9 Catalogue information on serial numbers and PAW production system (PPS) PAW serial numbers PAW uses the serial number on almost all products since The serial number allows us to trace your HeatBloC or SolarBloC - back to the production. The serial number of the entire assembly is placed on the return pipe, the safety group or the Airstop so that it is clearly visible. Single components such as pumps, controller or actuators also have their own serial number. PAW documentation All PAW products are delivered with detailed installation and operation instructions in English, German, French, Spanish and Italian. Furthermore, we also offer commissioning protocols, data sheets, presentations, training and marketing documents for many products. From now on, you can find the instruction manual corresponding to your product with the serial number. Just scan the code of the serial number which is inside the installation. Under the tab Service/Documentation/PAW serial numbers, you will find an orientation aid where to find the serial number in the installation. Individual consultation The serial number guarantees optimum consultation in case of problems. Thanks to the serial number, our service team can access all the relevant data such as the list of items and the delivery date. They can check immediately whether the product is still under warranty and send you the required original spare part. By the way, we issue a 5-year warranty on PAW fittings. For further information, see page 282. If you need an individual consultation, do not hesitate to contact our service team via (serviceteam@paw.eu). PAW production system (PPS) At PAW, we constantly optimise our production and administration processes. "There is nothing that can not be improved!" is our slogan.

26 Conventional balancing of the distribution manifold Undersupply during parallel operation (optimised individual operation) Example 1 Initial state: Optimised individual operation Consequential problem: Undersupply during parallel operation Heating circuit 1 Heating circuit 2 Heating circuit 3 Heating circuit 1 Heating circuit 2 Heating circuit 3 Pump characteristic curve Pressure difference in m wc p Parallel operation Individual operation Control characteristic curve of the pump Initial state Flow rate in l/h Advantage: Energy-saving individual operation Disadvantages: Undersupply during parallel operation Raising of the heating characteristic curve or pump characteristic curve necessary Waste of energy Example 1: Undersupply during parallel operation All the control characteristic curves of the pumps are adjusted for individual operation. During the simultaneous operation (parallel operation) of several heating circuits, the pressure loss in the inlet increases, the system characteristic curve gets steeper. Along the control characteristic curve, the operating point shifts to the left and not upwards. Because of the revolution speed reduction, the generated pressure (Δp) is not sufficient. To counteract this undersupply, the heating characteristic curve and the control characteristic curve of the pump have been raised until now (see next page). Both measures lead to an increased energy consumption /2017 Printed in Germany PAW GmbH & Co. KG D Hameln Germany Phone: Fax: info@paw.eu

27 Conventional balancing of the distribution manifold Oversupply during individual operation (optimised parallel operation) Example 2 Initial state: Optimised parallel operation Consequential problem: Oversupply during individual operation Heating circuit 1 Heating circuit 2 Heating circuit 3 Heating circuit 1 Heating circuit 2 Heating circuit 3 Pump characteristic curve Pressure difference in m wc Control characteristic curve of the pump Parallel operation Individual operation p Initial state Flow rate in l/h Advantage: Security of supply during parallel operation Disadvantages: Excessively high return temperatures, increased fuel consumption during individual operation Additional costs Occasional whistling noises Example 2: Oversupply during individual operation In the design state, all heating circuits are adjusted to each other, the control characteristic curve of the pump is higher than in example 1. If heating circuits are switched off during parallel operation (f. ex. during holidays), the other heating circuits are oversupplied. Along the control characteristic curve, the operating point shifts to the right and not downwards. Because of the revolution speed increase, too much pressure (Δp) is generated. Whistling noises, excessively high return temperatures and an increased energy consumption are the results. 01/2017 Printed in Germany PAW GmbH & Co. KG D Hameln Germany Phone: Fax: info@paw.eu 27

The differential pressure controllers cause an increased pressure loss during individual operation (Δp on the right) and parallel operation (Δp on the left). To overcome this pressure loss, a higher control characteristic curve than in example 2 has to be set, resulting in an even higher energy consumption. The differential pressure controllers are expensive and inflexible /2017 Printed in Germany PAW GmbH & Co. KG D Hameln Germany Phone: Fax: info@paw.eu

32 Useful information on the hydraulic balancing Why choose the hydraulic balancing? For the hydraulic balancing of a big heating installation, not only the radiators must be balanced but also the heating lines at the distribution manifold (= balancing of the distribution manifold). The balancing of the distribution manifold is a necessary condition for a functioning hydraulic balancing of the entire installation. Only both aspects together ensure a comfortable heating of all rooms and an energy-efficient operation of the circulation pumps and the heat generators. Numerous funding programmes promote and require a hydraulic balancing when modernising a heating system. Static or dynamic? A distinction is made between the static and the dynamic balancing. The static balancing is carried out by restrictors with a fixed setting based on the dimensioning flow rate. This method generally implies the selection of a presetting at the thermostatic valve or at the regulating valve of the lines. This leads to less disadvantages at the radiator because, during the heating season, the heating output of the radiators is adapted to the varying outside temperature via the weather-compensated flow temperature. For the balancing of the distribution manifold, however, we recommend a dynamic balancing based on a regulation of the differential pressure. The PAW solution for the balancing of the distribution manifold! Our HeatBloC s from the MC series operate an electronic regulation of the differential pressure and build up exactly the pressure needed to cover the heat demand through the revolution speed control of the pumps. This ensures a sufficient valve authority of the thermostatic valves and improves their regulating mode. Flow rate variations due to mutual influence of the heating lines and a modification of the mixing valve position are avoided. The HeatBloC s MC save approximately 50 % of the pump energy compared to mechanical differential pressure controllers because all the energy produced is used efficiently. As the investment costs are nearly the same, the acquisition of a HeatBloC MC is profitable from the first day on! 32 01/2017 Printed in Germany PAW GmbH & Co.

49 Description of function K36 - DN 20 (¾") The K36 should always be used with a buffer tank, if not, a hydraulic separator is mandatory. DN 20 Thermal control valve with bypass Functioning: The thermal valve shuts off the connection to the consumers, as long as the water in the boiler circuit is colder than the opening temperature of the thermal control valve. The pump in the K36 circulates the water in the boiler circuit through the automatic bypass in the K36 which is completely open. When the water in the boiler circuit has obtained the opening temperature (+/- 3 K) of the thermal control valve, the valve opens the connection from/to the consumers. The bypass shuts off to the same extent as the connection to the consumers is opened. The control valve opens the return line from the consumers and enables thus the water to circulate in the consumer circuit. The cold water from the consumer return line is mixed in the control valve with the hot water from the bypass. Depending on the temperature and the flow rate of the water from the return line, the thermal control valve shuts off or opens the line to the consumers. Thus the return line which leads to the boiler always remains at a certain temperature level. With rising temperature in the flow line of the boiler or with rising temperature from the return line of the consumers, the thermal control valve opens the connection to the consumers. The temperature of the return line of the boiler remains nearly constant (+/- 3 K). Please note: When the boiler output is controlled by the boiler temperature, the boiler must heat up 20 K above the opening temperature of the K36. Otherwise, there will not be enough power available for the consumers (the boiler output may be reduced before the thermal control valve opens completely). 01/2017 Printed in Germany PAW GmbH & Co.

54 Hydraulic separators - DN 20 (¾") Description of function DN 20 Hydraulic separators are used when there are one or more heat generating circuits/primary circuits with pump and one or more consumer/secondary circuits with distribution pump in one system. Due to the working conditions in such systems, pumps affect each other and changes in throughput and delivery height can occur. The hydraulic separator causes a neutralization of the connected circuits. Thus, the primary and secondary circuit can work independently. The flow in one circuit does not cause a flow in the other circuit when the pressure drop in the hydraulic separator is insignificant. When a hydraulic separator is used, each circuit (the primary and the secondary one) must be equipped with a pump. Thus, a heat generating circuit/primary circuit can be provided with constant throughput and a consumer circuit/secondary circuit can be provided with variable flow. These are the typical functioning conditions for modern heating and air conditioning systems. The figures on the left side show three possible conditions of hydraulic stability. Hydraulic separators - DN 20 (¾") Item no. / piece up to 2200 l/h Completely made of brass, completely insulated with EPP insulation, for the installation below a modular distribution manifold DN 20 or separately on the wall (vertically or horizontally).

It must be considered that the pump of the boiler circuit must deliver a higher flow rate than the consumer pumps need in total. Otherwise, unwanted circulations occur on the right or left end of the low-loss header. In that case a hydraulic separator (item no or 31421) must be installed below a distribution manifold. Please note: When you plan the system you must already check whether a low-loss header can be used. In combination with central heating boilers, hydraulic separators must be installed below / upstream of a distribution manifold as the boiler delivers a flow rate with a high temperature difference (leads to unwanted circulation in low-loss headers).

81 Mounting equipment K33MAX - DN 25 (1") Thermal control valve, adjustable Function 1. The thermal control valve keeps the flow line of the mixing valve completely open as long as the water from the flow line to the consumer is colder than the limit temperature of the thermal control valve. 2. When the water in the flow line has obtained the limit temperature (± 5 K) of the thermal control valve, the valve shuts off the flow line of the storage tank/modular distribution manifold and opens to the same extent the return line (coming from the consumers). The cold water from the return line is mixed in the control valve with the hot water from the flow line. Depending on the temperature, the thermal control valve opens or shuts off the flow line of the storage tank/modular distribution manifold. 3. With rising temperature in the flow line or rising temperature from the consumer return line, the thermal control valve shuts off the inlet of hot water. The temperature of the flow line to the heat exchanger/ consumer remains approximately constant (± 3K).

85 Description of function Mounting equipment K35 - DN 25 (1") Mounting example with two HeatBloCs K35 with 3-temperature mixing valve and piping (rear view) 3-temperature mixing valve Mixing valve position 2.5 Mixing valve position 7.5 DN 25 The 3-temperature mixing valve is used in combination with a buffer tank, which can be heated by either a solar thermal installation, a solid fuel boiler or a conventional boiler. If the consumer only needs a low temperature level, such as radiant panel heating systems, the 3-temperature mixing valve first takes the the flow water from the intermediate part of the storage tank. When the temperature in this part is no longer sufficient, the hot water from the upper part of the tank is used. By using two parts of the storage tank for two different flow temperatures, the energy from the buffer tank can be used more efficiently. The return temperatures are low and the stratification in the tank is maintained.

87 Description of function K36E - DN 25 (1") The K36E should always be used with a buffer tank, if not, a hydraulic separator is mandatory. Thermal control valve with bypass Functioning: DN 25 The thermal valve shuts off the connection to the consumers, as long as the water in the boiler circuit is colder than the opening temperature of the thermal control valve. The pump in the K36E circulates the water in the boiler circuit by means of the automatic bypass which is completely open. When the water in the boiler circuit has obtained the opening temperature (+/- 3 K) of the thermal control valve, the valve opens the connection from/to the consumers. The bypass shuts off to the same extent as the connection to the consumers is opened. The control valve opens the return line from the consumers and thus enables the water to circulate in the consumer circuit. The cold water from the consumer return line is mixed in the control valve with the hot water from the bypass. Depending on the temperature and the flow rate of the water from the return line, the thermal control valve shuts off or opens the line to the consumers. Thus the return line which leads to the boiler always remains at a certain temperature level. With rising temperature in the flow line of the boiler or with rising temperature from the return line of the consumers, the thermal control valve opens the connection to the consumers. The temperature of the return line of the boiler remains nearly constant (+/- 3 K). Please note: When the boiler output is controlled by the boiler temperature, the boiler must heat up 20 K above the opening temperature of the K36E. Otherwise there will not be enough power available for the consumers (the boiler output may be reduced before the thermal control valve opens completely).

96 Hydraulic separators - DN 25 (1") Description of function Hydraulic separators are used when there are one or more heat generating circuits/primary circuits with pump and one or more consumer/secondary circuits with distribution pump in one system. Due to the working conditions in such systems, pumps affect each other and changes in throughput and delivery height can occur. The hydraulic separator causes a neutralization of the connected circuits. Thus, the primary and secondary circuit can work independently. The flow in one circuit does not cause a flow in the other circuit when the pressure drop in the hydraulic separator is insignificant. When a hydraulic separator is used, each circuit (the primary and the secondary one) must be equipped with a pump. Thus, a heat generating circuit/primary circuit can be provided with constant throughput and a consumer circuit/secondary circuit can be provided with variable flow. These are the typical functioning conditions for modern heating and air conditioning systems. The figures on the left side show three possible conditions of hydraulic stability.

Otherwise, unwanted circulations occur on the right or left end of the low-loss header. In that case a hydraulic separator (item no or ) must be installed below a distribution manifold. Please note: When you plan the system you must already check whether a low-loss header can be used.

123 Description of function K36E - DN 32 (1¼") The K36E should always be used with a buffer tank, if not, a hydraulic separator is mandatory. Thermal control valve with bypass Functioning: The thermal valve shuts off the connection to the consumers, as long as the water in the boiler circuit is colder than the opening temperature of the thermal control valve. The pump in the K36E circulates the water in the boiler circuit by means of the automatic bypass which is completely open. When the water in the boiler circuit has obtained the opening temperature (+/- 3 K) of the thermal control valve, the valve opens the connection from/to the consumers. The bypass shuts off to the same extent as the connection to the consumers is opened. The control valve opens the return line from the consumers and thus enables the water to circulate in the consumer circuit. The cold water from the consumer return line is mixed in the control valve with the hot water from the bypass. Depending on the temperature and the flow rate of the water from the return line, the thermal control valve shuts off or opens the line to the consumers. Thus the return line which leads to the boiler always remains at a certain temperature level. DN 32 With rising temperature in the flow line of the boiler or with rising temperature from the return line of the consumers, the thermal control valve opens the connection to the consumers. The temperature of the return line of the boiler remains nearly constant (+/- 3 K). Please note: When the boiler output is controlled by the boiler temperature, the boiler must heat up 20 K above the opening temperature of the K36E. Otherwise there will not be enough power available for the consumers (the boiler output may be reduced before the thermal control valve opens completely).

130 Hydraulic separators - DN 32 (1¼") Description of function Hydraulic separators are used when there are one or more heat generating circuits/primary circuits with pump and one or more consumer/secondary circuits with distribution pump in one system. Due to the working conditions in such systems, pumps affect each other and changes in throughput and delivery height can occur. The hydraulic separator causes a neutralization of the connected circuits. Thus, the primary and secondary circuit can work independently. The flow in one circuit does not cause a flow in the other circuit when the pressure drop in the hydraulic separator is insignificant. When a hydraulic separator is used, each circuit (the primary and the secondary one) must be equipped with a pump. Thus, a heat generating circuit/primary circuit can be provided with constant throughput and a consumer circuit/secondary circuit can be provided with variable flow. These are the typical functioning conditions for modern heating and air conditioning systems. The figures on the left side show three possible conditions of hydraulic stability.

It must be considered that the pump of the boiler circuit must deliver a higher flow rate than the consumer pumps need in total. Otherwise, unwanted circulations occur on the right or left end of the low-loss header. In that case a hydraulic separator (item no or ) must be installed below a distribution manifold. Union nut '' int. thread - See page 177 Please note: When you plan the system you must already check whether a low-loss header can be used. In combination with central heating boilers, hydraulic separators must be installed below / upstream of a distribution manifold as the boiler delivers a flow rate with a high temperature difference (leads to unwanted circulation in low-loss headers).

157 Return flow temperature maintenance Catalogue 01/2017 Valves and fittings for the use in hot water heating systems Valid for the UK

158 Return flow temperature maintenance with thermal control valve DN 20 (¾") / DN 25 (1") Application range Heating installations with return flow temperature maintenance For solid fuel boilers, wood-fired and stove heating systems The pump sets for the return flow temperature maintenance are groups of fittings for pumps that can be isolated. They consist of: High-efficiency pump Control valve with an opening temperature of 50 C, 55 C or 60 C 1 thermometer ball valve with a red dial thermometer integrated in the handle, can be pulled off 2 thermometer ball valves with a blue dial thermometer integrated in the handle, can be pulled off Connections DN 20: ¾" int. thread Connections DN 25: 1" int. thread Thermal control valve with automatic bypass 1. The thermal valve shuts off the connection to the buffer tank as long as the water in the boiler circuit is colder than the opening temperature of the thermal control valve. The pump circulates the water via the bypass, the small quantity of water in the boiler circuit can now heat up quickly. 2. When the boiler circuit reaches the opening temperature of the control valve, the valve reduces the bypass flow rate and opens the buffer tank circuit. The cold water from the buffer tank return is mixed with the hot boiler circuit water in the control valve. This leads to an increase of the return temperature in the boiler circuit to the desired level and avoids condensation in the boiler. 3. When the buffer tank return temperature is higher than the opening temperature, the control valve completely shuts off the bypass. Thus, the water from the buffer tank flows directly into the boiler circuit. Please note: If the boiler output is controlled by the boiler temperature, the boiler must heat up 20 K above the opening temperature of the return flow temperature maintenance. Otherwise, the boiler might reduce the output even before the thermal control valve is completely open. Mounting versions 1 and 2: Temperatures t BY = bypass t KR = boiler return t PR = return of the buffer tank t FIX = opening temperature Separate assembly of the group of fittings in the flow and return. This version permits an easy isolation of the heat generator without further shut-off valves. Consider the position of the safety group before mounting.

164 Return flow temperature maintenance with actuator DN 20 (¾") - DN 50 (2") DN 20 (¾") Application range Heating installations with return flow temperature maintenance for solid fuel boilers, wood-fired and stove heating systems Product description: The return flow temperature maintenance with actuator is a premounted group of fittings for heating circuits. The pump and the mixing valve can be isolated by means of the ball valves. An easy maintenance can thus be carried out without draining the heating circuit. DN 25 (1") DN 32 (1¼") Description of function: The pump set prevents the temperature in the boiler from falling under the dew point, thus reducing contamination of the boiler. The pump set is mounted between the buffer tank and the boiler. The actuator is controlled by an external controller. The actuator opens the 3-way valve only when the boiler circuit has reached the opening temperature set. By means of the mixing valve, the return flow temperature in the boiler is kept at a constant level and the maximum amount of energy for the storage tank charging is provided.
