cording what established with the parameters of the family i.
WORKING SETPOINT
WORKING SETPOINT SETTING (WORKING TEMPERATURE)
To modify the working setpoint value keep pushed the key T3 (the instrument displays the
actual value) and at the same time push and release over and over the key T1 or T2 as long as
the instrument displays the desired value (keeping pushed the key T1 or T2 the value gets
decreased or increased more quickly): after the modification release the key T3 last; during the
pressure of the key T3 the LED L1 flashes quickly to indicate that a working setpoint setting
procedure is running (to the release of the key T3 the instrument automatically turns out from
the working setpoint setting procedure).
ADDITIONAL INFORMATIONS
-
for the whole period of a corrupted memory data alarm the access to the working
setpoint setting procedure is refused
- the working setpoint is programmable within the limits established with the param-
eters r 1 and r 2
- if the parameter r 5 has value 1 the working setpoint can not be modified as long as
the parameter r 5 gets set to 0
- the working setpoint value gets stored in a non volatile memory even if a lack of
power supply happens.

CONFIGURATION PARAMETERS
CONFIGURATION PARAMETERS SETTING
Configuration parameters are arranged on two levels, to protect the most tricky settings against
undesirable violations and they are arranged in families that can be recognized through the
initial letter of the label.
To gain access to the first level keep pushed at the same time for four seconds at least the keys
T1 and T2 (passed four seconds the instrument displays the label PA).
To select a parameter of the first level push and release over and over the key T1 or T2 as long
as the instrument displays the label of the desired parameter.
To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets de-
creased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).
To gain access to the second level enter inside the first level and select the label PA.
Keep pushed the key T3 (the instrument displays the actual value) and at the same time push
and release over and over the key T1 or T2 as long as the instrument displays -19 (keeping
pushed the key T1 or T2 the value gets decreased or increased more quickly): after the modi-
fication release the key T3 last (to the release of the key T3 the instrument displays the label PA
again); keep pushed at the same time for four seconds at least the keys T1 and T2 (passed four
seconds the instrument displays the first parameter of the second level).
To select a parameter of the second level push and release over and over the key T1 or T2 as
long as the instrument displays the label of the desired parameter.
To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets de-
creased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).
To turn out from the configuration parameters setting procedure keep pushed at the same time
for four seconds at least the keys T1 and T2 or do not operate with the keys for fifty seconds
at least (time-out exit).
ADDITIONAL INFORMATIONS
-
for the whole period of a corrupted memory data alarm the access to the configura-
tion parameters setting procedure is refused
- the modification of the parameter /Ab value has not immediate effect; to obtain this
effect, after the modification turn OFF and turn ON again the instrument
- the modification of a parameter value which unit of measure is the hour or the
minute or the second has not immediate effect; to obtain this effect it must not be
executed during the course of the value
- the configuration parameters values get stored in a non volatile memory even if a
lack of power supply happens.

nal).

TIONS.

It is significant exclusively if the parameter / 8 has value 1, it establishes the resolution with
which the temperature gets displayed, as indicated:

1 = the unit of measure is the Celsius degree.
/Ab 0 1 --- 1 evaporator probe enabling
It establishes if to enable the evaporator probe, as indicated:
0 = the evaporator probe is disabled
1 = the evaporator probe is enabled.

It is significant exclusively if the parameter d E has values different to 3.
If the parameter d E has value 0 it establishes the time interval that pass from the moment of the

cycle to the moment in which the instrument automatically presents the following request of a
defrost cycle.
If the parameter d E has value 1 it establishes for which time interval the compressor output
must be remained activated from the moment of the instrument start or from the moment in
which the instrument activates a defrost cycle in order that the instrument can automatically
activate the following defrost cycle.

the evaporator probe must be remained below the setpoint established with the parameter d F
from the moment of the instrument start or from the moment of a defrost cycle end in order
