5.6.9 Key for the examples of use
Key for the Hydraulic Part
H1 Outdoor unit of the split system (provide condensation drain on
the outdoor unit)
H2 Indoor unit of the split system: In all models of the H series a
dirt catcher and an inflow flow meter form part of the scope of
delivery.
H2a Indoor unit (combination hydro-module) of the split system: The
combination hydro-module includes a 200 litres hot water tank,
a tank temperature sensor, a 3-way valve and a hydro module.
The combination hydro-module must be set up inside a building.
In all models of the H series, a dirt catcher and an inflow flow
meter form part of the scope of delivery.
H2b Indoor unit (combination hydro-module version "B") of the split
system: The combination hydro-module of version "B" with
additional fitting for a second heating circuit contains a 200
litres hot water tank, a tank temperature sensor, a 3-way valve,
a hydro-module, a mixing valve, a water circulation pump, an
inflow temperature sensor and a dirt catcher for the additional
mixed heating circuit (in the "upper section"). The combination
hydro-module must be set up inside a building. In all models of
the H series, a dirt catcher and an inflow flow meter form part of
the scope of delivery.
H3 The heat pumps are filled with a coolant R410A. For all split
systems (except systems with 3 and 5 kW), the maximum
connection distance is 30 m and the maximum height difference
between indoor and outdoor unit is 20 m. For all LT systems
(except systems with 3 and 5 kW), the maximum connection
distance is 15 m and the maximum height difference between
H20
indoor and outdoor unit is 5 m. For all heat pump systems, the
minimum connection distance between indoor and outdoor units
is 3 m.
H4 Magnetic filter (recommended)
H5 Fill- and non-return valve
H6 Expansion vessel: Every heat pump has a 10 litres expansion
vessel that is designed for a total water quantity in the heating
E39
system of 200 litres for an inflow temperature of 55 °C. For every
deviation from one of these provisions, another expansion vessel
must be provided on site.
H7 Electrical connections: Depending on hydraulic schematics and
E50
components to be controlled
H8 Overflow valve
E49
H9 Optional Thermostat: Every heating circuit can be controlled
by means of an optional thermostat, either by means of a room
temperature sensor or the operating unit (this can only be used
for one heating circuit).
E48
H10 Buffer tank / Volume expansion vessel: The recommended total
water quantity in the primary circuit (if all heating/ cooling circuits
are closed), for systems up to and including 9 kW nominal power
(A7/W35), is at least 30 litres and for systems with 12 and 16 kW
nominal power (A7/W35) it is at least 50 litres.
H11 Heating-/cooling circuit: If the heat pump is connected directly
to the heating system, the minimum water flow rate should be
ensured at all the times. For this purpose, an overflow valve

Planning
(recommended size: 1 inch) or a 3-way valve is installed in
the supply run to the room heating devices (fan coil, channel
device etc) or a heating thermostat must be removed to ensure
sufficient water flow rate. For an underfloor heating, a safety
thermostat must be provided (for heating mode) and a dew point
sensor (for the cooling mode).
H12 Optional additional PCB CZ-NS4P – required for this schematics
H13 Mixing valve with three point regulation
H14 Water pump for secondary circuit: The selection is made
depending on the requirements of the secondary circuit.
H15 Bivalent heat source
H16 Solar heat modules
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 domestic cold water inflow)
H22 Sanitary systems
H23 (only split systems with hydro-module)
Optional circulation pump with timer switch
H23 (only split systems with combination hydro-module)
For combination hydro-module of the H generation, a safety
valve (opening pressure 8 bar) is integrated into the hot water
tank.
H24 Hot water tank: In the case of Panasonic 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 (Tempera-
ture 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 hydro-module,
or an external valve such as a Panasonic 3WYVLV-SI.. The tank
temperature sensor must be ordered separately (see explanation
for H24).
