7. Front Panel Commands

7.1 WHEN A CYCLE IS NOT ACTIVE.

SET:

TO DISPLAY SET POINT OF HOLD MODE:

by pressing and releasing this key when a freezing cycle is not active

the set point of the "Hold mode" is displayed for 5s.

TO MODIFY SET POINT OF HOLD MODE: by holding the key

pressed for at least 2s set point change mode is entered: the set point

is displayed and the LEDs of the first and third digits blink. To change

the value use the "UP" and "DOWN" keys. The new value can be

stored either by pressing the "SET" key (the instrument restores

temperature display) or by waiting the exit time-out to expire (15s).

(UP): To start a manual defrost: keep it pressed for 2s and a defrost

will start..

In programming mode or in "Function Menu" it browses the

parameter codes or increases the value of the displayed variable. Hold

pressed for a faster change.

(DOWN): TO ACTIVATE THE AUX RELAY: by holding the key

pressed for 3 s the AUX relay is activated. (The activation time

depends on the related parameter)

In programming mode or in "Function Menu" it browses the

parameter codes or decreases the value of the displayed variable.

Hold pressed for a faster change.

TO START (or STOP) A CYCLE: by pressing it the shown cycle is

started

, ...,

C1, ..., C4

To select and deselect a cycle: push one of these keys, the related

led will be lighted and the cycle will be selected. To select another

cycle push another key.

If no leds are on the holding phase is selected.

KEY COMBINATIONS

TO UNLOCK THE KEYBOARD: when held pressed for 3s the

keyboard is unlocked (see "LOC" function).

SET +

TO ENTER THE FUNCTION MENU: when a cycle is not active,

by holding these keys pressed for 3s the Function Menu is entered.

SET +

TO GO BACK TO THE PREVIOUSLY MENU Once entered in

the Function Menu or in some sub-menu, these keys can be used to

go to the previously menu.

7.2 WHEN A CYCLE IS ACTIVE

SET:

TO DISPLAY SET POINTS AND THE DURATION OF THE

CURRENT PHASE:

by pressing and releasing this key when a cycle is active the message

"rPS" room Probe Set is displayed followed by the flashing set point of

the room. While the set point is flashing press again the key and the

message "iPS" (insert Probe Set) will be displayed followed by the

value of the end phase temperature. Press again the SET key and the

remaining time of the phase will be displayed.

(UP): TO DISPLAY THE CURRENT PHASE: press and release the

UP key, the message PH1 (phase 1), or PH2 or PH3 or HP (hold

phase) will be displayed.

(DOWN): TO ACTIVATE THE AUX RELAY: by holding the key

pressed for 3s the AUX relay is activated only if OAC=AA

(anticondensation) or OAC= Li (light). (The activation time depends on

the related parameter)

TO TEMPORARILY STOP THE RUNNING CYCLE: press and release

this key, the running cycle will be stopped for the time set in the PAU

parameter, and the "Stb" flashing message will be diplayed.

TO MANUALLY STOP THE RUNNING CYCLE: keep pressing the key

until the "End" message will be displayed. The running cycle will be

definitively stopped.

8. How To Select A Cycle.

Assure that none cycle is active: the LED of the

Push one of the following keys C1, C2, C3, C4 the related led will be

lighted and the cycle will be selected.

NOTE: to pass from a cycle to another one simply push the related key.

symbol is OFF.

HOLD PHASE: To select the old phase deselect the enabled cycle

pushing the related key. ES. Cycle 1 is selected (its led is oon), push the

C1 key, the led will be turn off and the hold phase will be enabled.

Cycles are pre-set with the following values:

Cy1: for fast chilling and conservation of foods (hard +soft

chill).

Cy2: for chilling and fast freezing of foods (hard +soft +

freezing cycle).

Cy3: for direct fast freezing (only fast freezing cycle)

Cy4: for fast freezing avoiding ice skin (hard chill +

freezing cycle)

HLd: hold mode function

dEF: for starting a manual defrost

Now the cycle is memorised and can be activated.

9. How To Start The Selected Cycle.

Hold pressed the

10. How to temporarily stop the running cycle.

Press and release the

The compressor and the fan will be stopped for the PAU time (see

parameters list) and the flashing message "Stb" will be displayed.

To restart the cycle press and release the

from the some point at which it was interrupted.

In any case the cycle automatically restarts after the PAU time.

11. How to definitively stop the cycle.

Hold pressed the

the buzzer will be enabled.

The instrument is now placed in stand by mode.

12. How To Modify The Set Point Of The Hold Mode.

When a cycle is not active:

Hold the SET key pressed for at least 2s set point change mode is

entered: the set point of the hold mode is displayed and the LEDs of the

first and third digits blink.

To change the value use the "UP" and "DOWN" keys.

The new value can be stored either by pressing the "SET" key (the

instrument restores temperature display) or by waiting the exit time-out to

expire (15s).

13. How to start a manual defrost.

Assure that none cycle is active or the hold mode is running.

Hold press the UP key fro few seconds.

NOTE: The defrost will not be done if the temperature detected by the

evaporator probe is higher than EdF (stop defrost temperature) parameter. In

this case the "nod" message is displayed.

14. How A Cycle Is Done.

Every programmable cycle Cy1, Cy2, Cy3 or Cy4 can be divided into up

to 3 phases usually called:

•

hard chill

•

soft chill

•

freezing cycle

For each phase there are 3 parameters.

iS1, (iS 2, iS 3): Set point related to the third probe (insert probe) that

stops the current phase.

rS1, (rS2, rS3): set point of the room temperature for each phase.

Pd1, (Pd2, Pd3): the maximum duration time for each phase.

Hds : set point of the hold phase at the end of the whole cycle.

There are also 2 parameters related to the defrost. These are dbC = defrost

before cycle, dbH = defrost before holding (at the end of the cycle).

14.1 CONFIGURABLE CYCLE PARAMETERS

dbc (yes/no) Defrost before the cycle

iS1 (-50÷50°C;1°C/1°F) Insert Probe Set point: when the temperature

measured by the third probe reaches this value the first phase is ended.

rS1(-50÷50°C; 1°C/1°F) Room probe Set point for the first phase: it prevents

temperature from reaching a too low value during the hard cycle.

Pd1(OFF÷4.0h;10 min)Maximum time for first phase

iS2 (-50÷50°C; 1°C/1°F) Insert probe set point to end the second phase when

the temperature measured by the third probe reaches this value the

second phase is ended.
