P11 = Safety lock
0 = device unlocked. All the parameters can be
modified
1 = device locked. None of the parameters can be
modified except

tt
t can be always modified.
Select the secret code (to be remembered).
500 to 999: Selecting a secret code between
these two numbers, everything will occur as
explained above except that when the device
is “Locked” the parameters that can be
modified are the set points, the time and the
alarm thresholds.
NOTE: at a successive visualization of the P11
parameter, the instrument shows the value 2 for
any set of P11 between 2 and 999.
P12 = Out maximum rate of rise
This limit will be used if
PbPb
PbPb
Pb is different from 0 only.
Programmable from 1 to 25% of the out signal per
second.
Over 25%/s the instrument displays “
InFInF
InFInF
InF” to
indicate the exclusion of the limitation.
This limit have no effect if the selected contol
algorithm is ON/OFF type (PB=0)
P13 = Not used
P14 = Protected parameters display
This parameter is available if P11 is not 0.
This parameter enables/disables the display of the
protected parameter during "operative mode".
OFFOFF
OFFOFF
OFF = the protected parameters are not displayed
ONON
ONON
ON = the protected parameters are displayed
P15 - SMART function enabling/disabling
0 = The SMART function is disabled
1 = SMART function enabling/disabling is
NOT protected by the safety code.
2 = SMART function enabling/disabling is
protected by the safety code.
P16 - Maximum value of the proportional band
automatically settable by the SMART
function
This parameter is available if P15 is not 0. It can
assume the following values:
model LME: between P17 or P18 and 99.9%
model LDE: between P17 or P18 and 100.0%
P17 - Proportional minimum band value
automatically settable by the SMART
function ( one control out only)
This parameter is only displayed if P5 is not 5 and
P15 is not 0.
It may be programmed from 1.0% to the value of
P16.
P18 - Proportional minimum band value
automatically settable by the SMART
function (two control outs, heating/
cooling)
This parameter is only present if P5 is 5 and P15
is not 0.
This parameter may be programmed from 1.5% to
the value of P16.
