5.3.8 Mode 8: Reverse with set point & di erential,
changeover from DI1 c0=8
The controller always operates in “reverse” mode, based on St1 when
digital input 1 is open and based on St2 when it is closed.

For models W & Z the activations of the outputs are equally distributed
across the di erential (P1/P2).
Parameter c29 is not active in mode 8.
5.3.9 Mode 9: Direct/reverse with two set points c0=9
In this mode, available only on the models with 2 or 4 outputs, half of the
outputs are active in “direct” mode and half in “reverse”. The unique aspect
is that there are no restrictions in the setting of the set point for the two
actions, therefore it is like having two independent controllers that work
with the same probe.

5.4 Validity of control parameters
(parameters St1,St2,P1,P2,P3)
The parameters that de ne the operating mode have the validity de ned
in the table below:
Parameter Validity Note
St1 All modes
St2 c0 = 6,7,8,9 or any value
of c0 if c33 = 1(special
operation). If c19=2,
3 or 4, St2 is used in
compensation.
If c19=2, 3.4, 7, 11,
St2 is used for control. If
c19=7 St2 is the set point
for circuit 2..
In special operation(c33=1),
St2 is set on the keypad in all
modes, but is only active for
outputs with dependence
equal to 2.
P1 All modes
P2 c0=3,4,5,6,7,8,9
Active also in other modes
if c33=1 (special operation)
or c19=4.
note that in modes 3, 4 and
5, P2 is the di erential of the
“direct” action and refers to St1.

Parameter c33 o ers the possibility to create custom operating logic,
called special operation. The logic created may be a simple adjustment
or a complete overhaul of one of the nine modes. In any case, note that:
• Modes 1, 2, 9: do not consider the dead zone P3 nor the changeover in
logic from digital input
• Modes 3, 4, 5: enable the dead zone di erential P3. No changeover in
logic from digital input.
• Mode 6: does not consider the di erential P3. The changeover of
digital input 1 means the outputs consider set point 2 rather than
set point 1. The direct/reverse logic will be inverted. For outputs with
“dependence”=2, only the changeover in logic is active, that is, the
closing of the digital contact maintains “dependence”=2 (St2) but
inverts the logic, exchanging the signs for “activation” and “di erential/
logic” (see the explanation below).
• Modes 7, 8: do not consider the dead zone P3. For outputs with
“dependence”=1, the digital input only shifts the reference from St1/P1
to St2/P2, maintaining the control logic (“activation” “di erential/logic”
do not change sign). The digital input does not have any in uence on
the other control outputs, that is, with “dependence”=2 and alarms.
For the explanation of the “dependence”, “activation” and “di erential/
logic” parameters, see the following paragraphs.
Before selecting c33=1: for starting modes other than c0=2 (default),
this must be set before enabling special operation (c33=1): the
change to c0 must be saved by pressing
.
When c33=1, changing c0 no longer a ects the special parameters.
That is, c0 can be set however the special parameters (from c34 to
d49) and the typical functions remain frozen in the previous mode with
c33=1: while the parameters can be set individually, the typical functions
cannot be activated. In conclusion, only after having set and saved the
starting mode can the parameters be edited again and c33 set to 1.
f the mode needs to be changed after c33 has been set to 1,  rst
return c33=0, press
to con rm, set the required mode and save
the change
, then return to special operation with c33=1. Setting c33
from 1 to 0, the controller cancels all changes to the “special parameters”,
which return to the values dictated by c0..
