Installation
&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-A32MB 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-A32MB 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-
A32MB and associated circuits.
Any unit that is not connected or is
not under power when turning on
HC-A32MB, will not be recognised

?Note:
– Offset Position is: 20000 + N*32 + Address as shown in table, where N is Indoor Unit position in address table.
– Status (real value) and set (set value) parameters have usually the same value but, in some cases, some of them can be
different. It is recommended to set parameters for normal control.

Operation
3.1.3 Conguration method
Every HC-A32MB can control up to 32 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-A32MB.
This conguration is not required in case of CHILLER application.
Setting concept consist in an “id” table listing up to 32 numbers for the assignation of each OU+IU addresses as shows the following
example:
Id Rerigerant cycle

Refer to the Service Manual of the corresponding indoor unit in order to know which is the meaning of the value showed in address
19. This value will be the same that the one showed on the RCS 7-segment.

Operation
?NOTE:
– It can be selected for 1 HC-A32MB up to 32 I.U from 16 different refrigerant cycles or 32 I.U from the same refrigerant cycle.
&CAUTION:
– Be sure not to set same Indoor Unit to more than one HC-A32MB. This error is undetectable and can cause undesired
operations.
