VL.GP.J1.02 Danfoss 10/2012 Bypass (thermostatic circulation) The water heater is supplied with a thermostatically controlled bypass, which ensures that hot water is produced immediately, when tapping starts. The bypass temperature is set with due consideration of the best possible comfort and economy. Domestic hot water circulation The water heater is prepared for domestic hot water circulation. If the household piping includes hot water recirculation the water heater must be connected to the hot water recirculation system and a circulation pump and a non-return valve must be mounted on the circulation pipe and a safety valve must be mounted in the DCW inlet. The pump must be installed so that it pumps towards the water heater. Domestic hot water circulation ensures that hot water is available at the tapping point without waiting time and waste of water. The circulation temperature is set independently of the set temperature. This ensures the best possible comfort, very low standby losses and thus a very good district heating economy. Please note that Akva Vita II with AVE expansion unit should not be used on systems with domestic hot water recirculation. Heat exchanger for heating The water heater is based on a brazed, highly efficient plate heat exchanger type XB 06H-1 26, which is controlled by a pressure controlled controller, Danfoss PM+P with integrated differential pressure controller and e save TM function, which ensures that the heat exchanger is cold during standby. After completion of the tapping process, the controller immediately blocks the district heating flow, to avoid standby losses and to protect the heat exchanger from the formation of lime scale and growth of bacteria. The heat exchanger is cold during standby, so the heat loss is very low. The integrated differential pressure controller compensates for variations in supply temperature and varying differential pressure and thereby ensures a constant hot water temperature at all times. Service and maintenance The water heater is very service-friendly and easy to install. It is mounted on the wall and as all pipes are placed in pipe bracket distance, it is possible to establish a nice piping. Features and benefits COLD heat exchanger during standby, - no standby losses controller PM2+P with integrated differential pressure controller and e save TM function Pipes and heat exchanger made of stainless steeel, connections with EPDM gaskets.

As a result, the following operation modes can be defined for the ThermoDual charging system: Low Load Operation During low load operation, all of the cold water flows through the heat exchanger (HEL). If the tap output is smaller than the flow pre-set by the balancing valve, a portion of the hot water (tap flow) flows to the tap locations in the upper part of the tank (DTA) as a bypass. The residual water is removed from the bottom of the tank (DTA), causing the tank (DTA) to be continually charged. The total tap output is covered by the heat exchanger (HEL), while the storage tank (DTA) is not being discharged. Peak Load Operation During peak load operation (higher demand that can be supplied by the available heating power), the pre-set cold water flow flows through the heat exchanger (HEL) and the residual water streams from the bottom to the top of the storage tank (DTA). The tap output is covered by the heat exchanger (HEL) while the domestic water storage tank (DTA) is being simultaneously discharged. Once tap operation ceases, the storage tank (DTA) is charged as described below. DEN-SMT/PL VD.KR.C4.02 Danfoss 12/2013 5

21 Data sheet ThermoDual charging system Charging Operation (no consumption) If there is no consumption the storage tank (DTA) is being charged. The total charging flow is removed through the bottom of the tank (DTA) and returned through the top of the storage tank (DTA) via heat exchanger (HEL). If the storage tank (DTA) is completely charged and no output consumption occurs, the control valve (CVS / CVE) closes and interrupts the heating water flow.

The bypass temperature is set with due consideration of the best possible comfort and economy. Domestic hot water recirculation The water heater is prepared for domestic hot water circulation. If the household piping includes hot water recirculation the water heater must be connected to the hot water recirculation system and a circulation pump and a non-return valve must be mounted on the circulation pipe and a safety valve must be mounted in the DCW inlet. The pump must be installed so that it pumps towards the water heater. Domestic hot water recirculation ensures that hot water is available at the tapping point without waiting time and waste of water. The circulation temperature is set independently of the set temperature. This ensures the best possible comfort, very low standby losses and thus a very good district heating economy. Heat exchanger for heating The water heater is based on a brazed, highly efficient plate heat exchanger type XB 06H-1 26 or XB 06H-1 40, which is controlled by a thermostatic and pressure controlled controller, Danfoss PTC2+P with integrated differential pressure controller and energy saving function, which ensures that the heat exchanger is cold during standby. After completion of the tapping process, the controller immediately blocks the district heating flow, to avoid standby losses and to protect the heat exchanger from the formation of lime scale and FeATURES AND BENEFITS Prepared for low-temperature district heating Fully insulated and very low heat losses Cold heat exchanger during standby, - no standby losses controller PTC2+P with integrated differential pressure controller and energy saving function Pipes and heat exchanger made of stainless steel, connections with EPDM gaskets. Minimized risk of lime scale and bacteria formation Capacity: up to 53 kw growth of bacteria. The heat exchanger is cold during standby, so the heat loss is very low.

34 Data sheet ThermoClean Domestic water heating system with legionella growth prevention through thermal disinfection Description/Application The ThermoClean system is compact and effective solution for legionella-free domestic water heating. The system uses the thermal disinfection methods, whereby the reaction temperature inside the installation is kept at a constant temperature of 70 C. The ThermoClean system is dimensioned in such a way that the water is warranted to remain in the reaction area of the device for at least 5 minutes. During tap operation, the reaction temperature of 70 C is cooled down to the required hot water temperature within the system. This is not achieved by the addition of cold water, but through an additional re-cooling heat exchanger which cools the disinfected water, while preheating cold water, that simultaneous preheat the cold water. The hot water temperature can be set at any temperature between 50 C and 60 C. 1 It means that the installation of a scaling protection device on the taps is redundant if the temperature is adjusted accordingly. Due to the connection of the circulation into the system a continual thermal disinfection of the hot water is ensured. The high quality stainless steel design of reaction and buffer storage tank, heat exchanger and piping is hygienically perfect, offers a maximum in operational safety and can be universally used in combination with the wide range of materials used in the connected domestic water supply network.

36 Data sheet ThermoClean Domestic water heating system Accessories 4 ThermoClean -DL 1. Domestic hot water storage tank The ThermoClean system must be combined with additional domestic hot water storage tanks to provide the required capacity for peak consumption. The required storage tank capacity is based on the calculated peak flow and the length of the consumption period. The recommendations provided overleaf for the total storage tank capacity are based on peak consumptions lasting 1 hour or according to customer demands. If the consumption periods are shorter, the storage tank capacity can be reduced accordingly. We recommend the utilization of the following storage tanks: - Stainless steel domestic hot water storage tank series SE, - Tank sizes: liters, - Optimum adaptation to requirements due to optional combination of multiple storage tanks. 2. Over-tapping protection Several unexpected factors can result in the complete consumption of the available storage tank capacity, which again can lead to the addition of domestic cold water to the hot water network that has not run through a proper thermal disinfection. The potential causes are for example: - Heating medium not available in sufficient quantity or at the adequate temperature, - Insufficient heat transfer in the heat exchanger due to fouling, - Technical defect of a system component (e.g., failure of the charging pump), - Peak consumption continues longer than the calculated consumption period. To address this issue, we offer products complementing our ThermoClean system that provide effective protection against system overtapping. If the storage tank capacity of thermally disinfected domestic water is beginning to run out, the protection interrupts the cold water supply to the system until the charging process has once again provided sufficient quantities of thermally disinfected domestic hot water via the reaction storage tank. Only after this process is complete, the cold water supply is established and the tapping of domestic hot water can be continued. The device is controlled via the ThermoClean system control with a manual switch (ON/OFF/AUTOMATIC). Over-tapping protection consisting of: - Motorized butterfly valve, nominal diameter corresponds to the selected ThermoClean system, actuator 1~230 V, three-point signal, - Control thermostat with stainless steel immersion pocket.

A temperature sensor at the exit of the heat exchanger monitors this temperature and regulates the application of heat energy accordingly. The system is dimensioned to ensure that the domestic hot water remains in the reaction area for at least 4 minutes to warrant the extermination of the legionella bacteria. The entire system volume is maintained at the defined disinfection temperature. Only when the water is tapped, the required quantity of water is cooled down to the demanded network temperature ( C) while the new cold water that is being added is preheated. Temperature fluctuations are balanced out by the mixing valve, so that the precise degree of water temperature indicated is definitely being maintained. Proven control technology ensures that the domestic hot water network is not heated up during breaks in tapping. If the consumption volume during peak times exceeds the charge flow of the system, the available storage tank volume is tapped. The optionally available over-tapping protection ensures that during unexpected functions (e.g. peak tapping continues for a period exceeding the determined consumption period) the cold water supply is suspended until sufficient thermally disinfected domestic water is once again available through the charging process via the reaction tank. The circulation water from the network enters the system, is once again heated up to 70 C by the charge heat exchanger and consequently incorporated into the thermal disinfection process continually. 4 VD.KR.D5.02 Danfoss 09/2014 DEN-SMT/PL

48 Data Sheet ThermoDual -FLS (welded type) Function Flow systems provide heated domestic water when requested. By a heat exchanger (HEL), the cold water flowing into connection (1will be heated up to set point and provided to the consumer at the connection (2). The electronic controller (ECD) is measuring the relevant temperatures and controls the target values that are held constant in all operating conditions. This is i.e. achieved by influencing the speed of the heating pump (HPU), so that the outlet temperature always matches the specified value. In case of using a control valve, the flow is directly controlled by an electrical actuator. Short-term peaks in consumption are registered at the flow sensor to intervene quickly and avoid large temperature fluctuations. The cooled- circulation water from the network (connection 3) is constantly heated in heat exchanger (HEL), even in times of draw-off, reheated and the temperature control (sensor) in the amount of the controlled circulation pump ( CPU) influenced so that only the necessary amount flows to maintain constant power set point. The capacity for the peak load is to ensure either by buffering heating water in a tank (BTA) or there must be a sufficiently large connection value available. The Recharging of a buffer (e.g. from a boiler) can a requisition (sensor / switch contact) on controller (ECD) using an on-site charging pump (LPU). The operation of the system by a controlled heating pump (HPU) is only possible without differential pressure between the connections (4) and (5).
