99 Unit not congured
7.2.4.3 Conguration method
Every HC-A16KNX can control up to 16 indoor units, considering that in the same H-LINK can be connected up to 160
indoor units, 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.
Id
Refrigerant cycle
address
Indoor unit address
00 00 00
01 00 01
02 00 02
03 00 03
04 00 04
05 00 05
06 00 06
07 00 07
08 00 08
09 00 09
10 00 10
11 00 11
12 00 12
13 00 13
14 12 02
15 25 61
NOTE:
• KNX software (ETS) is using indoor units from 1 to 16, corresponding to the ID from 0 to 15, so BMS is using indoor unit Id+1. For
example, in case you have 6 indoor units, declared as unit 1 to 6 on ETS, Ids have to be set from 0 (unit 1) to 5 (unit 6).
• It can be selected for 1 HC-A16KNX up to 16 indoor units from 16 different refrigerant cycles or 16 indoor units from the same refriger-
ant cycle.
CAUTION:
Be sure not to set same Indoor Unit to more than one HC-A16KNX. This error is undetectable and can cause undesired operations.
