1.
Key:
Used to change the Set Point (press and release)
and to program the function parameters (pressed for 5 s).
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 key to change the pro-
gramming level of the parameters. When the keyboard is
locked it can be used together with the (hold pressed
for 5 s) key to unlock the keyboard.
2.
/Aux Key:
In programming mode is used for decreas-
ing the values to be set and for selecting the parameters.
Hold pressed for 1 s, while in normal mode, it can also be
programmed via parameter
t.Fb
to carry out other func-
tions such as activating the
Aux
output, starting up the
continuous cycle, etc. (see functions of keys and ).
3.
/ Key:
In normal mode can be used to start/stop a
manual defrost (pressed for 5 s). In programming mode
is used to increase the value to be set and to select the
parameters. In programming mode can be used, to-
getherwith key to change parameters level. Pressed
together with key for 5 s allows the keyboard unlock.
4.
/ Key:
Press and release the key to display the
instrument variables (measured temperatures etc.). In
programming mode press the key for 2 s to return in nor-
mal mode. Hold pressed for 1 s, while in normal mode, it
can also be programmed via parameter
tuF
to carry out
other functions such as turn ON and OFF (stand-by) the
device, activate the
Aux
output, start up the continuous
cycle, etc. (see functions of keys and ).
5. LED SET:
During the normal operating mede, signals
that a ket is pressed. In programming mode indicates the
programming level of the parameters.
6. LED - COOL:
Indicates the output status (compres-
sor or temperature control device) when the istrument is
programmed for cooling operation: ON (
ON
), OFF (
OFF
)
or inhibited (
flashing
).
7. LED - HEAT:
Indicates the output status (compres-
sor or temperature control device) when the istrument is
programmed for heating operation: ON (
ON
), OFF (
OFF
)
or inhibited (
flashing
).
8. LED :
Indicates: Defrost in progress (
ON
) or drainage
time in progress (
flashing
).
9. LED :
hows the Fan output status: ON (
ON
), OFF
(
OFF
) or inhibited (
flashing
).
10. LED :
Shows the Alarm status (
ON
), OFF (
OFF
) and
Acknowledged or Lached (
flashing
)
11. LED Aux:
Shows the Auxiliary output status: ON (
ON
),
OFF (
OFF
) or inhibited (
flashing
).
12. LED Stand-By:
When the instrument is in Stand-by
mode is the only lit LED.
2 PROGRAMMING
2.1
Fast Set Point Programming
The normal mode to program the setpoint is done by mo-
mentarily pressing the key, the display shows
SP
(or
SP2
)
alternated to the programmed value.
To change it press the key to increase the value or 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 increases or decreases rapidly and, after
two seconds, the speed increases even more in order to
quickly reach the desired value.
When the desired value is set press the key to exit the
Set Point programming mode. The Set Point programming
mode can be abandoned by pressing the key or automati-
cally 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 function parameters when pass-
word protection is disabled, press the key and keep it
pressed for about 5 seconds, after which the display shows
the code that identifies the first programmable parameter
The desired parameter can be selected using the /
keys, then, pressing the key, the display shows the
parameter code alternated to its value that can be changed
with the and keys.
Once the desired value has been set, press the key again:
the new value is stored and the display shows only the code
of the selected parameter.
Pressing the and keys, it is possible to select another
parameter and change it as described.
To exit the programming mode, press no keys for about 30 s,
or keep the key pressed for 2 s until the controller returns
in normal mode.

Parameter Protection Using a Password
The instrument has a parameter protection function with
password that can be customized using the
t.PP
parameter.
To protect the parameters, set the desired Password Number
in parameter
tPP
.
When the protection is active, keep the key pressed for
about 5 s to access the parameters, the display shows
r.p
.
Press again the key, the display changes to
0
, now, using
the / keys, insert the programmed password number
and press the key again.
If the password is correct the instrument displays the code of
the first parameter and it will be possible to program the instru-
ment in the same way described in the previous paragraph.
The password protection can be disabled by setting
t.PP
=
oF
.
Note:
If the Password gets lost, just switch OFF and ON the
instrument power supply, push key during the initial
