6.1 Installation instructions
Read this entire section before starting installation.
If changes or works have to be made on the house in-
stallation (e.g. extension, bypass of switch or socket
inserts) or the low-voltage distribution for mounting or
installing the accessory, the following safety instruction
must be considered:
Only to be installed by persons with the relevant
electro-technical knowledge and experience!*
Incorrect installation can put your own life at risk and the lives
of other users of the electrical system. Incorrect installation also
means that you are running the risk of serious damage to prop-
erty,e.g.becauseofare.Youmaybepersonallyliableinthe
event of injuries or damage to property. Contact an electrical
installer!
*Specialist knowledge required for installation:
The following specialist knowledge is particularly important
during installation:

12
Start-up
• The “5 safety rules” to be used: Disconnect from
mains; Safeguard from switching on again; Check that
system is de-energised; Earth and short circuit; Cover
orcordono󰀨neighbouringliveparts;
• Select suitable tools, measuring equipment and, if nec-
essary, personal safety equipment;
• Evaluation of measuring results;
• Selection of electrical installation material for safe-
guardingshut-o󰀨conditions;
• IP protection types;
• Installation of electrical installation material;
• Type of supply network (TN system, IT system, TT sys-
tem) and the resulting connecting conditions (classical
zero balancing, protective earthing, required additional
measures etc.).
The circuit to which the accessory and the load will be
connected has to be secured by a cable protection
switch in accordance with EN60898-1 (tripping charac-
teristic B or C, max. 16 A rated current, min. 6 kA inter-
rupting rating, energy limiting class 3). Installation regu-
lations according to VDE 0100 and HD382 or 60364
have to be considered. Users must be able to easily
access the cable protection switch. This must be
marked as disconnecting device for the actuator.

tion“ on page 5 during installation.

appropriate screwdriver and remove it (see gure 2+3).
Warning!
Disconnect from mains before removing the cover!
2. Connect the phase conductor to connecting terminal
L (C).
3. Connect the neutral conductor to connecting terminal
N (D).
4. Connect the protective conductor to connecting termi-
nal PE (E).
5. Connect e.g. the boiler to connecting terminal 1 (F) or
a circulation pump to the connecting terminals of the
switching channel 2 (G).
6. Push the latches of the cover into the openings provid-
ed and fasten the screws to close the cover.

app to enable operation of other DHC accessories with-
in your ecosystem. For further information, see the
manual of the DHC Access Point.
To integrate the DHC Basic IO Box into your ecosystem and
enable it to communicate with other accessories, you must con-
nect it to the DHC Access Point. To do so, proceed as follows:
1. Open the ONECTA app.
2. Click on the plus symbol.
3. Select the menu item Add Daikin Home Controls.
4. Select Add DHC Accessory.
5. Brieypressthesystembutton(A) (see gure 5).

Troubleshooting

7.1 Duty cycle
The wireless DHC accessories operate in the following frequen-
cy bands:
• 868,000~868,600 MHz
• 869,400~869,650 MHz
In order to safeguard operation of all devices working in this
range, it is legally required to limit the transmission time of de-
vices. Limiting the transmission time minimizes the risk of inter-
ference.
The ‘duty cycle’ is the maximum transmission time. It is the ratio
of the time that a device is actively transmitting in comparison
to the measurement period (1 hour), and is expressed as a per-
centage of 1 hour.
If the total amount of allowed transmission time is reached,
the DHC accessory will stop transmitting until the time limit is
reached.
For example, when a device has a duty cycle limit of 1%, it is
only allowed to transmit 36 seconds in 1 hour. After this, it will
stop transmitting until the 1 hour limit is reached.
DHC accessories fully comply to this limitation and use 2 fre-
quency bands with a duty cycle of respectively 1 % and 10%.
During normal operation of the DHC accessories, this limit is not
usually reached. However it is possible that the limit is reached
