AUDAX TOP ErP and Integrated System

voltar.com.ua

4 INTEGRATED SYSTEM FOR AIR CONDITIONING AND D.H.W. PRODUCTION

Comprised of a boiler – solar heating – heat pump and possibly photovoltaic – etc, they are the natural evolution of air-conditioning systems: with very high seasonal eciency, low energy consumption and reduced polluting emissions. ey are engineering solutions that can be perfectly integrated with each other, which allow to attain maximum benet from the various energy production systems on the basis of the respective eciency parameters. For the entire system to operate correctly, Immergas oers a System Manager, able to:

- always make use of the most convenient heat source;

- keep the system performance high in every circumstance;

- control and command the entire system with a unique "brain" (i.e. the System Manager);

- promote heat pump activation with a system that generates electricity from renewable sources.

Basically, the System Manager is a supervisor that can control the entire system). Amongst other things, the following main operations are necessary:

voltar.com.ua

- acquire outdoor temperature (from the external probe, inserted

- set central heating side and cooling side (if provided) climatic

- congure the fuel cost (e.g. methane);

- congure the electric energy cost;

- set the AUDAX TOP ErP minimum integration (cut o) T. e point of economic balance between the gas boiler and the heat pump is a COP value between 2.4 and 2.6 approximately (approximate value referred to methane); this value changes based on the cost of electrical power and gas, in the location

voltar.com.ua

where the system is installed. With sucient Toutdoor to full minCOP economical convenience, or Toutdoor is higher than Tminimum integration (cut o), the heat pump starts and the performance eciency conditions are constantly monitored. On the contrary, if the environmental conditions are such that the AUDAX TOP ErP coecient of performance tends towards lower values than COPmin for economical convenience, or outdoor T is less than minimum integration

(cut o) T, the system Manager starts the boiler (or integrative

resistance).

voltar.com.ua

AUDAX TOP ErP and Integrated System

voltar.com.ua

Each time AUDAX TOP ErP is operating, the Manager enables an additional control, which checks the time it takes the system to reach full operation: when a maximum time is exceeded (can be set dierently between C.H. and D.H.W.) for the heat pump to reach the owT, the boiler or integrative electrical resistance is started. It is also possible to choose the integration operation method (boiler/resistance) between simultaneous or alternative Heat Pump. In all cases where radiant panels are also included for summer cooling, alongside dehumidiers (see previous picture), the System Manager will also monitor the dew point through the installation of room probes (Immergas). anks to this intelligent function the System Manager can increase the ow temperature to the radiant panels by about 1°C (up to a maxT of 18°C - maximum limit of the cooling heat pump), avoiding the phenomenon of condensation on the surface of the structure. is function can only be activated with an Immergas accessory kit that controls humidity. In some cases, for example, the System Manager can turn the heat pump o if the ow temperature to the radiant panels is not suciently corrected.

voltar.com.ua

If on the other hand, there is a high temperature zone in the system, in addition to the low temperature one, it will be served exclusively by the boiler through an accordingly congured dedicated expansion connected to the System Manager. D.H.W: operation: amongst the possible congurations with integrated systems is the option to connect the boiler and AUDAX TOP ErP parallel with the same coil, and use a storage tank probe with one DHW set for the entire storage tank, and set

voltar.com.ua

it in the system's Manager. If the system Manager is connected to the boiler on external probe clamps (pre-set models), if the set DHW temperature is < 50°C, the heat pump starts (always checking the aforesaid convenience); however, if it is > 50°C, AUDAX TOP ErP heats up to 50°C, then the boiler starts; if there is no boiler but there is storage tank integrative electrical resistance, the water is brought to 50°C via the heat pump and AUDAX TOP ErP is then disabled, leaving the resistance to integrate to the pre-set value. In systems where there is a boiler or an integrative electrical resistance on the storage tank, in addition to the heat pump, it is also possible to enable the anti-legionella function.

5 HEAT ADJUSTMENT WITH AUDAX TOP ErP CONTROL PANEL IN STANDALONE APPLICATIONS (SETTING AND LOGIC OPERATION)

e Control Panel (standard supply with AUDAX TOP ErP) enables programming of several operating options and relative

voltar.com.ua

temperature/humidity control of the system.

voltar.com.ua

For example, the Control Panel acquires data regarding outdoor temperature (from the external probe), system ow temperature (regarding the pre-set climatic curve), and also the room's humidity percentage. e standard Control Panel supplied is connected to a specic terminal block on AUDAX TOP ErP, which enables you to program the machine and also functions as a room temperature/ humidity sensor. It also displays the error codes in the event of malfunctions. e room sensor function can be disabled in order to use it only to display the heat pump statuses and leave AUDAX TOP ErP external control management on/o. e user interface is composed of an LCD display, keys and an encoder central knob.

voltar.com.ua

N.B.: With system Manager applications, the Control Panel (standard) can also function as a room temperature/humidity probe of a system's zone.

Place of installation:

e place of installation is very important and must be established by the system's designer or by a specically qualied person, and must consider the technical requirements, standards and laws in force.

• e unit must be installed outdoors only;

• It is recommended to avoid:

- positioning in basement windows

- obstacles or barriers that cause recirculation of exhaust air;

- places with aggressive atmospheres;

- limited spaces or anyhow in places where sound levels from the appliance can be enhanced through reverberations or resonance;

- positioning in corners where there is an accumulation of dust, leaves and anything else that can reduce the appliance's eciency due to blocked passageways;

- prevent exhaust air from the device from coming into the rooms through doors or windows, thus disturbing people;

voltar.com.ua

300

voltar.com.ua

500 500500200

• e appliances must:

- be placed on a level surface that is able to withstand its weight;

- be placed on a slab that is hard enough and which does not transfer any vibrations to the underlying or adjacent rooms;

- use the vibration-dampening supports supplied with the machine.

• If the unit is installed in zones subject to heavy snow, it will

voltar.com.ua

be necessary to raise the machine by at least 200 mm above the normal level reached by the snow, or alternatively use the wall-support bracket (optional).

• If deectors are present to protect the unit against strong winds, these deectors must be studied so as to avoid obstructing the normal air circulation.

NOTE: AUDAX TOP 18-21 ErP is equipped with antifreeze protection comprising an electrical resistance to protect the plate exchanger which is the most critical component with regard to freezing. When the electrical resistance activates so does the pump inside the AUDAX TOP 18-21 ErP, in this way, with power supply voltage, the machine is protected up to -10°C. If AUDAX TOP 18-21 ErP is installed in areas having temperatures below 0 °C, it is recommended to provide special antifreeze systems in order to guarantee the machine's integrity, especially the water-gas heat exchanger, when there is a blackout. For example, insert top quality, non-hazardous antifreeze liquid into the heating system.

In this case, the instructions of the manufacturer of this liquid must be followed scrupulously regarding the percentage necessary

voltar.com.ua

with respect to the minimum temperature at which the system must be kept. An aqueous solution must be made with potential pollution class of water 2 (EN 1717:2002). With no supply voltage and if no antifreeze liquid has been inserted, you must drain the water from the machine. Avoid using automatic lling systems.

13.1 AUDAX TOP 6 ErP PUMP SETTINGS AND CONFIGURATIONS

AUDAX TOP 6 ErP range boilers are supplied with a low power consumption pump with variable speed control. e circulating pump is equipped with electronic control to set advanced functions.

Constant head (∆P C) (Ref. 4 above g.) default setting. e circulator pump maintains the pressure level (head) constant as the system heat demand decreases (ow rate reduction). With these settings, the pump is suitable for all oor systems.

voltar.com.ua

KEY: 1 - Automatic vent mode operation 2 - Light ring to indicate the operating status 3 - Proportional head operation 4 - Constant head operation 5 - Operating mode selector switch

voltar.com.ua

Proportional head (∆P V) (Ref. 3 above g.). is allows the pressure level (head) to be proportionally reduced as the system heat demand decreases (ow rate reduction). anks to this function, the electric power consumption of the circulator pump is reduced further: the energy (power) used by the pump decreases according to the pressure level and ow rate. With this setting, the pump guarantees optimal performance in most heating systems, proving particularly suitable in single-pipe and two-pipe installations.

voltar.com.ua

TECHNICAL NOTE: System minimum water content:

To facilitate proper execution of the AUDAX TOP ErP heat pump defrost cycles, a minimum water content in the system is required, which must be: 6 l/kW of the machine's power for any type of system. e ywheel guarantees normal operation of AUDAX TOP ErP with systems divided into zones (with variable water content in circulation). e ywheel also guarantees proper operation with fan coils used for cooling (a condition in which the ow temperature is very low and has signicant heat load variations that vary the number of active fan coils). It is also important to check that the dehumidier line has a minimum of 3 l/kW of the machine (dehumidier hydraulic circuit connection). N.B.: for inertial tanks codes supplied by Immergas, refer to page 107.

17.1 AUDAX TOP 8 ErP PUMP SETTINGS AND CONFIGURATIONS

AUDAX TOP 8 ErP range boilers are supplied with a low power consumption pump with variable speed control. e circulating pump is equipped with electronic control to set advanced functions.

Constant head (∆P C) (Ref. 4 above g.) default setting. e circulator pump maintains the pressure level (head) constant as the system heat demand decreases (ow rate reduction). With these settings, the pump is suitable for all oor systems.

voltar.com.ua

KEY: 1 - Automatic vent mode operation 2 - Light ring to indicate the operating status 3 - Proportional head operation 4 - Constant head operation 5 - Operating mode selector switch

voltar.com.ua

Proportional head (∆P V) (Ref. 3 above g.). is allows the pressure level (head) to be proportionally reduced as the system heat demand decreases (ow rate reduction). anks to this function, the electric power consumption of the circulator pump is reduced further: the energy (power) used by the pump decreases according to the pressure level and ow rate. With this setting, the pump guarantees optimal performance in most heating systems, proving particularly suitable in single-pipe and two-pipe installations.

voltar.com.ua

TECHNICAL NOTE: System minimum water content:

To facilitate proper execution of the AUDAX TOP ErP heat pump defrost cycles, a minimum water content in the system is required, which must be: 6 l/kW of the machine's power for any type of system. e ywheel guarantees normal operation of AUDAX TOP ErP with systems divided into zones (with variable water content in circulation). e ywheel also guarantees proper operation with fan coils used for cooling (a condition in which the ow temperature is very low and has signicant heat load variations that vary the number of active fan coils). It is also important to check that the dehumidier line has a minimum of 3 l/kW of the machine (dehumidier hydraulic circuit connection). N.B.: for inertial tanks codes supplied by Immergas, refer to page 107.

21.1 AUDAX TOP 12 ErP PUMP SETTINGS AND CONFIGURATIONS

AUDAX TOP 12 ErP range boilers are supplied with a low power consumption pump with variable speed control. e pump's interface enables you to select between 6 pressure levels with 2 types of controls:

• 3 constant pressure (CP) curves

• 3 proportional pressure (PP) curves

Constant Pressure Curve (CP) default setting. e circulator pump maintains the pressure level (head) constant as the system heat demand decreases (ow rate reduction). With these settings, the pump is suitable for all oor systems.

Setting procedure:

1) Factory setting Constant Pressure Curve CP3

2) Press the button for 10 seconds e pump goes into setting mode - the LED starts ashing

3) Each time it is pressed, the settings change LED “I”, “II”, and “III” are lit / the control curve and mode change

4) 10 seconds after the button is not pressed e setting is changed - the pump goes back to operating mode

5) LED “I” or “II” or “III” is still lit e pump is operating with the selected mode and curve.

voltar.com.ua

Proportional Pressure Curve (PP) is allows the pressure level (head) to be proportionally reduced as the system heat demand decreases (ow rate reduction). anks to this function, the electric power consumption of the circulator pump is reduced further: the energy (power) used by the pump decreases according to the pressure level and ow rate. With this setting, the pump guarantees optimal performance in most heating systems, proving particularly suitable in single-pipe and two-pipe installations.

25.1 AUDAX TOP 16 ErP PUMP SETTINGS AND CONFIGURATIONS

AUDAX TOP 16 ErP range boilers are supplied with a low power consumption pump with variable speed control. e pump's interface enables you to select between 6 pressure levels with 2 types of controls:

• 3 constant pressure (CP) curves

• 3 proportional pressure (PP) curves

Constant Pressure Curve (CP) default setting. e circulator pump maintains the pressure level (head) constant as the system heat demand decreases (ow rate reduction). With these settings, the pump is suitable for all oor systems.

Setting procedure:

1) Factory setting Constant Pressure Curve CP3

2) Press the button for 10 seconds e pump goes into setting mode - the LED starts ashing

3) Each time it is pressed, the settings change LED “I”, “II”, and “III” are lit / the control curve and mode change

4) 10 seconds after the button is not pressed e setting is changed - the pump goes back to operating mode

5) LED “I” or “II” or “III” is still lit e pump is operating with the selected mode and curve.

voltar.com.ua

Proportional Pressure Curve (PP) is allows the pressure level (head) to be proportionally reduced as the system heat demand decreases (ow rate reduction). anks to this function, the electric power consumption of the circulator pump is reduced further: the energy (power) used by the pump decreases according to the pressure level and ow rate. With this setting, the pump guarantees optimal performance in most heating systems, proving particularly suitable in single-pipe and two-pipe installations.

voltar.com.ua

TECHNICAL NOTE: System minimum water content:

To facilitate proper execution of the AUDAX TOP ErP heat pump defrost cycles, a minimum water content in the system is required, which must be: 6 l/kW of the machine's power for any type of system. e ywheel guarantees normal operation of AUDAX TOP ErP with systems divided into zones (with variable water content in circulation). e ywheel also guarantees proper operation with fan coils used for cooling (a condition in which the ow temperature is very low and has signicant heat load variations that vary the number of active fan coils). It is also important to check that the dehumidier line has a minimum of 3 l/kW of the machine (dehumidier hydraulic circuit connection). N.B.: for inertial tanks codes supplied by Immergas, refer to page 107.

TECHNICAL NOTE: System minimum water content:

To facilitate proper execution of the AUDAX TOP ErP heat pump defrost cycles, a minimum water content in the system is required, which must be: 6 l/kW of the machine's power for any type of system. e ywheel guarantees normal operation of AUDAX TOP ErP with systems divided into zones (with variable water content in circulation). e ywheel also guarantees proper operation with fan coils used for cooling (a condition in which the ow temperature is very low and has signicant heat load variations that vary the number of active fan coils). It is also important to check that the dehumidier line has a minimum of 3 l/kW of the machine (dehumidier hydraulic circuit connection).

AUDAX TOP ErP and Integrated System

41 SYSTEM MANAGER

It is an electronic controller with microprocessor, realised with the objective of being a "unique manager" for integrated systems. anks to this innovative supervisor, it is possible to establish and activate the most convenient heat source depending on functional, environmental and "economic" parameters.

voltar.com.ua

In fact, to control everything, the System manager must acquire

voltar.com.ua

the data relative to the external temperature (from the external probe) and the system ow temperature (relative to the pre-set climatic curve),after having congured the fuel cost parameter (e.g. methane gas) and that of the electric energy. Designed to enhance climatic comfort, it allows you to set dierent climatic curves for each zone, both for hot and cold. e user interface is made up from an LCD with matrix and a 6-key membrane keyboard. Installation takes place on a guide for electric components from control board.

voltar.com.ua

41.1 TECHNICAL FEATURES

Using the system manager (integrated with the relative expansion kits) it is possible to control:

• up to 4 AUDAX TOP ErP heat pumps in set conguration;

• Set the Tminimum integration (cut-o) or COP calculation to use the heat pump;

• Optimise the ow temperature to the system by means of probes situated on the secondary booster circuit (e.g. with a hydraulic manifold);

• In the event of boiler integration, it is also possible to keep AUDAX TOP ErP permanently active if COP is advantageous.

e Manager must be connected to the boiler via the external probe clamps (range models VICTRIX TT ErP, VICTRIX

kW TT, VICTRIX MAIOR TT, VICTRIX EXA, VICTRIX

voltar.com.ua

SUPERIOR ErP and all models with SUPERIOR electronics refer to the list in the previous page);

• DHW production boiler management via the heat pump as opposed to the solar system (AUDAX TOP ErP connected to

the lower coil, boiler connected to the upper coil), in order to obtain renewable source coverage on DHW;

• Option to have remote-domotic management on the Manager. 3 digital inputs are used on expansion address 5, which, according to their status (open/closed), determine the operation mode. Contact “domotic” management is executed using the following options:  Standby (inputs ID1=0 ID2=0 ID3=0);

→ Winter (inputs ID1=1 ID2=0 ID3=0); → Summer (inputs ID1=1 ID2=1 ID3=0); → Cooling (inputs ID1=0 ID2=0 ID3=1);

voltar.com.ua

→ Party (inputs ID1=1 ID2=0 ID3=1); → Digital output 4 regarding expansion address 5 is enabled

in the event of a system anomaly (for an error message to be sent to the domotic system);

• Input on expansion address 5 to force activation of AUDAX TOP ErP with the FV system, which generates electricity

(refer to the diagram on the next page). By using an inverter/ electronic device that supplies a signal when FV production exceeds a set value, a contact closes on expansion address 5, which:

→Immediately brings the DHW storage tank to 50 °C, disabling

any programmed DHW time bands;

→e minimum COP functional convenience is reset and

Tminimum integration brought to -15 °C, thus removing

voltar.com.ua

integration from the boiler; the only thing that remains active is the maximum time for the system to be fully operational, beyond which the boiler is activated in order to guarantee climatic comfort;

→If a puer system is congured in the menu, it is heated up

to 55 °C, even without request from the system; also in this case, the only thing to remain active is the maximum time for the system to be fully operational.

• Input on expansion address 4 to disable the generators (e.g. boiler or electrical resistance remain on standby) when a thermoue operates.

46 DEHUMIDIFIER

Designed to be coupled to cooling plants with radiant panels, the dehumidier allows to keep the percentage of relative humidity in the room within the comfort values, preventing the possible formation of condensate on the walls. e dehumidier, which is designed to be installed vertically on

voltar.com.ua

the wall (recessed), has pre- and post-cooling coils.

voltar.com.ua

ese components allow excellent control of the air temperature and humidity. However, it can function without the aid of pre and post cooling water coils, thus allowing to dehumidify when the cooling system is o, typical of mid-season. In compliance with European Directives, it has EC declaration of conformity.

Dehumidication can take place:

- with neutral air: without variation of the air temperature, dehumidies internal rooms;

- with cooled air:contributes to cooling the rooms, as well as reducing the internal relative humidity.

46.2 OPERATING PRINCIPLE

e humid air is taken from the room through the fan (7) and made to pass through the lter (1) and the pre-cooling water coil (2), where the air itself is cooled and taken to a condition near to the saturation curve. It then passes through the evaporating coil (3) where air is further cooled and dehumidied.

47 INTRODUCTION WITH COMMENTARY TO INTEGRATED SYSTEMS: MAIN APPLICATIONS

4848.1 Diagram with AUDAX TOP ErP and system distribution kit + DHW solar heating

System manager

Description of winter functioning:

- Central heating mode active  1 or more temperature/humidity sensors activate winter mode consent; the System Manager, according to the outdoor temperature detected and system's climatic curve and room temperature set for the various zones, activates AUDAX TOP ErP and (if COP is too low or if the temperature is not reached within the set time), the system's electrical resistance (via parameters that can be set with alternative or simultaneous operation).

- Domestic hot water mode  The System Manager, in addition operating the solar system, continuously monitors the set DHW temperature (probe located in the top part of the storage tank), enabling AUDAX TOP ErP and (if necessary) the electric resistance of the storage tank. The System manager will activate the integrative electric resistance of the storage tank only on request of the anti-legionella function and on reaching temperatures over 50 °C or if time required for making operational that is too long is considered.

voltar.com.ua

Description of winter functioning:

- Central heating mode active  Control Panel (standard) activates AUDAX TOP ErP in winter mode. Two dierent management options are possible to activate integrative electrical resistance, which are based on the outdoor temperature:

1) Switching the heat pump o and activating the auxiliary source (electrical resistance), if the outdoor temperature is below

2) Both the heat pump and electrical resistance are simultaneously activated if the outdoor temperature is between the 2 values

- DHW mode  when there is request for DHW, the system integrative resistance switches o and the 3-way valves divert onto the storage tank. AUDAX TOP ErP goes to the max temp. of 60 °C (compatible with the operating limits). e domestic hot water temperature is set on the solar control unit; if the set "setting" is greater than 50 °C, AUDAX TOP ErP heats the domestic hot water to 50 °C, the integrative resistance then switches on and the heat pump switches o.

Description of winter functioning:

- Central heating mode active  1 or more zone Controls activate winter mode consent; the system Manager, according to the outdoor temperature detected and the room temperature set above the pre-set climatic curve, activates AUDAX TOP ErP or the boiler according to the COP calculated (if > the minimum economical convenience value - use of AUDAX TOP ErP is approved), or according to Tminimum integration (cut o) set in the System Manager. Remember that also times for making the system operational can vary the boiler insertion mode.

- Domestic hot water mode this system was designed to privilege DHW operation of the boiler only, obviously in addition to the solar heating system (governed by the System Manager). During the summer cooling mode, the inversion of the AUDAX TOP ErP functioning cycle is also prevented (from chiller to heat pump).

5151.1 Diagram with AUDAX TOP ErP + boiler + 1 high temperature zone and system distribution

kit + solar heating for DHW + System Manager

Description of winter functioning:

- Central heating mode active  with respect to the previous layout, this system lets us have a simultaneous functioning variable of 1 high temperature zone and 2 low temperature zones. Substantially, we will have 3 cases:

1) Boiler serving a high temperature zone and AUDAX TOP ErP serving a low temperature zone.

2) Boiler serving a high temperature zone and low temperature zone.

3) AUDAX TOP ErP serving low temperature zones only. ese functioning modes are managed via appropriate positioning of the 2 x 2-way solenoid valves.

- DHW mode  if the Manager is connected to a boiler on the external probe clamps (refer to the list of provided models on page

71), the Heat Pump is activated if COP > COPmin / Toutdoor > Tminimum integration. At this point, if the set DHW is < 50 °C, AUDAX TOP ErP is active; however, if the set DHW is > 50 °C, AUDAX TOP ErP will heat water until it reaches 50 °C and then lets the boiler complete heating until the set value.

Description of winter functioning:

- Central heating mode active  the Control Panel and temperature/humidity sensor manage air conditioning of the 2 mac- ro-environments. Based on the outdoor temperature and room temperature detected and according to the set climatic curve, the System Manager activates AUDAX TOP ErP or the boiler COP calculated (if > minimum economical convenience value, use of AUDAX TOP ErP is appoved), or according to Tminimum integration (cut o) set in the System Manager.

- DHW mode  with this integrated system, the only source of renewable energy for DHW production is guaranteed from the heat pump. By means of the 3-way solenoid valve commutation between the system and storage tank, AUDAX TOP ErP is connected to the lower coil in the storage tank, thus guaranteeing central heating of a large amount of DHW (e.g: approximately 40 °C - in both winter and summer). Integration is guaranteed by the boiler, which is connected to both coils independently.

5353.1 Diagram with AUDAX TOP ErP (Summer/Winter air conditioning only) + boiler with

storage tank + DHW solar heating and separate central heating and cooling system - System Manager

Description of winter functioning:

- Central heating mode active  1 or more room thermostats, which act on the thermoelectric heads of the radiant system, enable a request in winter mode to the System Manager; this, in turn, based on the various parameters it is reading at that moment, enables AUDAX TOP ErP or the boiler if the calculated COP is lower than the minimum value of economical convenience. rough expansion "5", the System Manager controls the diverter valves, which commute with mode change (central heating/cooling).

Description of summer functioning:

- Cooling mode active  1 or more room thermostats, by acting on the fan-coils, enable a request in summer mode to the System Manager, which, in turn enables the heat pump.

voltar.com.ua

- Domestic hot water mode  In this specific case, domestic hot water production is managed by the boiler; the solar heating system, which is connected directly to the boiler, is also managed by the electronics of HERCULES SOLAR 200 CONDENSING ErP.

5454.1 Diagram with AUDAX TOP ErP in cascade (air conditioning only) + high-power boiler + thermal

ywheel and mixed zone + solar heating for D.H.W. production + System manager

Description of winter and summer operation:

- Central heating/cooling mode active  1 or more room thermostats, by acting on the apartment counters, enable a request to the expansion board that manages the upright column (mixed zone); the expansion board, in turn, sends the signal to the System Manager. Through a second expansion and an adjustable thermostat built into the storage tank, the Manager controls the temperature of the thermal flywheel in hot and cold. In this specific case, the temperature of the thermal flywheel, controlled by the thermostat, must have a greater offset (T. higher by 1-2 °C) than the relaunch mixed zone in winter, and a lower offset (T. lower by 1-2 °C) than the relaunch mixed zone in summer. Activation of the system (AUDAX TOP ErP rather than a gas generator) is, by standard, delegated by request from the thermostats and then the System Manager, which assesses the economic convenience or compares Toutdoor with Tminimum integration (cut o).

- Domestic hot water mode this system was designed to privilege DHW operation of the boiler only, obviously in addition to the solar heating system (governed by the System Manager along with the recirculation pump, through expansion "5").

NOTE: in this diagram, the Control Panel (standard with AUDAX TOP ErP) is not used.

- Central heating/cooling mode attiva  request from a room activates a central heating/cooling request via expansion in the hydraulic distribution kit, which, in turn, is connected via BUS to the system Manager. In the event of a cooling request via the diverter valve, the heat pump sends cooling fluid directly to the distribution kit. However, if central heating request is made, the distribution kit draws hot fluid from the combined storage tank. rough expansion "4" the System Manager also governs the 2 3-way valves that direct the hot uid coming from the heat pump or from the boiler towards the storage tank, based on the requests from probes "B13" and "B2".

- DHW mode  the system Manager controls the DHW from probe B2; the set-point to reach in B2 is connected to the DHW temperature requested + 10 °C. e system Manager activates AUDAX TOP ErP to bring the temperature in B2 to 50 °C, above which the integrative generator will be activated (in this case, the boiler).

NOTE: this diagram is an example. It is also required to convey the condensate drain of the heat pump and boiler.

In order to guarantee proper Heat Pump operation (also with antifreeze), each system must consider inserting a bypass to guarantee a minimum ow rate of 420 l/h. In this diagram, the bypass is already

installed in the zones kit (7).
