AUDAX TOP ErP and Integrated System

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.

5252.1 Diagram with AUDAX TOP ErP + boiler Plus + system distribution kit

+ DHW storage tank+ System manager

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.

- 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.

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