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 to confirm values. In programming mode it can
be used together with the key to change the program-
ming 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 to decrease
the parameters value and to select the setting parameter.
Hold pressed for 1 s while in normal mode it can also be
used, when programmed via parameter
t.Fb
, to carry out
other functions such as activating the
Aux
output etc.
(see functions of keys and ).
3.
/Tm Key:
Hold pressed for 1 s while in normal mode
can be used to start/stop the twin timer when it is pro-
grammed in
ofo
=
2
mode. In programming mode is
used to increase the parameters value and to select the
setting parameter. In programming mode can be used,
togetherwith key to change parameters programming
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 used, when programmed via parameter
tuf
,
to carry out other functions such as activating the
Aux
output etc. (see functions of keys and ).
5. LED SET:
During the normal operating mode, signals
that a key 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 the status of the humidity control output
when the operating action is that of dehumidification:
ON (
ON
), OFF (
Off
) or inhibited (
flashing
).
9. LED :
Indicates the status of the humidity control output
when the operating action is that of humidification:
ON (
ON
), OFF (
Off
) or inhibited (
flashing
).
10. LED :
Shows the Alarm status (
ON
), OFF (
Off
) and
Acknowledged or Lached (
flashing
)
11. LED Au:
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.
13. LED Tm (Time)
: When flashes points out that the twin
timer which operates on the Auxiliay output is enabled.
2 PROGRAMMING
2.1
fast Set Point Programming
The normal mode to program the setpoint is done by momen-
tarily pressing the key, the display shows
SPt
(or
SPh
)
alternated to the programmed value.
To change the SP, 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.
However, through parameter
t.Ed
is possible to establish if
and which Set Points can be set with th ekey fast proce-
dure.
t.Ed
parameter can be set to a value between
of
and
3
:
of
No
Set Points can be set with the key fast procedure
(pressing and releasing the key has no effect);
1
Only
SPt
can be set (Temperature Set Point);
2
Only
SPh
can be set (Humidity Set Point);
3
Both
SPt
and
SPh
can be set.
For example, if
t.Ed
=
1
o
3
, the procedure is:
–
Press and release the key, the display shows the label
SPt
alternated to the
SPt
value. To change it, press the
key to increase
SPt
value or to decrease it.
–
If
t.Ed
=
1
(only the temperature Set Point can be changed),
once set the
SPt
value, pressing the key, the instru-
ment returns to the
Standard Display
.
–
When instead
t.Ed
=
3
(both
SPt
and
SPh
can be set),
pressing the key, the instrument shows
SPh
alternated
to the
SPh
value. To change it, use the / keys as for
the
SPt
Set Point.
When all the desired values are set, press the key to exit
the Set Point programming mode. The Set Point program-
ming mode can be abandoned by pressing the 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 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 selected
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.
