Tab.1-1 Permissible combinations
Any other use outside the intended use is considered as improper.
The operator alone shall bear responsibility for any resulting damage.
Intended use also includes compliance with the maintenance and inspection conditions. Replacement parts must at least satisfy the
technical requirements defined by the manufacturer. This is the
case, for example, with original spare parts.
1.2.3 Device installation room
WARNING
The plastic wall of the storage tank on the indoor unit can
melt under the effects of external heat (>80 °C) and, in the
extreme case, can catch fire.
▪ Only install the indoor unit at a minimum clearance of
1m from other heat sources (>80°C) (e.g. electrical
heater, oil heater, chimney) and combustible materials.
CAUTION
▪ Only install the indoor unit if sufficient load-carrying ca-
pacity of the ground of 1050kg/m2 plus safety margin is
ensured. The ground must be flat, horizontal and level.
▪ Outdoor installation is not permissible.
▪ Installation in an explosion-risk environment is not per-
missible.
▪ The electronic control system must not be exposed to
whether effects like rain and snow under any circumstances.
▪ The storage tank may not be exposed to continuous
direct sunlight, as the UV radiation and the effects of
the weather will damage the plastic.
▪ The indoor unit must be installed protected from frost.
▪ Make sure that the supply company does not provide
corrosive domestic water. Suitable water treatment may
be required.
▪ Always ensure the minimum distances from walls and other ob-
jects (Chap. 3.3).
CAUTION
▪ If a DrainBack solar heating system is connected:
Install the indoor unit far enough under the solar panels
to allow complete emptying of the solar heating system.
(Follow instructions in the DrainBack solar heating sys-
tem manual). An insufficient height difference may lead
to destruction of the DrainBack solar heating system.
▪ The indoor unit must not be operated in rooms with am-
bient temperatures of more than 40°C.
CAUTION
▪ The required concentration may vary depending on the
type of glycol. ALWAYS compare the requirements
from the table above with the specifications provided by
the glycol manufacturer. If necessary, meet the require-
ments set by the glycol manufacturer.
▪ The added concentration of glycol must NEVER ex-
ceed 35%.
▪ If the fluid in the system is frozen, the pump CANNOT
start. Mind that if you only prevent the system from
bursting, the liquid inside might still freeze.
▪ If NO glycol has been added to the system and a power
failure or a pump failure occurs, drain the water from
the system.
▪ When the water inside the system is stationary, it can
easily freeze and thus damage the system.
CAUTION
Glycol absorbs water from its environment. Therefore do
NOT add glycol that has been exposed to air. Leaving the
cap off the glycol container causes the concentration of
water to increase. The glycol concentration is then lower
than assumed. As a result, the hydraulic components
might freeze up after all. Take preventive actions to ensure
a minimal exposure of the glycol to air.
Daikin Altherma ETS(X/H)(B)-D
Heat pump (indoor unit) with integrated heat accumulator
008.1448499_00 – 06/2019 – EN
CAUTION
Use only propylene glycol including the required inhibitors,
classified as categoryIII as per EN1717.
Installation manual

1 General safety precautions
CAUTION
▪ If overpressure occurs, the system releases some of
the fluid through the pressure relief valve. If glycol was
added to the system, take adequate measures so as to
safely recover it.
▪ Under all circumstances, make sure that the hose of
the pressure relief valve is ALWAYS free to release the
pressure. Prevent water from staying and/or freezing
up inside the hose.
1.2.4 Electrical installation
▪ Electrical installations may only be carried out by electrical techni-
cians and in compliance with valid electrical guidelines as well as
the specifications of the responsible energy supply company.
▪ Compare the mains voltage indicated on the nameplate with the
supply voltage before connecting to the mains.
▪ Before beginning work on live parts, disconnect them from the
power supply (switch off main switch, remove fuse) and secure
against unintentional restart.
▪ Device covers and service panels must be replaced as soon as
the work is completed.
1.2.5 Requirements for heating and storage water
Damage due to deposits and corrosion: observe the relevant technical rules to avoid corrosion products and deposits.
Minimum requirements regarding the quality of filling and top-up water:
▪ Water hardness (calcium and magnesium, calculated as calcium
carbonate): ≤3mmol/l
▪ Conductivity: ≤1500 (ideal: ≤100) μS/cm
▪ Chloride: ≤250mg/l
▪ Sulphate: ≤250mg/l
▪ pH value: 6.5 – 8.5
INFORMATION
To guarantee frost protection in the event of a power failure, glycol can be added to the heating water circuit.
Please observe the notes in Chap. 3.8.4.
Measures for desalination, softening or hardness stabilisation are
necessary if the filling and top-up water have a high total hardness
(>3mmol/l – total of the calcium and magnesium concentrations,
calculated as calcium carbonate). We recommend the use of Fernox
KSK limescale and corrosion protector. For other properties deviating from the minimum requirements, suitable conditioning measures
are necessary to maintain the required water quality.
Using filling water and top-up water which does not meet the stated
quality requirements can cause a considerably reduced service life
of the device. The responsibility for this lies solely with the operator.
1.2.6 Heating system and sanitary connection
▪ Create a heating system according to the safety requirements of
EN12828.
▪ The plumbing connection must comply with the requirements of
EN12897. The requirements of the following must also be observed:
▪ EN1717 – Protection against pollution of potable water installa-
tions and general requirements of devices to prevent pollution
by backflow
▪ EN61770 – Electric appliances connected to the water mains –
Avoidance of backsiphonage and failure of hose-sets
▪ EN806 – Specifications for installations inside buildings con-
veying water for human consumption
▪ and, in addition, the country-specific legislation.
When operating the indoor unit, the storage tank temperature may
exceed 65°C.
▪ For this reason, some form of scalding protection needs to be in-
cluded when you install the system (hot water mixing device, e.g.
VTA32).
If the indoor unit is connected to a heating system with steel pipes,
radiators or non-diffusion-proof floor heating pipes, sludge and chips
can enter the hot water storage tank and cause blockages, local
overheating or corrosion damage.
▪ To prevent possible damage, install a dirt filter or sludge separator
into the heating return flow of the system (SAS 1 or SAS 2).
▪ The dirt filter must be cleaned at regular intervals.
1.2.7 Operation
The indoor unit:
▪ Do not operate until all installation and connection work is com-
pleted.
▪ Only operate with a completely full storage tank (check level indic-
ator) and heating circuit.
▪ Operate at a maximum pressure of 3bar.
▪ Only connect with a pressure reducer on the external water supply
(supply line).
▪ Only operate if the protective cover is installed.
The specified servicing intervals should be adhered to and inspec-
tion work must be carried out.
1.3 Maintenance, troubleshooting and
decommissioning
Work for maintenance, troubleshooting and decommissioning must
not be carried out without knowledge of the relevant safety precautions and in the event of disposal of the country-specific guidelines.
Please refer to the corresponding information in the installer reference guide.
Recommendations for disposal
We designed the indoor unit in an environmentally friendly manner.
During the disposal process, the only waste created is that which
can be used for material or thermal recycling. The materials used
that are suitable for recycling can be sorted into individual types.
Thanks to the environmentally friendly design of the indoor unit, we have established requirements to ensure environmentally friendly disposal. Proper disposal in compliance with the
respective national regulations of the country of use is the responsibility of the user/owner.

3.6 Water connection
Important information
CAUTION
If the indoor unit is connected to a heating system with
steel pipes or radiators or non-diffusion-proof floor heating pipes, slurry and swarf could enter the hot water storage tank and cause blockages, local overheating or cor-
rosion damage.
▪ Rinse supply lines before filling the device.
▪ Rinse out the heat distribution network (in the existing
heating system).
▪ Install a dirt filter or sludge separator in the heating re-
turn flow (see Chap. 1.2.6).
CAUTION
If the indoor unit is connected to a cold water line where
steel pipes are used, chips can get into the stainless steel
corrugated pipe heat exchanger and remain there. This
can lead to contact corrosion damage and subsequently to
leakage.
▪ Flush the feed pipes before filling the heat exchanger.
▪ Install the dirt filter in the cold water supply (e.g. SAS 1
or SAS 2).
CAUTION: BIV ONLY
If the heat exchanger for pressurised solar system charging (see Chap. 3.1, items8 + 9) is connected to an ex-
ternal heater (e.g. wood-burning boiler), the indoor unit
can be damaged or destroyed due to an excessively high
inflow temperature at these connections.
▪ The inflow temperature of the external heater should
be limited to max. 95°C.
CAUTION
Corrosion may be caused by air entering the heating water
network and by a quality of the heating water that does not
comply with the requirements in accordance with
Chap. 1.2.5. Corrosion products (particles) thus created
may clog pumps and valves and cause malfunctions.
▪ Device may not be connected by permeable, flexible
lines.
▪ Install the indoor unit close to the withdrawal point to dispense
with the need for a circulation line. If a circulation line is mandatory, it must be installed according to the schematic diagrams in
"Hydraulic system connection" in the installer reference guide.
3.6.1 Connecting hydraulic lines
DANGER: RISK OF BURNING
There is a danger of scalding at hot water temperatures
over 65°C. This is possible when using solar energy if an
external heater is connected, the Legionella protection is
activated, or the target hot water temperature is set to be
greater than 65°C or if the Smart-Grid function is activated.
▪ Install scalding protection (hot water mixer device (e.g.
VTA32)).
INFORMATION
The indoor unit is equipped with a pressure sensor. The
system pressure in monitored electronically and can be
displayed with the device switched on.
Nevertheless, we recommend installing a mechanical pressure gauge between the indoor unit and the diaphragm expansion vessel, for example.
▪ Install the manometer so that it is easy to see when
filling.
Prerequisite: Optional accessories (e.g. solar, backup heater) are
mounted on the Daikin Altherma 3 H HT ECH2O as specified in the
enclosed instructions.
1 Check cold water pressure (maximum 6bar).
▪ If a higher pressure is present in the domestic water pipe, a
pressure reducer will need to be installed.
2 Make the hydraulic connections to the Daikin Altherma 3 H HT
ECH2O.
▪ Refer to Fig. 3-1 up to Fig. 3-4 and from Tab. 2-1 for the posi-
tion and dimensions of the heater connections and the outdoor
unit connections. The details of the hydraulic connection from
the indoor unit to the water inlet and outlet of the outdoor unit
can be seen in Fig. 3-29.
INFORMATION
In accordance with EN12828, a safety valve that limits the
maximum permissible operating pressure in the heating
system must be installed on or in the immediate vicinity of
the heat generator. There may not be any hydraulic blocking elements between the heat generator and the safety
valve.
Any steam or heating water that may escape must be
drained by a suitable blow-off line with constant gradient in
a frost-protected, safe and observable manner.
A diaphragm expansion vessel suitably sized and preset
for the heating system must be connected to the Daikin
Altherma 3 H HT ECH2O. There may not be any hydraulic
blocking elements between the heat generator and the diaphragm expansion vessel.
We recommend installing a mechanical pressure gauge for
filling the heating system.
▪ For potable water lines, observe the provisions of EN806,
DIN1988 and the additional applicable national regulations for
potable water installation.

phragm expansion vessel as per EN12828.
▪ Check the seat of the drain hose on the pressure relief valve.
▪ If necessary, connect and install a separate hose.
4 Carefully insulate pipework against heat loss and to avoid con-
densation (insulation thickness at least 20mm).
▪ Water shortage protection: the controller's pressure and tem-
perature monitoring function reliably shuts off the Daikin
Altherma 3 H HT ECH2O if there is a shortage of water. No additional water shortage protection is needed in the construction.
▪ Avoid damage caused by deposits and corrosion: see
Chap. 1.2.5
5 Connect the drain hose to the hose connecting piece for the
safety overflow (Fig. 2-3, item23).
▪ Use transparent drain hose (draining water must be visible).
▪ Connect the drain hose to an adequately dimensioned waste
water installation.
▪ Drain should not be lockable.

INFORMATION
If the heat pump outdoor unit is shut off via a circuit specified by the utility company, the indoor unit is not shut off.
3.7.6 Connecting the outside temperature sensor (optional)
The heat pump outdoor unit has an integrated outside temperature
sensor which is used for weather-compensated inflow temperature
control with frost protection function. The weather-compensated inflow temperature control can be further optimised with the optional
outside temperature sensor.
▪ Choose a location at about one third of the building height (min-
imum distance from floor: 2m) on the coldest side of the building
(north or north-east). Ensure that the location is not near any external heat sources (flues, air ducts), nor subject to direct solar radiation.
▪ Place outside temperature sensors in such a way that the cable
exit points face downwards (prevents the ingress of humidity).
CAUTION
Laying the sensor and mains lines in parallel within an installation conduit can lead to major malfunctions during
controlled operation of the indoor unit.
▪ Always lay the sensor line separately.
1 Connect the outside temperature sensor to a twin-core sensor
line (minimum diameter 1mm2).
2 Lay the sensor line to the indoor unit.
3 Follow the installation steps in Chap. 3.7.4.
4 Connect the sensor line to terminal strip XTA1 (see Chap. 3.7.2).
5 In the controller, RoCon+ HP set the [Outside temperature
sensor] parameter to "On" [→Main menu →Configuration
→Sensors].

INFORMATION
The [Heating support (HZU)] function integrated in the RoCon+ HP controller (see the controller operating instructions) makes it unnecessary to connect the EXT connection to the burner blocking contact connection of the solar
system.
3.7.8 EBA (external requirement request)
By connecting the EBA switching contact to the indoor unit
(Fig. 3-40) and corresponding parametrisation in its RoCon+ HP
controller, an external switching contact can be used to generate a
heat request. If the switching contact is closed, the indoor unit
switches to heating mode. The feed temperature is regulated to the
temperature set in the [Feed temperature, heating mode] parameter
[→Main menu →Configuration →Heating].
The EBA switching contact has priority over a request from the room
thermostat.
The switching contact is not evaluated in cooling mode, standby,
manual or summer mode. The heating limits are also ignored.
3.7.7 External switching contact
Connecting an external switching contact (Fig. 3-39) enables the operating mode of the indoor unit to be switched over.
The current operating mode is switched by a changing resistance
value (Tab. 3-3). The changeover of the operating mode is only effective for a long as the external switching contact is closed.
The operating mode has an effect on the direct circuit of the indoor
unit as well as all other heating circuits connected to this device as
an option.
When special functions (e.g. "Manual operation") are activated, the
input is not evaluated.

3.7.9 Connecting an external heat generator
INFORMATION
To connect an external heat generator, the connection set
for external heat generators must be installed (see
Chap. 3.5).
For heating support or as an alternative to an electric backup heater,
an external heat generator (e.g. gas- or oil-fired boiler) can be connected to the indoor unit. To connect an external heat generator, the
connection set for external heat generators must be installed (see
Chap. 3.5).
The heat supplied by the external heat generator must be fed to the
unpressurised storage tank water in the hot water storage tank of the
indoor unit.
Implement the hydraulic connection according to one of the two following options:
▪ unpressurised via the connections (solar inflow and solar re-
turn flow) of the hot water storage tank
▪ for ...bivalent indoor unit device types, via the integrated
pressurised solar heat exchanger.
▪ Comply with the instructions on hydraulic connections (see
Chap. 1.2)
▪ Examples of hydraulic connection (see "Hydraulic connection"
in the installer reference guide).
The external heat generator request is connected on PCB RTX-EHS
(see Fig. 3-41) via a relay. Electrical connection to the indoor unit is
possible as follows:
▪ External heat generator has a potential-free switching contact con-
nection for heat request:
▪ Connection to K3 if the external heat generator is responsible
for the domestic hot water preparation and the backup heating
(setting of the [Config. ext. heat source] parameter = DHW +
heating support [→Main menu →Settings →Ext. source])
or
▪ Connection to K1 and K3 if two external heat generators are

3.7.13 Connecting switching contacts (AUX outputs)
The switching contacts (AUX outputs) can be used for various parametrisable functions.
Switchover contact A-A1-A2 switches under the conditions set in
parameter [AUX switching function] [→Main menu →Settings →Inputs/Outputs] (see controller operating instructions).
3 Set-up and installation
Switchover contact A-A1-A2 can be used, for example, to control the
heat generators in bivalent heating systems consisting of an indoor
unit and an oil- or gas-fired boiler. Examples of hydraulic system integration are described in "Hydraulic connection" in the installer reference guide.
INFORMATION
If an A2F or G-plus condensing boiler is connected, the
[AUX switching function ] and [AUX wait time] parameters
must be set according to the desired function [→Main
menu →Settings →Inputs/Outputs].
See Controller operating instructions → chapter Parameter
settings.
Precise information on the electrical connection and the required parameter settings for such bivalent heating systems are available on the Internet (www.daikin.com) or
from your service partner.
3.7.14 Off-peak mains connection (HT/NT)
If the outdoor unit is connected to a low rate mains connection, the
potential-free switching contact S2S of the receiver, which evaluates
the low rate input signal output from the utility company must be connected to plug J8, EVU connection on the RoCon BM2C PCB (see
Fig. 3-46).
When setting the [HT/NT function] parameter > 0 [→Main menu
→Settings →Inputs/Outputs], certain system components are
switched off during peak periods (see controller operating instructions).
The following types of low rate mains connection are common:
▪ Type 1: With this type of low rate mains connection, the power
supply to the heat pump outdoor unit is not interrupted.
▪ Type 2: With this type of low rate mains connection, the power
supply to the heat pump outdoor unit is interrupted after a certain
period of time.
▪ Type 3: With this type of low rate mains connection, the power
supply to the heat pump outdoor unit is interrupted immediately.
Potential-free switching contact S2S can be implemented as a normally closed or normally open switching contact.
▪ If implemented as a normally closed switching contact, the [HT/NT
contact] parameter = 1 must be set [→Main menu →Settings
→Inputs/Outputs]. When the utility company sends the off-peak
signal, switching contact S2S is opened. The system switches to
"Mandatory OFF". If the signal is sent again, potential-free switching contact S2S closes and the system resumes operation.
▪ If implemented as a normally open switching contact, the [HT/NT
contact] parameter = 0 must be set [→Main menu →Settings
→Inputs/Outputs]. When the utility company sends the off-peak
signal, switching contact S2S is closed. The system switches to
"Mandatory OFF". If the signal is sent again, potential-free switching contact S2S opens and the system resumes operation.

3.7.15 Connecting an intelligent controller (Smart Grid - SG)
If the [Smart grid] parameter = 1, the function [→Main menu →Settings →Inputs/Outputs] is activated (see controller operating instructions), the heat pump is switched to normal or a mode with higher
temperatures depending on the utility company signal.
For this purpose, the SG1/SG2 floating switching contacts of the intelligent controller must be connected to the J8 connector, Smart
Grid and EVU connections on the RoCon BM2C PCB (see
Fig. 3-47).
As soon as the Smart Grid function is active, the HT/NT function is
automatically deactivated. Smart grid mode The heat pump is operated differently depending on the value of the parameter [→Main
menu →Settings →Inputs/Outputs] (see controller operating instructions).
CAUTION
Filling the storage tank with too high a water pressure or
too high a flow speed can cause damage to the indoor unit.
▪ Only fill with a water pressure <6bar and a flow speed
<15l/min.

valve from the combined filling and draining valve (Fig. 3-49,
item2).
3.8.4 Filling the heating system
DANGER: RISK OF ELECTROCUTION
During the filling process, water can escape from any leaking points and can cause an electric shock if it comes into
contact with live parts.
▪ Before the filling process, de-energise the indoor unit.
▪ After the first filling and before switching on the indoor
unit at the mains switch, check that all electric parts
and connection points are dry.
WARNING
Polluted domestic water is hazardous to health.
▪ When filling the heating system, make sure that heating
water cannot flow back into the domestic water pipe.

CAUTION
▪ The required concentration may vary depending on the
type of glycol. ALWAYS compare the requirements
from the table above with the specifications provided by
the glycol manufacturer. If necessary, meet the requirements set by the glycol manufacturer.
▪ The added concentration of glycol must NEVER ex-
ceed 35%.
▪ If the fluid in the system is frozen, the pump CANNOT
start. Mind that if you only prevent the system from
bursting, the liquid inside might still freeze.
▪ If NO glycol has been added to the system and a power
failure or a pump failure occurs, drain the water from
the system.
▪ When the water inside the system is stationary, it can
easily freeze and thus damage the system.

Protecting the water circuit against freezing
Frost can damage the system. To prevent the hydraulic components
from freezing, the software is equipped with special frost protection
functions, that include the activation of pump, internal heaters, and/
or backup heater operation in case of low temperatures.
However, in case of a power failure, these functions cannot guarantee protection. It is therefore recommended to add glycol to the water circuit. The required concentration depends on the lowest expected outdoor temperature, and on whether you want to protect the
system from bursting or from freezing. To prevent the system from
freezing, more glycol is required. Add glycol according to the table
below.
CAUTION
Use only propylene glycol including the required inhibitors,
classified as categoryIII as per EN1717.
CAUTION
Glycol absorbs water from its environment. Therefore do
NOT add glycol that has been exposed to air. Leaving the
cap off the glycol container causes the concentration of
water to increase. The glycol concentration is then lower
than assumed. As a result, the hydraulic components
might freeze up after all. Take preventive actions to ensure
a minimal exposure of the glycol to air.
CAUTION
▪ If overpressure occurs, the system releases some of
the fluid through the pressure relief valve. If glycol was
added to the system, take adequate measures so as to
safely recover it.
▪ Under all circumstances, make sure that the hose of
the pressure relief valve is ALWAYS free to release the
pressure. Prevent water from staying and/or freezing
up inside the hose.
INFORMATION
▪ Protection against bursting: the glycol protects the
pipes against bursting, but does NOT protect the fluid
in the pipes against freezing.
▪ Protection against freezing: the glycol protects the fluid
in the pipes against freezing.
