6. MAIN FUNCTIONS

6.1 HOW TO SEE THE SETPOINT

Push and immediately release the SET key: the display will show the

Set point value;

6.2 HOW TO CHANGE THE SETPOINT

Push the SET key for more than 2 seconds to change the Set

point value;

The value of the set point will be displayed and the

blinking;

To change the Set value push the oor n arrows.

To memorise the new set point value push the SET key again or

wait 15s.

6.3 HOW TO START A MANUAL AGITATION CYCLE

Push the UP key for more than 2 seconds and a manual agitation

cycle will start.

6.4 HOW TO CHANGE A PARAMETER VALUE

To change the parameter's value operate as follows:

1. Enter the Programming mode by pressing the Set and UP key for

3s (

and

start blinking).

2. Select the required parameter.

3. Press the "SET" key to display its value (

4. Use "UP" or "DOWN" to change its value.

5. Press "SET" to store the new value and move to the following

parameter.

To exit: Press SET + UP or wait 15s without pressing a key.

NOTE: the set value is stored even when the procedure is exited by waiting the time-out to

expire.

6.5 THE HIDDEN MENU

The hidden menu Includes all the parameters of the instrument.

6.5.1 HOW TO ENTER THE HIDDEN MENU

1. Enter the Programming mode by pressing the Set + n key for 3s

(

and

start blinking).

2. When a parameter is displayed keep pressed the Set+n for more

than 7s. The Pr2 label will be displayed immediately followed from the

HY parameter. NOW YOU ARE IN THE HIDDEN MENU.

3. Select the required parameter.

4. Press the "SET" key to display its value (Now only the

blinking).

5. Use oor n to change its value.

6. Press "SET" to store the new value and move to the following parameter.

To exit: Press SET + oor wait 15s without pressing a key.

NOTE: the set value is stored even when the procedure is exited by waiting the time-out to

expire.

6.5.2 HOW TO MOVE A PARAMETER FROM THE HIDDEN MENU TO

THE FIRST LEVEL AND VICEVERSA.

Each parameter present in the HIDDEN MENU can be removed or put into "THE FIRST

LEVEL" (user level) by pressing "SET + n".

In HIDDEN MENU when a parameter is present in Fisrt Level the decimal point is on.

6.6 HOW TO LOCK THE KEYBOARD

Keep pressed for more than 3 s the UP and DOWN keys.

The "POF" message will be displayed and the keyboard will be locked. At this point it

will be possible only to see the set point or the MAX o Min temperature stored

If a key is pressed more than 3s the "POF" message will be displayed.

6.7 TO UNLOCK THE KEYBOARD

Keep pressed together for more than 3s the UP and DOWN keys.

7. LIST OF PARAMETERS

NOTE: the parameters preceded by dots usually are only in the Hidden Menu.

REGULATION

Hy Differential: (0,1 ÷ 25,5°C / 1÷255 °F) Intervention differential for set point.

Compressor Cut IN is Set Point Plus Differential (Hy). Compressor Cut OUT is when

the temperature reaches the set point.

•

LS Minimum set point: (- 50°C÷SET / -58°F÷SET): Sets the minimum acceptable

value for the set point.

•

US Maximum set point: (SET÷ 150°C / SET÷302°F). Set the maximum acceptable

value for set point.

Ot Thermostat probe calibration: (-12.0÷12.0°C;

-120÷120°F) allows the adjustment of possible offset of the thermostat probe.

•

OdS Outputs activation delay at start up: (0÷255min) This function is enabled at

the initial start up of the instrument and inhibits any output activation for the period of

LED starts

time set in the parameter.

AC Anti-short cycle delay: (0÷50 min) minimum interval between the compressor stop

and the following restart.

•

COn Compressor ON time with faulty probe: (0÷255 min) time during which the

compressor is active in case of faulty thermostat probe. With COn=0 compressor is

always OFF.

•

COF Compressor OFF time with faulty probe: (0÷255 min) time during which the

compressor is OFF in case of faulty thermostat probe. With COF=0 compressor is

always active.

DISPLAY

•

Temperature measurement unit: °C = Celsius; °F= Fahrenheit. WARNING:

When the measurement unit is changed the SET point and the values of the

parameters Hy, LS, US, Ot, ALU and ALL have to be checked and modified if

necessary).

rES Resolution (for °C): (in = 1°C; dE = 0.1 °C) allows the decimal point displaying.

AGITATION CYCLE

•

AgC Agitator configuration EL = switched ON and OFF with the compressor;

in = switched ON according to parameter IAg.

•

tiC Resolution for the Agt parameter

Pb = the Agt parameter is in seconds

iAG Interval between agitation cycles: (1÷120 min) Determines the time interval

between the beginning of two agitation cycles. NOTE: When a continuous agitation

cycle is started, the time counting is reset and starts from zero.

Agt Length for agitation cycle: (0÷255 min/sec) It sets the agitation cycle duration.

APO First agitation cycle after start-up: (y = Immediately; n= after the IAG time)

ALARMS

•

ALC Temperature alarms configuration: (Ab; rE)

Ab= absolute temperature: alarm temperature is given by the ALL or ALU values. rE

= temperature alarms are referred to the set point. Temperature alarm is enabled

when the temperature exceeds the "SET+ALU" or "SET-ALL" values.

ALU MAXIMUM temperature alarm: (ALL÷150°C;

ALL ÷302°F) when this temperature is reached the alarm is enabled, after the "ALd"

delay time.

ALL Minimum temperature alarm: (-50.0°C ÷ ALU;

-58°F ÷ ALU) when this temperature is reached the alarm is enabled, after the "ALd"

delay time.

LED is

•

ALd Temperature alarm delay: (0÷255 min) time interval between the detection of

an alarm condition and alarm signalling.

•

dAO Exclusion of temperature alarm at startup: (from 0.0 min to 23.5h) time

interval between the detection of the temperature alarm condition after instrument

power on and alarm signalling.

OTHER

•

PbC Probe selection: (Ptc=PTC probe; ntc=NTC probe). It allows the selection of

the type of probe.

•

rEL Software release for internal use.

•

Ptb Parameter table code: readable only.
