from line voltage wiring. If the iprobes cables are shielded, the
shield must to be connected to ground at only one side.

We recommend that a check should be made that the
parameters are those desired and that the application
functions correctly
before connecting the outputs to
the actuators
so as to avoid malfunctioning that may
cause irregularities in the plant that could cause dam-
age to people, things or animals.

5. FUNCTIONS
5.1
ON/Stand-by function
Once powered the instrument can assume 2 different condi-
tions:
ON
: Means that the controller uses the control functions.
STAND-BY:
Means that the controller uses no control function and
the display is turned off except for the Stand-by LED.
The transition between Standby and ON condition is equiva-
lent to power ON the instrument providing the electrical power.
In case of power failure, the system always sets itself in the
condition it was in before the black-out.
The ON/Stand-by function can be selected:
–
With the key / pressed for 1 s if
UF
=
2
;
–
Using a Digital Input if parameter
o
F
=
7
(where
o
is the
number of the digital input:
o
= 1 ÷ 4 for P03 or
o
= 2 ÷ 4 for P34).
5.2
Normal, Economic and Turbo operation
The controller allows to pre-set 5 different control Set Points:
S1
,
S2
,
S3
are
Normal
Set Points,
SE
is an
Economic
Set Point;
SH
is a
Turbo
Set Point.
Associated with each Setpoint there is the relative differential
(hysteresis):
Normal
-
d
,
Economic
-
Ed
and
Turbo
-
Hd
.
As explained at paragraph “
2.1 Fast programming of normal Set
Point
”, the operative
Normal
Set Point is
only 1
, in particular:
S1
if
Ed
=
1
or selectable between:
S1
,
S2
,
S3
pre-set values if
Ed
=
2
.
Note:
In the examples that follow, the Set Point is generi-
cally indicated as
S1
, but the instrument controls the
process using the active Set Point.
5.2.1
Normal/Economic operation selection
This function can be used if it is necessary to switch two func-
tional temperatures (eg. Day/Night or week-day/week-end). The
Normal/Economic operation can be selected in manual mode:
–
Using the / key if parameter
UF
=
2
;
–
Using a Digital Input if parameter
o
F
=
6
(
o
= DI #).
The Normal/Economic operation can be selected in automatic
mode:
–
Elapsed the
Et
time after the door has been closed
(Normal/Eco switching).
–
At door opening if the Eco function is active (Eco/Normal
switching).
–
Elapsed the
tt
time after the door has been closed and
from the activation of Eco function (Eco/Normal switching).
