The need for address settings and the address setting range will differ according to the system configuration. (The address can-
not be set in duplicate).
(4) Setting the system controller address
(5) When using with master system controller
When connecting multiple system controllers, the system controller with many functions is designated as the "master", and the
system controllers with few functions are designated as the "slaves". The "master/slave" functions of the system controller used
together are as follows.
The functions have a priority in order of G50A (MJ-103MTRA) > PAC-SF44SRA > PAC-YT34STA > PAC-YT40ANRA > PAC-SC30GRA > LMAP02-E.
NOTE :
CAUTION
When the system remote controller is connected to the indoor and outdoor transmission line, the number of indoor units
that can be connected in that refrigerant system will be reduced by two.
When connecting the system controller to the indoor and outdoor transmission line, operations from the
system controller will be disabled if the outdoor unit's power is turned OFF, etc.

3 Configurations du système
(Reportez-vous au "Manuel de construction du système et de fonctionnement" pour plus de détails sur les unités externes.)
(1) En cas de connexion sur une conduite d'amenée de gestion centralisée
Un générateur (PAC-SC34KUA) est nécessaire.
* La puissance absorbée par le contrôleur à distance, la minuterie à emploi du temps et le contrôleur à distance de groupe est égale à la moitié de celle du con-
trôleur à distance ON/OFF. Vous devrez par conséquent considérer la puissance absorbée par chaque unité comme étant égale à la moitié de celle du contrôleur
à distance.

(2) En cas de connexion sur une conduite d'amenée interne et externe
Il est possible de connecter jusqu'à trois contrôleurs système sur une conduite d'amenée M-NET interne et externe.
L'utilisation d'un générateur n'est pas nécessaire dans ce cas, mais le connecteur de court-circuit d'une des unités externes
connectées doit être connecté au CN40.
(3) Réglages des différentes adresses M-NET
La nécessité d'effectuer le réglage des adresses ainsi que la plage de réglage des adresses varie en fonction de la configuration
du système. Il est impossible d’attribuer une même adresse deux fois.
(4) Réglage de l'adresse du contrôleur de système
(5) Utilisation avec un contrôleur de système maître
En cas de connexion de plusieurs composants du système, le rôle de "maître" est assumé par le contrôleur système ayant le
plus de fonctions, et celui d' "esclaves" par les contrôleurs ayant le moins de fonctions. Les fonctions "maître/esclave" du con-
trôleur système utilisées ensemble sont:
L'ordre des priorités est comme ceci: G50A (MJ-103MTRA) > PAC-SF44SRA > PAC-YT34STA > PAC-YT40ANRA > PAC-SC30GRA > LMAP02-E.

REMARQUE:

#
(1) Activation de la fonction d'interdiction de marche de contrôleur local depuis ce système
(mis à part le contrôleur à distance ON/OFF)
Lorsque vous connectez plusieurs contrôleurs système ensemble, et que vous réglez la fonction "interdiction du contrôleur à
distance local" à partir de ce contrôleur, réglez la fonction de ce contrôleur SW3-4 "commutation du réglage d’interdiction de
marche" sur "ON (autorisé)".
(2) Changement de l'affichage de la température réglée en "Degrés Fahrenheit"
(mis à part pour le contrôleur à distance ON/OFF)
Si vous souhaitez interdire un contrôleur système autre que celui-ci lorsque l’interdiction de contrôleur à distance local est
réglée depuis ce système, réglez le SW3-5 " commutation du réglage d’interdiction de marche" sur "ON (y compris le contrôleur
système)".
