FRONT PANEL DESCRIPTION
1 - Key P
: This is used to access the programming parameters
and to confirm selection.
2 - Key DOWN
: This is used to decrease the values to be set and
to select the parameters. If the key is held down, the user returns to
the previous programming level until he exits the programming
mode.
3 - Key UP
: This is used to increase the values to be set and to
select the parameters. If the key is held down, the user returns to
the previous programming level until he exits the programming
mode. Outside the programming mode it permits visualisation of
the output control power.
4 - Key U
: This is a key with a function programmable by par.
“USrb”. It can be set to : Activate Auto-tuning and Self-tuning
functions, swap the instrument to manual control, silence the alarm,
change the active Set Point, deactivate control.
5 - Led Heat
: indicates the HEAT mode
6 - Led Cool
: indicates the COOL mode
7 - Led AL1
: indicates the state of output AL1
8 - Led AL2
: indicates the state of output AL2
9 - Led AT/ST
: indicates that the Self-tuning function is activated
(light on) or that Auto-tuning (flashing ) is in progress.
10 - Led SET
: when flashing, it indicates access to the
programming mode.
11 - Led – Shift index:
indicates that the process value is lower
than the one programmed on par. “AdE”.
12 - Led = Shift index:
indicates that the process value is within
the range [SP+AdE ... SP-AdE]
13 - Led + Shift index:
indicates that the process value is higher
than the one set on par. “AdE”.
2 - PROGRAMMING
2.1 - FAST PROGRAMMING OF THE SET POINT
This procedure permits rapid programming of the active Set Point
and possibly the alarm thresholds (see par 2.3)
Push key “P”, then release it and the display will visualise
“SP n”
(where n is the number of the Set Point active at that moment)
alternatively to the programmed value.
To modify the value, press “UP” key to increase it or the “DOWN”
key to decrease it.
These keys change the value one digit at a time but if they are
pressed for more than one second, the value increases or
decreases rapidly and, after two seconds in the same condition, the
changing speed increases in order to allow the desired value to be
reached rapidly.
Once the desired value has been reached, by pushing key P it is
possible to exit by the fast programming mode or it is possible to
visualise the alarm thresholds (see par. 2.3).
To exit the fast Set programming it is necessary to push key P,
after the visualisation of the last Set Point, or alternatively, if no key
is pressed for approx. 15 seconds, the display will return to normal
functioning automatically.
2.2 - SELECTION OF THE CONTROL STATE AND PARAMETER
PROGRAMMING
By pushing key "P" and holding it down for approx. 2 sec. it is
possible to enter into the main selection menu.
Using the "UP" or DOWN” keys, it is then possible to roll over the
selections:
"OPEr"
to enter into the operating parameters menu
"ConF"
to enter into the configuration parameters menu
"OFF"
to swap the regulator into the OFF state
"rEG"
to swap the regulator into the automatic control
state
"tunE"
to activate the Auto-tuning or Self-tuning function
"OPLO"
to swap the regulator to the manual control state
and therefore to program the % control value using
the “UP” and “DOWN” keys
Once the desired item has been selected, push key “P” to confirm.
Selecting "OPEr" and "ConF" gives the possibility of accessing
other menus containing additional parameters and more precisely :
"OPEr" -
Operating parameters Menu: this normally contains the
Set Point parameters but it can contain all the desired parameters
(see par. 2.3).
"ConF" -
Configuration parameters Menu: this contains all the
operating parameters and the functioning configuration parameters
(alarm configuration, control, input, etc.)

To enter the menu
“ConF”
select the option “ConF”, press the key
“P” and the display will show “0”.
At this request, enter, using keys “UP” and “DOWN”, the number
reported on the last page of this manual and push key “P”.
If an incorrect password is entered, the instrument exit from
programming mode.
If the password is correct, the display will visualise the code
identifying the first group of parameters (“
]
SP
“) and with keys “UP”
and “DOWN” it will be possible to select the desired group of
parameters.
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 “P” key.
Again using the “UP” and “DOWN” keys, it is possible to select the
desired parameter and, if the key “P” is pressed, the display will
