9.3 Basic operation
9.3.1 Desired Temperature Adjustment (setpoint)
To enter the setpoint adjustment menu, press / for 2 seconds. The message [,,SP] will appear on
the display, followed by the value for adjusting the normal setpoint. Use the < or >keys to modify the
value and confirm by pressing /. Then the message indicating [SP-E] the economic setpoint
adjustment will be displayed. Again, use the <or> keys to modify the value and confirm by pressing
/. Finally, the indication [----] signals the completion of the configuration. Setpoints can also be
changed individually in the access menu.
9.3.2 Economic setpoint (SPE)
[SP-E] provides greater savings to the system by using more flexible parameters for temperature
control.
When it is active, the message [,ECO] starts to be displayed alternating with the temperature and the
other messages.
Economy mode can be activated or deactivated using the commands:

9.3.3 Manual defrost
The defrost process can be activated / deactivated manually through the easy menu in the [dEFr]
option or by pressing the < key for 4 seconds or using the external key connected to the digital input.
Activation or deactivation is indicated by the message [dEFr] [On,,] or [dEFr] [OFF,],
respectively.
9.3.4 How to determine when defrosting is complete using the
temperature
a) Set the condition for starting defrosting as based on time, [F19] = 1 ;
b) Reset the functions related to the end of defrosting to their maximum value:
- Refrigeration time (interval between defrosting periods) [F20] = 9999min;
- Temperature of the Evaporator to finish the defrost [F39] = 105°C / 221°F;
- Maximum time on defrost (for safety) [F41] = 999min.
c) Wait a while until a layer of ice has formed on the evaporator;
d) Defrost manually (using the key ; advance to [dEFr] and press / or press the < key for 4
seconds);
e) Visually monitor the melting;
f) Wait until all the ice on the evaporator has melted to determine when the defrosting is over;
g) With the defrost completed, check the temperature in the evaporator (S2) using the >key (see item
9.3.13);
h) Using the reading for S2, adjust the temperature to end the defrosting;
- Evaporator temperature to end defrost [F39] = Temp S2.
i) As a safety measure, reset the maximum defrost duration, according to the type of defrosting set;
Example:
- Electric defrost (by resistors) [F41] = 45 min;
- Hot gas defrost [F41] = 20min.
j) Finally, adjust the refrigeration time (Interval between defrosts) [F20] to the desired value.
9.3.5 Defrost with two evaporators
With S3 configured for the 2nd evaporator sensor [F60], the FAN output gives rise to the control of the
second resistor. Defrost always starts with both outputs activated. The resistors are turned off
individually as their evaporators reach the temperature for defrosting. With both outputs off or after the
maximum defrost time has elapsed, the draining process starts.
Note 1: With these settings, all FAN output functionalities are disregarded, including the Fan Delay
process.
Note 2: Defrosting with two evaporators using the FAN output does not prevent the use of the variable
speed fan (VSF). In this case, the fan speed is calculated in relation to the sensor with the highest
temperature (to limit the inflow of hot air).
9.3.6 Fast Freezing
In fast freezing mode, the refrigeration output is permanently on and therefore the refrigeration or
freezing process is accelerated. This operating mode can be activated or deactivated in the easy menu,
in the [FASt] option or through an external switch connected to the digital input. It can also be
deactivated automatically by temperature ([F15]) or by time ([F16]). While fast freezing is on, the
connected compresor display will flash rapidly and defrosting will continue. If, on activating the fast
freezing mode, the controller identifies that there is a defrost cycle programmed to start during this
period of time, the defrost will be run first and then it will go into fast freezing mode.
9.3.7 Turning the lamp on/off
Through the menu facilitated in the option [Lamp]or by pressing the key >(short press) it is possible
to turn the lamp on/off manually if the AUX output is configured as a lamp ([F89]=1) and the defrosting
of the tray is not configured to use the AUX output ([F43]=2)
Note: When switching on the lamp manually, the time for when the lamp will be switched off after
the door is closed [F64] will be reset.
9.3.8 Adjust the date and time
The date and time can be adjusted using option [ClO,]from the access menu. This option is
accessed with the ;key (Flatec) and confirmed with the /key.
In the date and time setting mode, use the keys<or>to change the value and, when ready, press/ to
memorize the configured value. If the date entered is invalid, the message [ECLO] will appear on the
display.

9.3.9 View current time and dates
By briefly pressing the /key (short press) you can view the date and time set on the controller. The
current day ([,--d]),month ([,--m]), year ([,--y]), day of the week ([day-]), hour and
minutes will be shown in sequence on the display ([00: 0 0]).
Note: The controller leaves the factory with the clock disabled. To enable it follow the directions in item
9.3.8
Example:[day1] equals Sunday.
9.3.10 Manual activation of the datalogger
Manual activation of the internal record of temperature values and status of the control outputs
(Datalogger) is performed through the facilitated menu in the option [dtl,]. The message [dtL,]
will be displayed followed by the message [On,,] for when the datalogger is activated or [OFF,]
for when it is deactivated.
Note: For correct operation of the datalogger it is necessary to adjust the clock. See item 9.3.8
9.3.11 Function Lock
The function lock provides more security when using this device. When it is enabled the normal and
economic setpoints and other parameters can be viewed, but are not able to be changed ([f139]=2)
or you can just lock the device against changes to the control functions but allow the normal and
economic setpoints be amendable ([f139]=1). To lock the functions, access the option [LOC,] in
the easy menu using the key ;(Flatec) and confirm by pressing the /key. The message [no,,] will
be displayedif the lock is disabled. Now press and hold the > key for the time configured for this
function [f140].
Activation will be indicated by the message [LOC,][On,,]and will only occur if function[f139] is
set to 1 or 2. To deactivate the lock, turn off the controller and turn it on again with the > key pressed.
Keep the key pressed until the message [LOC,][OFF,] indicates that it has been unlocked (10
seconds).
Note: The date and time adjustment will always be enabled, regardless of the values of [F139] and
[F140].
9.3.12 Shutdown of Control Functions
Turning off control functions allows the controller to operate only as a temperature indicator, keeping
the control outputs and alarms off. The use of this feature is enabled or not by the Shutdown of Control
Functions feature [F141]. When enabled, the control and alarm functions are turned off
([CTRL][OFF,]) or turned on ([Ctrl][ON,,]) using the menu provided by the option
[Ctrl]. When the control functions are turned off, the message [OFF,]will be displayed,
alternating with the temperature and other messages. It is also possible to switch off and on the control
functions by pressing the ; key for 5 seconds.
9.3.13 Process stage, elapsed time, temperature on sensors
S2/S3/S4 and current setpoint
The controller's operating status can be viewed by pressing the > key (4 seconds). A sequence of
messages will be displayed indicating the current process, the time (hh:mm) already elapsed in this
stage and the temperatures in sensors S2, S3, S4 and the current setpoint (normal or economic). If any
sensor is disabled, its measurement will not be displayed.
Process stages:
[dEL,]- Initial Delay (delay in starting up the instrument);
[rEFr]- Refrigeration;
[Hot,]- Heating;
[Pre,]- Pre-Defrost;
[dEFr]- Defrost;
[dRAi]- Drainage;
