The display will now show the code identifying the first group of
parameters (
]
SP
) and, by pressing the
and
keys, it will
be possible to select the group of parameters to be modified.
Once the desired group of parameters has been selected, the
code identifying the first parameter of the selected group will
be visualised by pushing the
key.
Again using the
and
keys, it is possible to select the
desired parameter and, if
is pressed, the display will alter-
natively show the parameter code and its programming value,
which can be modified by using the
/
keys.
As the desired value has been programmed, press
once
again: the new value will be stored and the display will show
only the code of the selected parameter.
By using the
/
keys, it is then possible to select a new
parameter (if present) and modify it as described above.
To select another group of parameters, keep the
or
key
pressed for about 2 s, afterwards the display shows again the
code of the group of parameters.
Release the key and, using the
or
keys, select a new
group (if present).
To exit the programming mode, press no keys for about 20
seconds, or keep the
or
pressed until the controller
exits the programming mode.
To access the
ConF
menu, the controller can ask for a person-
alized Password previously set through the
PASS
parameter.
If the protection is requested, set the desired password number
in the
PASS
parameter and exit the programming parameters.
When the protection is active, to access the
Conf
menu pa-
rameters, it is necessary to insert the programmed password
number; to do that, use the
and
keys to make the num-
bers scroll on the display until the previously programmed
PASS
number is shown on the screen, at this point press the
key.
If a wrong
PASS
number is entered, the instrument returns to
the previous control state.
If the password is correct, the display shows the code of first
group of parameters (
]
SP
) and, using the
/
keys, is pos-
sible to select the desired group of parameters.
The modes to program and exit the
ConF
menu parameters
are the same described for those in the
oPEr
menu.
The protection Password is deactivated by setting:

Note:
If the password is lost, turn OFF the instrument, press
and turn the instrument back ON keeping the key
held down for about 5 s. In this way access is made to
all parameters of the
ConF
menu and it will therefore
be possible to check and modify the
PASS
parameter.
2.3 Parameters programming levels
The menu
oPEr
normally contains the parameters used
to program the Set Point; however it is possible to make all
desired parameters appear or disappear on this level, by fol-
lowing this procedure:
Enter the menu
ConF
and select the parameter to be made
programmable or not programmable in the menu
oPEr
.
Once the parameter has been selected, if the LED SET is
OFF, this means that the parameter is programmable only in
the menu
ConF
, if instead the SET LED is ON, this means
that the parameter is also programmable in the menu
oPEr
.
To modify the visibility of the parameter, press key
: the LED
SET changes its state indicating the parameter accessibility
level (
ON
=
oPEr
+
ConF
menus;
OFF
=
ConF
menu only).
The active Set Point and the alarm thresholds will only be
visible on the Set Point fast programming level (paragraph
2.1) if the relative parameters are programmed to be visible
(i.e. if they are present in the
oPEr
menu).
The possible changes to these Set Points, with the proce-
dure described in paragraph 2.1, is instead subordinate to
what is programmed in parameter
Edit
(in the group
]
PAn
).
This parameter can be programmed as:
SE
The active Set Point can be modified while the alarm
thresholds cannot be modified;
AE
The active Set Point cannot be modified while the
alarm thresholds can be modified;
SAE
Both the active Set Point and the alarm thresholds can
be modified;
SAnE
Both the active Set Point and the alarm thresholds
cannot be modified.
2.4 Control Satus
The controller can act in 3 different ways:
rEg
Automatic control;
oFF
Control OFF;
oplo
Manual control.
The instrument is able to pass from one state to the other:
–
Through the instrument keyboard to selecting the desired
status from the main selection menu;
–
By using the key
on the keyboard; suitably program-
ming parameter
USrb
(
USrb
=
tunE
;
USrb
=
oPLo
;
USrb
=
OFF
) it is possible to pass from
rEG
state to the
state programmed for the parameter and vice versa;
–
By using the digital input 1 suitably programming param-
eter
diF
(
diF
=
OFF
) it is possible to pass from
rEG
state
to the state
OFF
and vice versa.
–
Automatically (the instrument swaps into
rEG
state at the
end of the auto-tuning execution).
When switched ON, the instrument automatically resumes
the status it was in when it was switched OFF.
rEG
Automatic control:
Automatic control is the normal func-
tioning status of the controller. During automatic control,
pressing key
, is possible to show, on the display, the
control power. The range of the power value goes from:
H100
(100% of output power for
reverse
heating action);
C100
(100% of output power for
direct
cooling action).
oFF
Control OFF:
The instrument can be swapped into
the
OFF
status, i.e. the control and the relative outputs
are deactivated. The alarm outputs are instead work-
ing normally.
oPLo
Bumpless manual control:
By means of this option
it is possible to manually program the power percent-
age given as output by the controller by deactivating
automatic control.
When the instrument is swapped to manual control, the
power percentage is the same as the last one supplied
and can be modified using the
/
keys. In the case
of
ON/OFF
type setting,
0%
corresponds to the output
