigger a disinfection measure or a flush pro- cess during the maintenance process.

Page 61: Automatic Maintenance Process
4 Working with the master 4.8 Automatic Maintenance Process Once a week, the Maintenance application is actuated. It ensures long-term reliable operation of the valves during hydraulic alignment. A basic prob- lem of hydraulic regulator valves is the fact that during operation they are never shut fully or only during maintenance measures. -
Page 62: Manual Operation
4 Working with the master 4.9 Manual operation The following functions are possible here: (1) Manual activation of individual valves (2) Joint activation (opening/closing) of LegioTherm valves according to type: all hydraulic balancing valves (LegioTherm 2T) all flush valves (LegioTherm K) (3) Manual operation of the connected actuators Risk of damage to the flow sensors! Flow sensors potentially installed to flush valves can be damaged if the flow speed is too high (opening degree = 100%)! -
Page 63: Valve

Page 64: Valves
4 Working with the master 4.9.2 Valves The dialog allows the service technician to manually open and close the selected valves (max. 5 valves at a time). During this, the valves open and close completely (opening degree 100 %/0 %). In flush valves this can lead to a high water output! Select the desired valve type (all, flush valves or hydraulic balancing valves). -

Questions and answers
某小区直饮水项目，自来水在小区进行中央净化处理后，通过管路输送至每栋楼住户。入户主管为DN32，回水是DN25。为防止军团菌滋生，直饮水均做成循环管路，每4小时循环一次，将管网中水回至设备房。现在需要可以准确计量，同时能实现各环路自动平衡的阀门，以方便后期调试、计量和维护。目前，通过推广工作，甲方对Hycleen产生兴趣，但对于是否能准确计量和平衡还有疑问： 问题1：Hycleen是否能用于直饮水系统内（冷水）各环路的平衡？如果能，选择哪种型号比较合适？ 问题2：在国外有没有有用于直饮水系统的案例。 问题3：Hycleen外挂在平衡阀上的涡轮流量阀用的哪一种信号，准确率有多高？ 问题4：Hycleen各阀门之间是如何进行自动平衡水路压力的？是否可靠？ 以上几个问题，设计师和甲方都迫切地希望了解，毕竟目前国内还没有这方面的应用案例，希望我们的回复能增强他们使用Hycleen的信心。
