device, an auxiliary device or an alarm. The 2 inputs for
temperature probes can be used to measure the control
temperature, the evaporator temperature, products or aux
temperature, while the digital input can be programmed to carry
out various functions such as door opened signal, defrosting
commands, selecting a different set of temperature regulations,
external alarm signals, activating a continuous cycle, and activating
an auxiliary output etc.

1 - Key P
: Used for setting the Set point (press and release) and
for programming the function parameters
(hold pressed for 5 sec.)
In programming mode is used to enter in parameters edit mode and
confirm the values. In programming mode it can be used together
with the UP key to change the programming level of the
parameters.
When the keyboard is locked it can be used together with the UP
(hold pressed for 5 sec.) key to unlock the keyboard.
2 - Key DOWN/Aux
: In programming mode is used for decreasing
the values to be set and for selecting the parameters.
In normal
mode it can also be programmed via the parameter “t.Fb” to carry
out other functions (hold pressed for 1 sec.) such as activating the
Aux output, starting up the continuous cycle, etc. (see functions of
keys U and Down).
3 - Key UP/DEFROST
: In normal mode can be used to start/stop
manual defrosting (hold pressed for 5 sec.). In programming mode
is used for increasing the values to be set and for selecting the
parameters.
In programming mode can be used togetherwith key P
to change parameters level. Pressed together with the key P for 5
sec. allow the keyboard unlock
4 - Key U :
Used (press and release) for visualising the instrument
variables (measured temperatures etc.). In programming mode can
be used to come back in normal mode (hold for 2 sec.). In normal
mode it can also be programmed via the parameter “t.UF” to carry
out other functions (hold pressed for 1 sec.) such as turning on
and off (stand-by) the device, activating the Aux output, starting up
the continuous cycle, etc. (see functions of keys U and Down).
5 - Led SET
: In normal mode it serves to indicate when a key is
pressed. In programming mode indicates the programming level of
the parameters.
6 - Led OUT - COOL
: Indicates the output status (compressor or
temperature control device) when the istrument is programmed for
cooling operation; on (on), off (off) or inhibited (flashing).
7 - Led OUT - HEAT
: Indicates the output status (compressor or
temperature control device) when the istrument is programmed for
heating operation; on (on), off (off) or inhibited (flashing).
8 - Led DEFROST :
Indicates defrosting in progress (on) or
drainage time in progress (flashing)
9 - Led FAN :
Indicates fan output status on (on), off (off) or
delayed after defrosting (flashing)
10 - Led ALARM
: Indicates the alarm status (on), off (off) and
silenced or memorized (flashing)
11 - Led AUX
: Indicates AUX output status on (on), off (off) or
inhibited (flashing)
12 - Led Stand-By:
Indicate the Stand-by status.
2 - PROGRAMMING
2.1 -
FAST PROGRAMMING OF SET POINT
Press the key P then release it and the display will show
“SP
” (or
“SPE”
) alternating with the set value.
To change it press the UP key to increase the value or DOWN to
decrease it.
These keys increase or decrease the value one digit at a time, but
if the button is pressed for more than one second the value
increase or decreases rapidly, and after two seconds pressed, the
speed increases even more to all the desired valued to be reached
rapidly.
However, through par.
"t.Ed”
is possible to determine whether and
which Sets are set with the fast mode bybutton P.
The parameter is programmable with a value between oF and 4
which means that:
oF = Nothing is set with the key P (the P pressed and released has
no effect)
1 = can be adjusted only SP (normal)
2 = can be adjusted only SPE (economic)
3 = can be adjusted both SP and SPE
4 = can be adjusted the active set (SP or or SPE)
For example, if the parameter "t.Ed" = 1 or 3, the procedure is as
follows:
Press key P then release it and the display will show
"SP"
alternate
value.
To modify press key UP or DOWN to increase the value to
decrease.
If there is only the Set Point 1 ("t.Ed" = 1) once the desired value by
pressing the P button to exit the Set programming mode.
If is also programmable the EconomicSet Point ("t.Ed" = 3) by
pressing and releasing the P key again the display will show
"SPE"
alternate to the set value.
To modify press key UP or DOWN like Set “SP”.
When the desired value is set press the key P to exit from Set
Point programming mode.
Exiting the Set mode is achieved by pressing the P key or
automatically if no key is pressed for 10 seconds. After that time
the display returns to the normal function mode.
2.2 - STANDARD MODE PARAMETERS PROGRAMMING
To access the instrument’s function parameters when password
protection is disable, press the key
P
and keep it pressed for about
5 seconds, after which the display will visualised the code that
identifies the first parameter.
Using the UP and DOWN keys, the desired parameter can be
selected and pressing the P key, the display will alternately show
the parameter code and its setting that can be changed with the UP
and DOWN keys.
Once the desired value has been set, press the key P again: the
new value will be memorised and the display will show only the
code of the selected parameter.
Pressing the UP and DOWN keys, it is possible to select another
parameter and change it as described.
To exit the programming mode, do not press any key for about 30
seconds, or keep the U key pressed for 2 sec. until it exits the
programming mode.

2.3 - PARAMETER PROTECTION USING THE PASSWORD
The instrument has a parameter protection function using a
password that can be personalised, through the
“t.PP”
parameter.
If one wishes to have this protection, set the password number
desired in the parameter “t.PP”. When the protection is activate,
press the P key to access the parameters and keep it press for
about 5 seconds, after which the display will show
“r.P”
.
