9.4 Advanced Operations
9.4.1 Access to the main menu
The main menu can be accessed via the quick menu [Func] option or by pressing < and >(short
press) simultaneously during the temperature display.
The following options will be displayed:
[Code]- Access code input;
[Func]- Changing the parameters;
[Log,]- Datalogger configuration;
[ClO,]- Date and time adjustment;
[HACC]- Visualization of HACCP alarms.
9.4.2 Access code
To allow changing the parameters or setting the clock, enter the [Code] option by pressing / (short
press) and using the keys<or>enter the access code 123 (one hundred and twenty three), confirm
with /.
9.4.3 Amending the parameters of the controller
Within the main menu, select the option [Func] and select the desired function, using
the<or>keys. After selecting the function, press the/key (short press) to view its value. Use
the<or>keys to change the value and, when ready, press /to memorize the set value and return to
the function menu. To exit the menu and return to normal operation (temperature indication)
press/(long press) until[----]appears.
9.4.4 Internal datalogger
Datalogger configuration functions are available in the [Log,]menu.
With the datalogger enabled [F124] it is possible to make records in the controller's internal memory.
These records can be configured to be performed at time intervals [F125], by the variation of room
temperature S1 [F126] and/or by the variation in the state of the digital input or outputs [F127].
Enabling alarms also performs log recording. The information contained in a record is: temperature of
sensors S1, S2, S3 (if enabled) and S4 (if enabled), status of the control outputs, status of the door (if
digital input configured as a door contact), triggered alarms, record creation date and time.
Note: No records are made in the datalogger when the clock is not set.
9.4.5 Adjust the date and time
Within the main menu select the [ClO,]option, if the access code [,123] was entered correctly, the
controller enters the date and time setting mode. Use the<or>keys to change the value and, when
ready, press/ to memorize the set value. If the date entered is invalid, the message [ECLO] will
appear on the display. It is also possible to adjust the date and time through the easy menu (see item
9.3.8). In this case, it is not necessary to enter the access code.
9.4.6 HACCP
This controller assists the management systems of the food industries, allowing the monitoring of
critical points required by the HACCP (Hazard Analysis and Critical Control Points) regulation. Up to 24
records of the following types are stored: high temperature, low temperature, open door alarm and
power failure.
High temperature alarm [AlHi]
When, during operation, a temperature is identified above the value set in [F122] (HACCP - High
temperature alarm), remaining above this temperature for a time longer than the time set in F99
(Temperature alarm validation time), a record is created - [AlHi]type.
In this case, the information stored is: date and time of the start of the alarm, duration of the alarm and
maximum temperature measured during the alarm.

Low temperature alarm [AlLo]
When, during operation, a temperature lower than the value set in [F120] is identified (HACCP - Low
temperature alarm), remaining below this temperature for a time longer than the time set in [F100]
(Temperature alarm validation time), a record of type [AlLo]is created.
In this case, the information stored is: date and time of the start of the alarm, duration of the alarm and
minimum temperature value measured during the alarm.

Digital input alarm [AlIn]
When the open door alarm is enabled and activated, a[AlIn]recorded will be made. In this case, the
information stored is: date and time of the stard of the alarm, duration of the alarm and maximum
temperature measured during the alarm.
Power failure alarm [AlNo]
When there is a power failure and the controller is off for a period longer than 1 minute, when the power
returns and the controller has a temperature higher than the value set in [F122] (HACCP - High
temperature alarm), a record will be created immediately - [Alno]. In this case, the information
stored is: date and time of energy return and temperature value measured at the moment the controller
was turned back on.
Up to 6 records of each alarm type are stored. If the number of stored records exceeds this amount,
with each new alarm, the least recent record is replaced.
The visualization of the HACCP alarms must be done in the option [HACC] in the main menu or in the
easy menu (;). The [HACC] menu is subdivided according to the alarm type:
[ALHi]: where are the high temperature records;
[ALLo]: low temperature records;
[AlIn]: digital input records;
[Alno]: power outage records.
To view te records, follow the steps below:
a) Select the [HACC] option from the main menu and press /;
b) Choose the type of alarm to be displayed [ALHi], [ALLo], [AlIn] or [Alno] using the < or
> buttons and press/;
c) The controller stores up to 6 records of each type of alarm, use the < or > buttons to select the
record number you wish to view and press /;
Maximum Temperature Alarm
d) In alarms [AlHi], [ALLo] and [AlIn] the data will be displayed in sequence: date and time of
the start of the alarm ([,--d][,--m][,--y][00: 0 0]), alarm duration ([stay][00: 0 0]) and
maximum / minimum temperature measured during the alarm;
Setpoint
e) In[Alno] type alarms, the data will be displayed in sequence: date and time of the start of the alarm
([,--d][,--m][,--y][00: 0 0]) and temperature measured at the time of power return;
f) If there is no record stored in the chosen option, the message [,nop] will be displayed;
g) After displaying the alarm data, the controller returns to the HACCP alarms display menu.

Questions and answers
The temperature won't drop below 15 degrees F. Is there anything I can do? Also if I turn the control functions off will the compressor keep it frozen?
