INPUT/OUTPUT MENU

The input/output menu shows many of the values measured by the various probes

and transducers on the unit. You cannot set any values via this menu, but it gives

important operating information such as the defrosting status and so on.

NOTE: The top-left corner of each window shows which compressor is currently

providing the displayed data (U:1,2,3 o 4); to switch between compressors (only

possible from Master unit), refer to that explained in paragraph "3.3 Unit operating

status information (real time data) p. 7".

4.1 GENERAL STATUS OF INPUTS/OUTPUTS AND

COMPRESSORS

— Indicates to which compressor the displayed data refers (U:1 = Master; U:2 =

Slave 1; U:3 = Slave 2; U:4 = Slave 3)

— Actual water temperature value detected at unit inlet

— Actual water temperature value detected at unit outlet

— Status of compressor 1 and actual percentage load of use of the same; the com-

pressor status can be:

ok = indicates that the compressor è operating;

al = indicates that the compressor is stopped for alarm;

sp = indicates that the compressor is currently in "safety partialisation" mode;

F = indicates that the Freecooling mode is currently active;

WW = indicates that the compressor is currently in stand-by for safety differential;

PD = indicates that the compressor is currently in stand-by for pump-down;

--- = compressor not present;

— Status of compressor 2 and actual percentage load of use of the same; the com-

pressor status can be:

ok = indicates that the compressor è operating;

al = indicates that the compressor is stopped for alarm;

sp = indicates that the compressor is currently in "safety partialisation" mode;

F = indicates that the Freecooling mode is currently active;

WW = indicates that the compressor is currently in stand-by for safety differential;

PD = indicates that the compressor is currently in stand-by for pump-down;

--- = compressor not present;

— Status of compressor 2 and actual percentage load of use of the same; the com-

pressor status can be:

ok = indicates that the compressor è operating;

al = indicates that the compressor is stopped for alarm;

sp = indicates that the compressor is currently in "safety partialisation" mode;

F = indicates that the Freecooling mode is currently active;

WW = indicates that the compressor is currently in stand-by for safety differential;

PD = indicates that the compressor is currently in stand-by for pump-down;

--- = compressor not present;

— Status of compressor 1 and actual percentage load of use of the same; the com-

pressor status can be:

ok = indicates that the compressor è operating;

al = indicates that the compressor is stopped for alarm;

sp = indicates that the compressor is currently in "safety partialisation" mode;

F = indicates that the Freecooling mode is currently active;

WW = indicates that the compressor is currently in stand-by for safety differential;

PD = indicates that the compressor is currently in stand-by for pump-down;

--- = compressor not present;

— Each character of this string (starting from left) indicates the status of a digital

input; the first character indicates the status of ID1, the second of ID2, and so on

up to ID18 (O = open; C = closed)

— Each character of this string (starting from right) indicates the status of a digital

output; the first character indicates the status of C1, the second of C2, and so on

up to C18 (O = open; C = closed)

4.2 STATUS OF ANALOGUE INPUTS

— Indicates to which compressor the displayed data refers (U:1 = Master; U:2 =

Slave 1; U:3 = Slave 2; U:4 = Slave 3)

— Current pressure value measured on the high-pressure side of the refrigerant

circuit

— Current pressure value measured on the low-pressure side of the refrigerant

circuit

— This parameter may vary depending on the unit displayed:

TIA (B3) = Indicates the actual temperature value read at evaporator input (master

only);

TUAC (B3) = Indicates the actual temperature value read at common water outlet,

in case of outlet adjustment with multiple evaporators in parallel (only for Slave 1

unit);

— Indicates the actual temperature value read on the high pressure side of the

cooling circuit

— Indicates the current temperature value measured on the evaporator outlet

— Indicates the actual current value read at amperometric transformer input

— This parameter may vary depending on the unit displayed:

(B7) = Indica lo stato attuale dell'ingresso multifunzione (solo unità Master);

TUR (B7) = Indicates the actual temperature value read at recovery unit output (for

Slave units only);

— Indicates the current outside air temperature

— Indicates the actual temperature value read on the gas side at evaporator input

— Indicates the actual liquid temperature value

— Indicates the actual temperature value of the total recovery inlet water

— Indicates the actual temperature value of the total recovery outlet water

— Indicates the actual temperature value of the freecooling inlet water

— Indicates the actual temperature value of the freecooling outlet water

— Indicates the actual temperature value of the intermediate heat exchanger inlet

water

— B4 Exp: Not used

4.3 STATUS OF ANALOGUE OUTPUTS

— Indicates to which unit the displayed data refers (U:1 = Master; U:2 = Slave 1; U:3

= Slave 2; U:4 = Slave 3)

— Indicates the current voltage for the fan control
