2.1. Safety Summary
&Caution
Do not connect voltage input to the control system before
installation is correctly done.
Read this manual carefully before performing installation
work.
 ReadthismanualinordertoconguretheHC-A16KNX
$Attention
Do not install HC-A16KNX in places... :
– with vapour, oil or dispersed liquids.
– with heat sources nearby (sulphuric surroundings).
– whereaccumulation,generationorleaksofinammable
gases has been detected.
– that are near the sea, in saline, acid or alkaline
surroundings.
$Attention
Install HC-A16KNX away from possible sources of
electromagnetic waves.
Respect local electrical standards.
Use a power circuit that is not subject to peak demands.
Ensure that there is enough free space around the HC-
A16KNX(seegure)sothattheheatmaydissipate
adequately (refer to “Installation
Work”).
If you install the HC-A16KNX in
vertical position, install the power
supply in the lower part and the
temperature control outputs in the
upper part
$Caution:
This appliance must be used only by adult and capable people, having received the technical information or instructions to
handle properly and safely this appliance.
Children should be supervised to ensure that they do not play with the appliance.

2.6. Installation procedure
Perform the following procedure:
1 Remove the rubber supports
2 Unscrew the 4 screws from the top cover and remove it
3 Attach the box to the rear vertical board from the inside with M4 screws (not provided) and place 3 mm washers on the outside to
separate the box from the wall.
4 Reinstall the top cover. Be careful to position it correctly.
&Caution:
- The signals’ cables should be as
short as possible. Keep a distance
of more than 150 mm from other
power cables. Don’t wire them
together (although they may
intersect). If they must necessarily
be installed together, take the
following measures to avoid noise:
- Protect the signal cable with a
metal tube which is earthed at
one end.
- For communications, use
shielded wire which is earthed at
one end.
%Danger:
- Always disconnect the power
supply for HC-A16KNX when
handling the machine, in order to
avoid eletrical discharges.
- Do not connect the interface to the
power supply until the installation
has been completed.
- Comply strictly with local security
codes and regulations when
connecting the machine to the
electric network.
- You will need a three-wire cable
(two cores and earth) with a
suitable plug at one end.
$Attention:
- Before applying power and turning
on HC-A16KNX you must ensure
that:
1. All circuits to be connected are
correctly applied.
2. All H-Link connections have
been set up.
3. Follow the local regulations for
the electrical installation of HC-
A16KNX and associated circuits.
Any unit that is not connected or is
not under power when turning on
HC-A16KNX, will not be recognised
andwillhavetobeconguredlater.
2.5. Servicing space
Keep free grated area for ventilation and cable connection.

3.3. Conguration Method
Every HC-A16KNX can control up to 16 I.U, considering that in the same H-LINK can be connected up to 160 IU, it must be set
which indoor units are selected for each HC-A16KNX.
Setting concept consist in an “id” table listing up to 16 numbers for the assignation of each OU+IU addresses as shows the following
example.
?NOTE:
– It can be selected for 1 HC-A16KNX up to 16 I.U from 16 different refrigerant cycles or 16 I.U from the same refrigerant cycle.
ThoseI.U.mustbeassignedtoaBMSidfrom0to15,from16to31mustbewithoutanyconguration.
&CAUTION:
– Be sure not to set same Indoor Unit to more than one HC-A16KNX. This error is undetectable and can cause undesired
operations.
– Addresses over id 15 are not used because they cannot be controlled with HC-A16KNX. Using them could create some
problemswiththeconguredunitsbetween0and15.

Nº ALARM CODE DESCRIPTION COUNTERMEASURE
1→61 Indoor Units have not communicated
with HC-A16KNX for more than 10
min.
1. Ensure that H-LINK connection is correctly done in
HARC (K1) and also Indoor Units
2. Ensure that Power are supplied to Air Conditioners
2→63 Indoor Units have never
communicated with HC-A16KNX
1. Ensure that H-LINK connection is correctly done in
HARC (K1) and also in Indoor Units
2. Ensure that Power are supplied to Air Conditioners
3D7 is always OFF No LED is ickering on PCB and 7
segments are OFF
1. Ensure that 230 are supplied to Power Source
2. Ensure that +5V DC is supplied to K3
?Notes:
- Power source output DC signal has a rotary switch
that must be correctly set to get +5V DC.
- D7 must be in ON
4 D12 is never ickering HC-A16KNX is not reading/sending
data (D12 is never ickering)
1. Check connection between MODBUS devices and
K5
5D13 is ickering HC-A16KNX is not operating
(D13 is ickering)
Check that KNX is connected and KNX power supply is
ON.
6D4 & D11 are not
ickering
There is no H-LINK communication
from HC-A16KNX
1. D4 is ickering but D11 is not ickering.
  See line Nº6, countermeasure 1
2. D4 neither D11 are not ickering.
 See line Nº1, countermeasure 1
