5.6.9 Key for the application examples

Key for the hydraulic part
H1 Outdoor unit of the bi-bloc system (provide condensation drain on
the outdoor unit)
H2 Indoor unit of the bi-bloc system: In all models of the J and
H generation a strainer and a flow sensor form part of the scope of
delivery.
H2a Indoor unit (All in One unit) of the bi-bloc system: The All in One
unit includes a 200 litres domestic hot water tank, a tank tempera-
ture sensor, a 3-way valve and a hydrokit. The All in One unit must
be set up inside a building. In all models of the J and H generation,
a strainer and a flow sensor form part of the scope of delivery.
H2b Indoor unit (All in One unit in two-zone configuration ("B")) of the
bi-bloc system: The two-zone All in One unit ("B") with additional
equipment for a second heating circuit contains a 200 litres
domestic hot water tank, a tank temperature sensor, a 3-way valve,
a hydrokit, a mixing valve, a water circulation pump, a supply water
temperature sensor and a strainer for the additional mixed heating
circuit (in the "upper section"). The All in One unit must be set up
inside a building. In all models of the J and H generation, a strainer
and a flow sensor form part of the scope of delivery.
H3 The heat pumps are charged with R32 (J generation) or R410A
refrigerant (H generation). For all bi-bloc systems a maximum
connection distance and a maximum height difference between
indoor and outdoor unit applies, which is specified in the technical
data and must be observed. For all bi-bloc systems, the minimum
connection distance between indoor and outdoor units is 3 m.
H4 Magnetic filter (recommended)
H5 Filling and non-return valve
H6 Expansion vessel: Every heat pump has a 6 or 10 litres expansion
vessel that is designed for a total water capacity in the heating
system of 200 litres for an supply water temperature of 55 °C. For
any deviation from one of these conditions, another expansion
vessel must be provided on site.
H7 Electrical connections: Depending on hydraulic schematics and the
components to be controlled
H8 Overflow valve
H9 Optional thermostat: Every heating circuit can be controlled by an
optional thermostat, either by means of a room temperature sensor
or the remote controller (this can be used for one heating circuit
only).
H10 Buffer tank: The recommended total water capacity in the primary
circuit (when all heating/cooling circuits are closed), is at least
30 litres for systems up to and including 9 kW nominal heating
capacity (A7/W35), and at least 50 litres for systems with 12 and
16 kW nominal heating capacity (A7/W35).
H11 Heating/cooling circuit: If the heat pump is connected directly to the
heating system, the minimum water flow rate must be ensured at
all the times. For this purpose, an overflow valve (recommended
size: 1 inch) or a 3-way valve must be installed in the supply pipe
Aquarea air-to-water heat pumps - Planning and installation manual - 02/2022
to the room heating devices (fan coil unit, hide-away unit etc.) or a
heating thermostat must be removed to ensure a sufficient water
flow rate. For an underfloor heating, a safety thermostat must be
provided (for heating mode) and a dew point sensor (for cooling
mode).
H12 Optional PCB CZ-NS4P – required for this schematic
H13 Mixing valve with three point regulation
H14 Water pump for secondary circuit: The selection is to be made
depending on the requirements of the secondary circuit.
H15 Bivalent heat source
H16 Solar thermal system
H17 Solar pump
H18 Swimming pool pump
H19 Heat exchanger for swimming pool (to be dimensioned appropri-
ately)
H20 Swimming pool
H21 Expansion vessel (in fresh water supply)
H22 Sanitary facilities
H23 (only bi-bloc systems with hydrokit)
Optional circulation pump with timer switch
H23 (only bi-bloc systems with All in One unit)
For All in One units of the J and H generation, a safety valve (open-
ing pressure: 8 bar) is integrated in the domestic hot water tank.
H24 Domestic hot water tank: In the case of Panasonic domestic hot
water tanks, the tank temperature sensor is included in the scope
of delivery. When using third party tanks, one of the following
temperature sensors must be ordered separately from Panasonic:
CZ-TK1 (temperature sensor installation kit for third party tanks
with dip sleeve and 6 m long cable) or PAW-TS1 / PAW-TS2
(temperature sensor for third party tank with 6 or 20 m long cable).
As the hot water tank PAW-TG15C1EZ from Panasonic does not
have any circulation connection, the circulation pipeline must be
connected to the cold water entry pipeline when installing this tank.
H25 3-way changeover valve: As a 3-way valve, you can use either
a Panasonic CZ-NV1, which is installed inside the hydrokit, or
an external valve such as a Panasonic 3WYVLV-SI. The tank
temperature sensor must be ordered separately (see explanation
for H24).
