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.
Key:
In programming mode is used for decreasing 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, a manual defrost
cycle, etc. (see functions of keys , and ).
3.
Key:
In programming mode is used to increase the
value to be set and to select the parameters. In program-
ming mode can be used, togetherwith key to change
parameters level. Pressed together with key for 5 s
allows the keyboard unlock. Hold pressed for 1 s, while in
normal mode, it can also be programmed via parameter
t.Fa
to carry out other functions such as activating the
Aux
output, a manual defrost cycle, etc. (see functions of
keys , and ).
4.
/ Key:
Press and release the key to display the instru-
ment variables (measured temperatures etc.). In pro-
gramming mode press the key for 2 s to return in normal
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, a manual defrost 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(s) status (compres-
sor or temperature control device) when the istrument is
programmed for cooling operation: ON (
ON
), OFF (
OFF
)
or inhibited (
flashing
). If both loops are programmed to
perform a cooling action, this LED signals that at least 1
output is active (OR condition). And more with both loops
programmed for cooling action but with parameter
t.Ld
=
2
,
this LED shows the
r1
controller status, while the status of
controller
r2
is shown by
Aux
LED.
7. LED - HEAT:
Indicates the output(s) status (compres-
sor or temperature control device) when the istrument is
programmed for heating operation: ON (
ON
), OFF (
OFF
)
or inhibited (
flashing
). f both loops are programmed to
perform a heating action, this LED signals that at least
1 output is active (OR condition). And more with both
loops programmed for heating action but with parameter
t.Ld
=
2
, this LED shows the
r1
controller status, while the
status of controller
r2
is shown by
Aux
LED.
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
). If several outputs are pro-
grammed for fans operation, this LED signals that at least
1 output is active (OR condition).
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
). If parameter
t.Ld
=
2
and both controllers are programmed to perform the same
action, this LED can indicate the status of controller
r2
.
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
waypressing t key, however, using the
t.Ed
parameter, it
is possible to establish whether and which Set Points can be
set with the fast procedure of the key.
t.Ed
parameter can take a value between
0
and
3
:
oF
No Set Point can be set with the key fast procedure
(the key pressed and released has no effect);
1
Only SP1 can be set;
2
Only SP2 can be set;
3
Both SP1 and SP2 can be set.

NORMAL MODE
Press
and
release
For example, if parameter
t.Ed
=
1
or
3
, the procedure is:
Press and release the key, the display will show the label
SP1
alternated to its 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.
If only
SP1
(
t.Ed
=
1
) can be modified, once its desired value
has been set, pressing the key exits the fast setting mode.
If, instead, also
SP2
(
t.Ed
=
3
) can be set, pressing the
key again, the display will show
SP2
alternated to its value.
To change it press the / keys as has been done for SP1.
When all the desired values are set, press the key or wait
for about 15 s pressing no keys to exit the Fast Set Point
Programming mode, after that time the display returns to the
normal operating mode.
A different way to access the individual fast Set Points
chenge can be achieved by appropriately programming the
respective parameters
t.FA
and
t.Fb
. When these param-
eters are correctly programmed, each Set Point can be re-
called for changes pressing and releasing the the by press-
ing and quickly releasing the and keys.
In this case, after changing a Set Point with this modality, the
procedure is always exited pressing the key or, automati-
cally, pressing no keys for about 15 s, after which the display
returns to the normal operating mode.
