MP2000 AIR CONDITIONERS

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

La base del regolatore, che rimane attaccata al muro, è provvista di morsettiera con innesti femmina per consentire il completo distacco della custodia che comprende la sonda di temperatura e tutti gli organi di impostazione.

Il regolatore è in grado di produrre due segnali analogici proporzionali 0⎟10V per il controllo del riscaldamento (Y10) e del raffreddamento (Y20).

Il set point di funzionamento è fisso a 21°C e può essere modificato agendo sulla manopola frontale "2" che consen- te una variazione di ±3°C con una risoluzione di 0,5°C.

Tramite gli innesti "3" è possibile limitare la rotazione della manopola frontale e, quindi, la modifica del set point. Posi- zionare i perni nei relativi fori con una leggera pressione.

Il selettore frontale "1" è attivo solo in riscaldamento e prevede tre livelli di selezione: Comfort-Economia-Standby.

-Comfort - set point 21°C - funzionamento diurno

-Economia - set point 15°C - funzionamento notturno

-Standby - set point 6°C - funzione antigelo.

La selezione Economia e Standby non è necessaria per il corretto funzionamento del sistema ma possono comun- que essere utilizzati a discrezione del Cliente.

Il commutatore "5" consente due tipi di impostazione:

-interruttore 1 - impostazione zona neutra per segnale raffreddamento: ON=2°C - OFF=4°C

-interruttore 2 - su posizione ON - non utilizzato

Il potenziometro "6" (Wi) consente la modifica di ±3°C del valore di set point in regime di Comfort (riscaldamento). Questa taratura può essere effettuata per compensare eventuali situazioni anomale quali il posizionamento del regolatore su una parete fredda.

Il potenziometro "7" (Yk min) consente di tarare il minimo del segnale di raffreddamento tra 0 e 7V (taratura di fabbrica 0V).

The regulator base, that is mounted on the wall, is equipped with terminals with female contacts, to allows the complete remove of the cover that includes the temperature sensor and the setting devices.

The regulator is able to make two 0⎟10V analog propor- tional signals for heating (Y10) and cooling (Y20) manage- ment.

The working set point is fixed at 21°C and, through the frontal handle "2", it is possible to change the value of ±3°C with 0,5°C resolution.

Through the pins "3" it is possible to limit the frontal handle rotation and, therefore, the set point modification. Insert the pins in the holes with a light pressure.

The frontal selector "1" is active only in heating mode and it foresees three selection levels: Comfort-Economy-Standby:

-Comfort - set point 21°C - day working

-Economy - set point 15°C - night working

-Standby - set point 6°C - antifreeze function.

The Economy-Standby selections is not necessary for the correct working of the system, but they can be utilized by the Customer according to his own needs.

The switch "5" allows two settings:

- switch 1 - neutral zone setting for cool signal: ON=2°C - OFF=4°C

- switch 2 - ON position - not used

The "6" potentiometer (Wi) allows a temperature set point adjustment of ±3°C in Comfort working mode (heating). This set allows an eventual compensation for particular installation of the regulator, such as the positioning on a cool wall.

The "7" potentiometer (Yk min) allows the minimum cooling signal setting from 0 to 7V (factory set 0V).
