Daikin Altherma EHS(X/H)
Daikin Altherma integrated solar unit
008.1420944 – 05/2014
2 Product description
2 x Product description
2.1 Brief description
The air-water heat pump system uses the physical effect of condensation and latent heat and makes it possible as required to
heat or cool buildings. The Daikin Altherma EHS(X/H) (Altherma
integrated solar unit) is the primary component of the highly-effi
cient heating- and cooling system for domestic applications.
Located in the external heat pump unit (ERLQ) are the coolant
compressor and a finned heat exchanger, which, in heating
mode, acts as a vaporiser and extract heat from the ambient air.
In cooling mode this acts as a condensator and returns heat to
the environment (refrigerator principle).
The heat pump external unit is connected to the heat pump internal unit in the building by means of a closed coolant circuit.
Heat or cold is transported between the heat pump external unit
and the heat pump internal unit by means of the circulating refrigerant, which alternately takes on the liquid and gaseous phases.
The internal heat pump unit contains the control devices, the heat
exchanger and integrated storage tank. In the heat exchanger,
the heat is transferred to the water flowing in the heating circuit or
the water in the storage tank (heating/hot water supply), or heat
is extracted from the water (cooling).
The storage tank on the Daikin Altherma EHS(X/H) is built in such
a way to enable the heat pump system to be combined with a
Daikin solar system without needing an additional hot water tank.
With optional solar heating, the entire hot water storage tank can
be heated, depending on the heat offered by the sun. The stored
heat is used both for hot water heating and for heating support.
The high total storage capacity also temporarily allows time
without sunshine to be bridged. The excellent heat insulation
properties of the integrated storage tank also ensure that heat
losses are kept to a minimum. This allows efficient and economic
water heating and also solar support.
If the heating capacity of the Altherma EHS(X/H) is not adequate,
the optional backup heater (EKBUxx) can provide additional
heating capacity for heating the heating circuit.
In order to make more cost effective use of the Daikin Altherma
EHS(X/H), it can be operated on a low tariff network connection
(HT/NT) or with an intelligent controller (SMART GRID). Here the
energy supply company (EVU) is afforded the opportunity to
control their network utilisation by changing the heat pump oper
ating mode. Information on the prerequisites and connection possibilities are described in the enclosed installation manual.
2.1.1 Mode of operation
In room heating mode the refrigerant which was compressed in
the refrigerant compressor in the heat pump external unit con
denses in the plate heat exchanger in the heat pump internal unit.
The heat released during the liquefaction of the coolant is trans-
ferred to the heating water in the plate heat exchanger. The heat
circulating pump ensures the required flow of the heating water in
the internal hear generation circuit.
The lower the required temperature in the heating circuit, the more effectively the heat pump works.
It is, in particular, possible to achieve the lowest flow
temperatures possible with under-floor heating, as the
heat transfer surface is very large. Furthermore, the
building to be heated should ideally have extremely
good heat insulation, so that when there is a low heat
requirement, the heat carrier can run with a low flow
temperature.
The hot water zone of the storage tank integrated into the interior
heat pump unit is heated by the heat pump or other external heat
generators (solar system, backup heater. The cold water flowing
downstream of the hot water extraction cools the lower area of
the integrated storage tank to maximum effect.
The drinking water is heated indirectly in a corrosion resistant
stainless steel corrugated pipe heat exchanger by the unpres
surised water from the integrated storage tank. On its way to the
top, it continuously absorbs the heat from the storage tank water.
The flow direction, operating on the principle of counter-flow, and
the coil-shaped heat exchanger create a pronounced temperature layering in the hot water storage tank. As high temperatures
can be maintained for a very long time in the upper section of the
storage tank, a high hot water output is achieved even if water is
drawn off over a long period of time.
In the case of room cooling the 3-way switching valves
(3UV1 + 3UVB) mounted on the heat pump internal unit switches
off the flow to storage tank charging/heating support. The heat
circulation pump of the heat pump internal device now operates
exclusively within the heating circuit.
The cooling process now takes place by inverting the heat pump
process in the heat pump external unit. Thus the heat exchanger
of the heat pump internal unit acts as a vaporiser and extracts
heat from the heating water that flows through it. This cools the
heating circuit.

2.1.2 Solar support
The Daikin Altherma EHS(X/H) is prepared for integration into a
Daikin solar system.
The pressureless Daikin Solar-System (Drain Back), and in
the case of Daikin Altherma EHS(X/H)B type systems the Daikin
Solar-Pressure system can be used.
The high performance flat collectors are highly effective in converting solar radiation into heat, which is transferred via the solar
circuit into the integrated storage tank of the Daikin Altherma
EHS(X/H).
The heat that is fed in is transferred to the hot water circuit. If
there are sufficiently high temperatures in the hot water tank the
solar heat is also used for heating support. The RoCon HP
control unit controls this heat distribution fully automatically.
2.1.3 Safety management
The total security management of the Daikin heat pump system
is assumed by the electronic control integrated in the Daikin Altherma EHS(X/H). In the event of a water shortage, loss of refrigerant or undefined operating states, a safety switch-off is performed. A corresponding fault signal provides an engineer with all
the necessary information for troubleshooting.
2.1.4 Electronic control
2.2 Design and components
2.2.1 System overview
Depending on the heating unit, the RoCon HP electronic digital
controller automatically controls all the heating, cooling and hot
water functions for a direct heating circuit, a storage tank
charging circuit and, using optionally connected mixer modules,
additional heating circuits as well.
All function settings for the Daikin Altherma EHS(X/H) and the optional equipment (terminal function) connected via the data bus
are performed by the operating elements of the RoCon B1 integrated into the controls and are displayed in clear text on a coloured backlit ground.
The display and operation of a connected Daikin solar system are
performed by the associated controller for this component (e.g.,
Control and Pump Unit EKSRPS3B).

3.1 General
DANGER!
If electrical components come into contact with water,
this can cause an electric shock as well as potentially
fatal injuries and burns.
● The displays and the buttons on the Controller
must be protected from the effects of moisture.
● To clean the Controller use a dry cotton cloth.
Using aggressive cleaning agents and other
liquids can cause damage to equipment or lead
to an electric shock.
Maximum energy utilisation
The most effective energy utilisation is achieved by the
Daikin Altherma EHS(X/H) at the lowest possible
return flow and hot water temperatures.
If an external heat generator (e.g. the optional Backup
Heater) is used at inflow target temperatures of over
50°C, the efficiency (COP) of the Daikin Altherma
EHS(X/H) can be affected negatively (depending on
the outside temperature).
3.2 Display and operating elements
3.2.1 Display
All the operating steps are supported by appropriate displays in a

The prerequisite for this function is that, in the level "Setup", the
parameter [Keylock Function] is set to "On" (see chapter 6.2.1,
tab. 6-1).
3.4 Basic functions and operating modes
If the storage temperature falls below a certain
minimum value, the safety settings of the Daikin
Altherma EHS(X/H) prevent the operation of the heat
pump in the case of low external temperatures:
– External temperature < -2 °C, minimum storage
temperature = 30 °C
– External temperature < 12 °C, minimum storage
temperature = 23 °C.
Without backup heater:
The storage tank water must be heated to the minimum
required storage temperature by an external heater.
With backup heater (EKBUxx):
With an outdoor temperature < 12 °C and a storage tank
temperature < 35 °C, the backup heater (EKBUxx) is
switched on automatically on in order to heat up the
storage tank water to at least 35
Automatic defrosting function
At low outdoor temperatures and corresponding humidity values,
the external heat pump unit may ice up. This icing impairs efficient operation. The system detects this condition automatically
and starts the defrosting function.
During the defrosting function, heat is drawn from the hot water
storage tank and the backup heater is turned on if required. De
pending on the heat demand for the defrosting function, heating
of the direct heating circuit may be interrupted temporarily.
After 8 minutes at most, the system returns to normal mode.

Displaying the water pressure
On the Controller RoCon HP, when it is switched on, you can
display the system pressure (water pressure) in the internal
circuit (direct heating circuit). The water pressure is available as
the first info parameter (see
The permissible range of water pressure during operation depends on the Daikin Altherma EHS(X/H) and the heating system.
The set values and threshold values must only be changed by the
heating technician. If the water pressure falls below the minimum
value (set parameter value), it must be increased by topping up
the system (see chapter on "Inspection and Maintenance").
fig. 3-6).
