Note 1:
The minimum and maximum temperature records shall only be performed after the elapsing of
the alarm inhibition time when energizing the controller and after the delay in the instrument
energizing
[,F32]
+
[,F19]
.
Note 2:
The minimum and maximum temperature records shall only be performed after the compressor
reaches the active preset setpoint ; before that, the
[____]
messages will be displayed for the records
of minimum and
[++++]
for the records of maximum temperature.
7.3.7. Unit Selection
To select the temperature unit in which the instrument will operate enter the function

a)
Retract the lateral locks (Image VI - item 13);
b)
Remove the protective film from the adhesive side of the vinyl;
c)
Apply the vinyl over the whole top, folding the flaps, as indicated by the arrows - Image IX (item 13);
d)
Reinstall the latches.
Note:
The vinyl is transparent, allowing to visualize the electric scheme of the instrument.
7.3.3. Functions lockdown
The use of the functions lockdown brings greater security to the operation of the instrument. When it is
active, the setpoint and other parameters can be visible to the user, but are protected against undue
changes
or you can block changes of control functions and leave the adjustment of the

[OFF,]
will be
shown on the display indicating the deactivation of the lockdown
function when the key is released.
7.3.4. 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
[,F44]
. When enabled, the control and alarm functions are turned off
(
[CtrL][OFF,]
) or turned on (
[CtrL][On,,]
) through the menu provided in the option
[CtrL]
. When the control functions are switched off, the message
[OFF,]
will be displayed
alternately with the temperature and other messages. Control functions can be switched off / on by
pressing the key
;
for 5 seconds or by setting the
[,F35]
function - Digital input operation mode to
[,,,8]
- Digital input: To switch off the manual control, just touch the button (not supplied) connected
to the digital input to activate or deactivate this functionality.
Note:
When restarting the control functions, the times defined in the functions are counted, and these
delay the powering up of the instrument and the alarm inhibition time when switching on the controller.
7.3.5. Visualization of Processes
To view the process and the time elapsed, press
>
(quick touch) or by the
;
(Flatec) key pressing it
until the message
appears. This way, the controller will display the current process status, and
[Proc]
the following messages may appear on the display:
[dEL,]
- Initial delay (delay in the instrument start-up)
[rEFr]
- Cooling
[Hot,]
- Heating
[dEFr]
- Defrost
[drAi]
- Drainage
[----]
- Control functions off
Not
e:
If the function
[,F41]
- Display indication has been set to
[CooL]
or
[,USE]
, the message
of the process in progress will be displayed, the time elapsed from this process and then the message
[temp]
followed by the display of the measured temperature by the sensor, for a few seconds on the
display.
7.3.6. Minimum and Maximum Temperature Record
Pressing down the
<
key or also via the quick access menu (see chapter 6), will cause the message
[rE9,]
to be displayed, then the minimum and maximum temperatures recorded.
F
or erasing the current minimum and maximum values, hold down the
