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 is equivalent 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 tUF = 3;
– With the key pressed for 1 s if tfb = 3;
– Using the Digital Input if parameter iFi = 7;
5.2 Normal and economic operation
This tool allows to pre-set two different Setpoints, one
Normal
-
SP
and one
Economic
-
SPE
.
Associated with each Setpoint there is the relative differential
(hysteresis):
Normal
-
rd
and
Economic
-
rEd
.
Switching between the two modes can be
automatic
or
manual
.
5.2.1
Normal/Economic operation selection
This function can be used when you need to switch two functional
temperatures (eg. Day/Night or week-day/week-end). The Normal/
Economic operation can be selected in manual mode:
– Using the key if parameter tUF = 2;
– Using the key if parameter tFb = 2;
– Using the Digital Input if parameter iFi = 6.
The Normal/Economic operation can be selected in automatic
mode:
– Elapsed the iEt time after the door has been closed
(Normal/Eco switching).
– At door opening if the SPE Setpoint is activated by iEt pa-
rameter (Eco/Normal switching).
– Elapsed the itt time after the door has been closed and from
the activation of SPE Setpoint by iEt parameter (Eco/Normal
switching).
To use this function, it is necessary to set the Digital Input as:
iFi
=
1
,
2
or
3
.
If
iEt
=
oF
the selection of Eco/Normal modes via the digital
input is disabled.
If
itt
=
oF
the time-out switching from Eco to Normal mode is
disabled.
Switching to Economic mode is indicated by the label
Eco
.
When
idS
=
Ec
the Economic mode is pointed out with a fixed
Eco
label otherwise the label
Eco
appears every 10 s alter-
nated to the display set with parameter
idS
.
The normal Set Point
SP
can be set to a value between the one
set with parameter
SLS
and the one set with parameter
SHS
while the Economic Set Point
SPE
can be set to a value between
the one set with parameter
SP
and the one set with parameter
SHS
.

Note:
In the following examples the Set point is generally
indicated as

and the differential as

however the
instrument will act according to the Set Point and the dif-
ferential selected as active.
5.3 Measure and display configuration
With the
iuP
it is possible to select the temperature engi-
neering unit and the desired measure resolution (
C0
= °C/1°;
C1
= °C/0.1°;
F0
= °F/1°;
F1
= °F/0.1°).
The instrument allows the measure calibration, which can be
used to recalibrate the instrument according to application
needs, The calibration is made by using parameters
iC1
(input
Pr1) and
iC2
(Pr2 input).
Parameter
iP2
allows to select the instrument usage of Pr2
measure as:
Au
Auxiliary
probe;
DG
Digital Input (see the Digital input functions).
If
Pr2
input is not used, set
iP2
=
oF
.
Using
iFt
parameter can be set a software filter for the measur-
ing the input values in order to decrease the sensibility to rapid
temperature changes (increasing the sampling time). Through the
idS
parameter is possible to set the variable normally displayed:
P1: Pr1
probe measurement;
P2: Pr2
probe measurement;
SP:
Active Set Point;
EC:
Probe measure if the instrument is in Normal Mode, the
label
Eco
if the instrument is in (
Eco mode
);
OFF:
If the numerical display must be switched off (
oF
).
When is displayed one of the measures
idS
=
P1
/
P2
/
Ec
the
iCU
parameter allows to set an offset that is to be applied only to the
displayed variable (all controls will always happen according to
the correct temperature value, changed only by the calibration
parameters).
Regardless of what is set at
idS
parameter, all the measure-
ment variables can be shown pressing the key.
The display alternately shows the code that identifies the vari-
able (see below) and its value. The variables are:
Pr1
Probe 1 measurement;
Pr2
Probe 2 measurement (on/oFF if Pr2 is a Digital input);
Lt
Minimum stored Pr1 temperature;
Ht
Maximum stored Pr1 temperature.
