MP2000 AIR CONDITIONERS

Sistema di controllo a microprocessore per condizionatori d'aria • Air conditioners microprocessor control system

COLLEGAMENTO PER SISTEMA DI COMPENSAZIO- NE SET POINT TEMPERATURA

La connessione è a cura del Cliente; utilizzare un cavo

schermato ad 1 coppia intrecciata con sezione di 0,5 mm2 (tipo AWG20).

Collegamento per sistema di compensazione set point temperatura automatico (segnale in tensione).

Il segnale di compensazione proviene da un sistema ester- no (sonde attive o sistema di supervisione) e può essere collegato a più unità contemporaneamente.

In base al segnale installare le resistenze da 0,51W, non fornite, come indicato in figura e predisporre il ponticello J28 per l'ingresso B7 o il ponticello J29 per l'ingresso B8.

CONNECTION OF THE TEMPERATURE SET POINT COMPENSATION SYSTEM

Connection is by Customer care.

For this connection please use a single twisted-pair shielded cable with section of 0,5mm2 (type AWG20).

Connection for automatic temperature set point com- pensation (voltage signal).

The compensation signal coming from an external system (active sensor or supervision system) and it is possible a multipoint connection with more units.

According to the signal type install two 0,51W resistances, not furnished, as shown in the picture and predisposition of the J28 jumper, for inlet B7, or J29 jumper for inlet B8.
