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;

Push and immediately release the SET key or wait for 5 seconds to display

the probe value again.

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

To change the Set value push the o or n arrows within 10s.

To memorise the new set point value push the SET key again or wait 10s.

6.3 HOW TO START A MANUAL DEFROST

Push the DEF key for more than 2 seconds and a manual

defrost will start.

6.4 HOW TO SWITCH ON OR OFF THE SECOND RELAY

(OAC= LHt)

Hold pressed the n key for some seconds, till the AUX LED is

turned ON or OFF

6.5 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

DOWN key for 3s (

2. Select the required parameter.

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

LED is blinking).

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.

6.6 THE HIDDEN MENU

The hidden menu Includes all the parameters of the instrument.

6.6.1 HOW TO ENTER THE HIDDEN MENU

1. Enter the Programming mode by pressing the Set + n

key for 3s (LED 1 and

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

5. Use o or n to change its value.

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

To exit: Press SET + o 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.

6.6.2 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 First Level the decimal point is

on.

6.7 HOW TO LOCK THE KEYBOARD

Keep pressed for more than 3 s the o and n 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.

6.8 TO UNLOCK THE KEYBOARD

Keep pressed together for more than 3s the o and n keys, till the "Pon"

message will be displayed.

6.9 THE CONTINUOUS CYCLE

When defrost is not in progress, it can be activated by

holding the "o" key pressed for about 3 seconds.

The compressor operates in continuous mode for the time set through the "CCt"

parameter. The cycle can be terminated before the end of the set time using the

same activation key "o" for 3 seconds.

7. PARAMETERS

NOTE: the parameters preceded by dots are 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.



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

acceptable value for the set point.



US Maximum set point: (SET÷110°C/ SET÷230°F). Set the maximum

acceptable value for set point.

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

-120÷120°F) allows to adjust 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 time set in the parameter.

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

compressor stop and the following restart.



CCt Compressor ON time during continuous

10min) Allows to set the length of the continuous cycle: compressor stays on

without interruption for the CCt time. Can be used, for instance, when the

room is filled with new products.



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.

CH Type of action: CL = cooling; Ht = heating.

DISPLAY



CF 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 decimal point display.

DEFROST

IdF Interval between defrost cycles: (0÷120h) Determines the time interval

between the beginning of two defrost cycles.

MdF (Maximum) length for defrost: (0÷255min) When P2P = n, (not evaporator

probe: timed defrost) it sets the defrost duration, when P2P = y (defrost end

based on temperature) it sets the maximum length for defrost.



dFd Temperature displayed during defrost: (rt = real temperature; it =

temperature at defrost start; SEt = set point; dEF = "dEF" label)



dAd MAX display delay after defrost: (0÷255min). Sets the maximum time

between the end of defrost and the restarting of the real room temperature

display.

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: (SET÷110°C; SET÷230°F) when this

temperature is reached the alarm is enabled, after the "ALd" delay time.

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

-58÷230°F when this temperature is reached the alarm is enabled, after the

"ALd" delay time.



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.

SECOND RELAY AND DIGITAL INPUT (IF AVAILABLE)



tbA

Alarm relay silencing (with oAC=ALr):

(n= silencing disabled: alarm relay stays on till alarm condition lasts, y

=silencing enabled: alarm relay is switched OFF by pressing a key during an

alarm).

OA1 Second relay configuration: ALr: alarm; LHt: auxiliary; onF: always on;

dEF: do not select it!.; FAn: do not select it!.;

AoP Alarm relay polarity: it set if the alarm relay is open or closed when an alarm

happens. CL= the relay is closed; oP = the relay is open

i1P Digital input polarity: oP: the digital input is activated by opening the

contact; CL: the digital input is activated by closing the contact.

i1F Digital input configuration: EAL = external alarm: "EA" message is

displayed; bAL = serious alarm "CA" message is displayed. PAL = pressure

switch alarm, "CA" message is displayed; dor = door switch function; dEF =

activation of a defrost cycle; LHt =switch on the second relay if oA1=LHt; Htr =

kind of action inversion (cooling – heating).

did: (0255 min)

with i1F= EAL or i1F = bAL digital input alarm delay: delay between the

detection of the external alarm condition and its signalling.

with i1F= dor: door open signalling delay

with i1F = PAL: time for pressure switch function: time interval to

calculate the number of the pressure switch activation.

nPS Pressure switch number: (0

switch, during the "did" interval, before signalling the alarm event (I2F= PAL).

If the nPS activation in the did time is reached, switch off and on the

instrument to restart normal regulation.
