time has elapsed since the door is no longer opened, the
controller switches to
ECO
mode. At the first door re-open-
ing the controller returns to
Normal
mode.
To use this function, it is necessary to set the Digital Input as:
o
F
=
1
,
2
or
3
(Open Door input)(
o
F
=
2
or
3
for P34).
If
Et
=
oF
the selection between
Eco
/
Normal
modes via a
digital input is disabled.
If
tt
=
oF
the time-out switching from
Eco
to
Normal
mode
is disabled.

Switching to Economic mode is pointed out on the P03 by
the switching ON of the LED
or, on the P34, by the
label
Eco
shown on the display alternated, every 10 s, to the
normal display.
To the selection of the Eco mode operation is often associ-
ated the switching OFF of the output configured as
L1
(shop
window light).
5.2.2
Turbo/Normal/Economic operation selection
Turbo mode
can be
manually activated
when the tempera-
ture of the goods must be lowered after the refrigerator loading
phase. Or, it
can be used
to
automatically recover
the
tem-
perature of the products
at the
end
of the
economy mode
.
Turbo
mode can be
manually activated
by:
–
Holding pressed the /
trb
key for 5 s;
–
A digital input if parameter if
o
F
= 8.
The
Turbo
mode can also be
atomatically activated
:
–
At the end of the
ECO
phase mode (only if:
HC
=
C3
);
–
At each instrument Power ON ( (only if:
HC
=
C3
and
Pr1
>
SE
+
Ed
).
The exit from the
Turbo
mode automatically occurs after the
tC
time has elapsed or manually via a programmed command
(key or digital input); the instrument returns to
normal
mode.
The active
Turbo
mode is pointed out on the display with the
label
tr
alternated, every 10 s, with the normal display.
By setting
HC
=
C3
, the operating cycle is as follows:
At Power ON, the instrument starts in the same control mode
it was in when it has been switched OFF (
Normal
or
ECO
)
unless the power ON temperature is
Pr1
>
SE
+
Ed
. In this
case, a
Turbo
cycle is automatically started.
After the
tC
time has elapsed, the instrument automatically
switches to
Normal
mode.
If the door is opened frequently, the instrument remains in
Normal
mode, but, if it is not open for the time set at
Et
parameter, it automatically switches to
ECO
mode.
The instrument remains in
ECO
mode until the door is re-
opened or, if set, until the
tt
timeout.
Exiting from the
ECO
mode, the instrument performs a
Turbo
cycle to allow goods temperature recovery after which
it returns to normal operation mode and so on.

5.3
Measure and display configuration
All the parameters for configuring the inputs are contained in
the
-In
group.
With the
uP
parameter it is possible to select the tempera-
ture engineering 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
C1
(
Pr1
input),
C2
(
Pr2
input) and
C3
(
Pr3
input).
Parameters
P2
and
P3
allow to select the instrument usage
of
Pr2
and
Pr3
measure as:
EP
Evaporator Probe:
The probe performs the functions
described below in order to control defrosters and
evaporator fans;
Au
Auxiliary Probe:
Can be used as a probe for display
only but it is also possible to associate it with tempera-
ture alarms (possible uses: product probe, anti-freeze
probe etc.);
cd
Condenser Probe:
Can be used as a probe for display
only, but it is also possible to associate it with tem-
perature alarms to indicate condenser malfunctioning
alarms (e.g. dirt/clogged condenser);
dG
Digital Input:
see Digital Input Functions.
If a probe input is not used, set
iP
o
=
oF
(
o
is the probe
number).
It is not possible set 2 probe inputs for the same function. If
two inputs are set for the same function, this is done by the
probe with the lower number input.
With
ft
parameter can be applied a software filter to the
measurement input values in order to decrease the instru-
ment sensibility to rapid temperature changes (increasing
the sampling time).
In addition to this filter, there are 2 other similar filters that are
used only for probe
Pr1
display for measurement increasing
(parameter
Du
) and the decreasing (parameter
dd
) to avoid
displaying rapid temperature variations.
The filter locks the maximum decrement displayed at 0.1° eve-
ry
dd
seconds and the maximum increment displayed every
du
seconds. The filters are reset at Power ON.
In order to display the so filtered
Pr1
masure it is necessary to
set parameter
dS
=
F1
differently program
dS
=
P1
.
DS
parameter can be used to establish what is normally
shown on the display:
P1
Probe Pr1 measurement;
P2
Probe Pr2 measurement;
P3
Probe Pr3 measurement;
