MP2000 AIR CONDITIONERS

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

SONDA DI TEMPERATURA NTC

Queste sonde sono impiegate per la misura della tempera- tura dell'aria e dell'acqua come di seguito indicato:

• Indicazione temperatura aria ambiente con sonda posta sulla ripresa aria condizionatore.

• Indicazione temperatura aria in mandata con sonda posta sulla mandata aria condizionatore (funzione limi- te).

• Indicazione temperatura aria esterna con sonda posta all'esterno, o sulla ripresa aria esterna condizionatore. Per le sonde poste esternamente all'unità è possibile aumentare la lunghezza fino a 100m max.

• Indicazione temperatura acqua con sonda posta sulle tubazioni di ingresso/uscita acqua refrigerata o calda.

NTC TEMPERATURE SENSOR

These sensors are used for the air and water temperature measurement as follows:

•Room air temperature indication with sensor placed on unit air intake.

•Air delivery temperature indication with sensor placed on unit air delivery (limit function).

•Fresh air temperature indication with sensor placed outdoor or on unit fresh air intake.

For sensor placed out of the unit it is possible to increase the cable length up to 100m max.

•Inlet/outlet water temperature indication with sensor placed on hydraulic pipes (hot water or chilled water).

NOTA: Separare quanto più possibile i percorsi dei cavi delle sonde dai cavi dei carichi induttivi e di potenza per evitare possibili disturbi elettromagnetici. Nel caso di distanze elevate è consigliabile utilizzare un cavo con doppio schermo o schermatura al 100% collegando lo schermo a terra solo lato unità.

NOTE: Please keep sensors leads as far as possible from power cables, to avoid possible electromagnetic noise.

In case of long distances, we suggest you to use a double shielded cable (100% shielded) with ground connection only on unit side.
