DESCRIPTION
PAR.
ALARMS (folder with "AL" label)
Alarm type. Parameter "HAL" and "LAL" modes, as absolute tempera-
Att
ture values or as differential compared to the Set point. 0 = absolute
value; 1 = relative value.
Alarm Fan differential. Alarm differential. Power-on Alarm Override.
AFd
PAO (!) Alarm exclusion time after instrument start-up following a power fail-
(2) ure.
SAO Set point Alarm Override. Alarm exclusion time after reaching set
point. 0 = disabled. If >0, an alarm will be generated if the set point
is not reached after the time (in hours) set by this parameter.
temperature Alarm Override. Temperature alarm signal delay time.
tAO (2)
Alarm Output Polarity. Polarity of alarm output.
AOP
0 = alarm active and output disabled; 1 = alarm active and output
enabled.
COMMUNICATION (folder with "Add" label)
dEvice Address. dEA = device address in family (valid values from 0 to
dEA (!)
14)
FAmily Address. FAA = device family (valid values from 0 to 14)
FAA (!)
The pair of values FAA and dEA represents the device network
address and is indicated as "FF.DD" (where FF=FAA and DD=dEA).
DISPLAY (folder with "diS" label)
Keyboard locked (set point and buttons). However, you can still
LOC
access the parameter programming menu and modify parameters
including the status of this parameter to allow keyboard unlocking.
y = yes; n = no.
Password 1. When enabled (value is not 0) it represents the access
PA1
button to level 1 parameters.
Password 2. When enabled (value is not 0) it represents the access
PA2****
button to level 2 parameters.
number display type. Display with decimal point.
ndt
y = yes; n = no.
Calibration 1. Positive or negative temperature value that is added to
CA1
the value read by control probe (probe 1) before being displayed or
used for control.
Calibration 1. Positive or negative temperature value that is added to
CA2
the value read by control probe (probe 2) before being displayed or
used for control.
CAI CAlibration Intervention. Intervention of offset on display, thermostat
control or both.
0 = only modifies the temperature displayed;
1 = adds to the temperature used by controllers, not the tempera-
ture displayed that remains unchanged;
2 = adds to temperature displayed that is also used by controllers.
Low display Label. Minimum value the instrument is able to display.
LdL
High display Label. Maximum value the instrument is able to display.
HdL
Low Limit Setpoint. Minimum value the instrument is able to display.
LLS
High Limit Setpoint. Maximum value the instrument is able to display.
HLS
Select °C or °F to display temperature read by probe.
dro
N. B.: switching from °C to °F DOES NOT modify set points, dif-
ferentials, etc. (for example set point=10°C becomes 10°F).
Selection of the value type to be displayed.
ddd
0 = Set point;
1 = probe 1 (Pb1);
2 = probe 2 (Pb2);
CONFIGURATION (folder with "CnF" label)
For selection of probe type, PTC or NTC.
H00(1)(!)
Output link. 0 = independent; 1 = dependent; 2 = Neutral Zone (or
H01
window)
Button activation time if buttons are configured for a second func-
H02
tion.
For the ESC, Up and DOWN buttons configured for a second func-
tion (defrost, aux, etc) the time for rapid enabling is set. Aux is an
exception and has a set time of 1 second
Adjustment type SEE DIFFERENTIAL AND SETPOINT OFFSET
H03
ADJUSTMENT
0 = standard adjustment;
1 = adjustment according to difference between Pb1-Pb2 and set point;
2 = set point adjustment calculated as offset from probe Pb2 Setting
H04 value on basis of which temperature alarms will be signalled SEE
ALARM DIAGRAM HIGH AND LOW TEMP.:
0 = Pb1-Pb2;
1 = Pb1;
2 = Pb2;
3 = Pb1 e Pb2.
Window filter. -2=very fast; -1=fast; 0=normal; 1=slow; 2=very slow
H05
button/aux input/door switch light active when instrument is off (but
H06
powered)
Stand-by operating mode.. 0= only display switched off; 1= display
H08
on and controllers locked; 2= display off and controllers locked;
Output delay from power-on. Attention! If = 0 is not active; if ≠ 0
H10
the output will not be activated before this time has expired
***NOTE: At level 1 the folders will only display all the level 1 parameters. At level 2 the folders will only
display all the level 2 parameters.
