WARNING: for installations requiring liquid-tight sealing, the cut-off for the installation of the
controller should be at must 70.5x29mm. The side latches must be secured so that they press
the rubber sealing to prevent infiltration between the cutout and the controller.
Vinyl protector - Image IX (item 13)
Protects the controller should when installed in a place with splashing water, such as in refrigerated
counters. This adhesive vinyl accompanies the instrument, on the packaging.
IMPORTANT: Apply only after completing electrical connections.
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.

6.3. Basic operations

6.3.1. Adjusting desired temperature (setpoint)
If configured not to use recipes (F03= [no,,]):
/
- Hold down the key for 2 seconds until the message [Set,]is displayed;
- Then the message [SP,,]will be displayed and the setpoint may be adjusted;
> <
- Use the or keys for changing the value, then press
If configured to use presets (F03=[Yes,]):
Each preset may be set up to use different values for the Setpoint, Control differential (hysteresis) and
Cooling time (interval between defrosts).
To select the preset:
/
- Hold down the key for 2 seconds until the message [Set,]is displayed;
- Then the currently selected preset will appear [Rc1,]or [Rc2,].
> <
- Use the or keys to select which of the 2 presets will be used.
/
- To confirm the selection, press .
Note: The values of functions Setpoint, Control differential (hysteresis) and Cooling time (interval
between defrosts) for each preset are set up in the parameters menu.
6.3.2. Manual defrost
The manual defrost is carried out through the quick access menu. Hold down the
until the message [dEFr]appears (flashing @LED), and then press the
a selection. Then the message [defr][On,,]will appear ( @LED on).
;
To turn off defrost manually press the key (quick touch) until the message [defr]appears (flashing

6.3.3. 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 (F36=2) or you can block changes of control functions and leave the adjustment of the setpoint
enabled (F36=1).
;
(short touch), access the function [LOC,] in the easy menu, confirm by pressing
Using the key
(short touch), then the message [no,,] will be displayed. After that keep the key
time configured for the functions lockdown (F37), until [LOC,] is displayed. The message [On,,]
will be displayed indicating the lockdown function is activated upon releasing the key.
To unlock, turn the controller off and then turn it on again with the key
until [LOC,] is displayed. Keep the key pressed for ten seconds and the message [OFF,] will be
shown on the display indicating the deactivation of the lockdown function when the key is released.

6.3.4. Control functions shutdown

The shutdown of the 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 disabled by the
shutdown function of the control functions (F38). When enabled, the control functions and alarms are
switched off ([CTRL][OFF,]) or on ([Ctrl][ON,,]) in the quick access menu through the
[Ctrl] option. When the control functions are off, the message [OFF,]is displayed alternating with
the temperature and other messages. Also is possible turn on/ turn off the control functions by pressing
;
the key for 5 seconds.
Note: By switched on again the control functions are counted the time defined in the instrument
energization delay and alarm inhibition time by temperature.

6.3.5. Visualization of Processes

To view the process and the time elapsed, press
[Proc]
until the message appears. This way, the controller will display the current process status, and
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

6.3.6. 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.
For erasing the current minimum and maximum values, hold down the
message [CrE9] is displayed, then the message [CodE] will appear; enter the value [,123],
/
then confirm with the key. If the code is correctly entered, the message [rSt,] will be displayed.
[rSt,]. This procedure keeps unauthorized users from erasing the minimum and maximum
temperature records.
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
[,F27] + [,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.
6.3.7. Unit Selection
To select the temperature unit in which the instrument will operate enter the function [,F01] using the
/
access code [,231] then press the . key. Then, select the unit desired[,=C,]or[,=F,] using
<> /
the keys; to confirm press . Every time the unit is changed, the functions settings return to the
default value, thus, they must be set up again.
6.3.8. Buzzer inhibition
When activated, the buzzer can be inhibited by pressing the
remain inhibited until a new alarm event takes place.
