Daikin Altherma EHS(X/H)
Daikin Solar tank with integrated interior heat pump unit
008.1420744 – 06/2015
3 x Set-up and installation
Internet gateway Daikin EHS157056
The controller can be connected to the internet via the optional
EHS157056 gateway. This means that the Daikin Altherma
EHS(X/H) can be controlled remotely via mobile phone (using an
App).
This component has a separate manual attached,
including among other things instructions for installation
and operation.
3.4.18 Connection of the Daikin FWXV(15/20)AVEB
This component has a separate manual attached,
including among other things instructions for installation
and operation.
Electrical connection of the
Daikin FWXV(15/20)AVEB with
the following accessories in accordance with fig. 3-32 as a
changeover contact (heating/cooling) on the basic module.
Connect genuine Daikin connecting cable (HPc-VK-1) to
Daikin Altherma EHS(X/H), so that the Daikin
FWXV(15/20)AVEB
switches the operating mode (heat-
ing/cooling) together with the Da
ikin Altherma EHS(X/H).
Install and connect 2-way valve (2UV) (HPC-RP) in the Daikin
FWXV(15/20)AVEB. Adjust its regulation so that the 2-way
valve (2UV) provides isolation if there is no demand for this
unit.
Mode (heating/cooling) can only be switched on the
Daikin Altherma EHS(X/H).

therma EHS(X/H)
3.4.19 Connection switch contacts (AUX outputs)
The switch contacts (AUX outputs) can be used for various dif-
ferent functions that can be parametrised.
If the Daikin Altherma EHS(X/H) is in the [Cooling] operating
mode, the switch contact B-B1 closes. The switch contact B-B1
is used for connecting an external status display ("Cooling mode
active"), for example.
The switching contact A-A1-A2 switches as configured in the pa-
rameter [AUX Fct] (see operating manual for the control unit).
Fig. 3-33 Connection switching contact (AUX output)
The relays to be used for Variant 2 (switched power > 15 W) must
be suitable for 100 % switch-on duration.
The switch-over contact A-A1-A2 can be used, for example, to
control the heat generator in bivalent heating systems of Daikin
Altherma EHS(X/H) and oil or gas boiler. Examples of the hy-
draulic system incorporation are shown in chapter 8.
3.4.20 Low tariff mains connection (HT/NT)
If the outdoor unit is connected to a reduced tariff mains con-
nection, the voltage-free switching contact S2S of the receiver
which evaluates the low tariff input signal emitted by the elec-
tricity supply company (EVU) must be connected to the pl
ug J8,
connection EVU on the RoCon BM1 circuit board
(see fig. 3-34).
When the Parameter [HT/NT Function] > 0 is set, certain
system components are switched off during peak tariff times
(see operating manual of the control unit).
The following types of reduced tariff mains connection are
stan
dard:
Type 1: With this type of low-tariff mains connection, the
power supply to the heat pump exterior unit is not discon-
nected.
Type 2: With this type of low-tariff mains connection, the
po
wer supply to the heat pump exterior unit is discon-
nected after a certain period of time.
Type 3: With this type of low-tariff mains connection, the
po
wer supply to the heat pump exterior unit is discon-
nected immediately.
The potential-free switching contact S2S can
be designed as a
normally-closed or a normally-open switching contact.
a) If it is designed as an open switching contact, then the
parameter [HT/NT Contact] = 1 must be set.
If the EVU transmits the reduced tariff signal, switching con-
tact S2S is opened. The system switches to
"Mandatory
OFF". If the signal is sent again, the potential-free switching
contact S2S closes and the system resumes operation.
