LIST OF LEVEL 1 VARIABLES (User level)
VARIABLE
MEANING
VALUES
DEFAULT
r0
Temperature differential
referred to main SETPOINT
(both set points where double)
0,2 ÷ 10,0 °C
2,0°C
d0
Defrost interval
(hours).
In the case of the double evaporator defrost start is simultaneous.
0 ÷ 24 hours
0 = disabled
4 hours
d21
End-of-defrost set point, evaporator 1
.
Defrost is not executed if the temperature read by the defrost
sensor is greater than value
d21.
(If the sensor is faulty defrosting
is time-based)
-35,0 ÷ 45,0 °C
15,0°C
d22
End-of-defrost set point, evaporator 2
.
Defrost is not executed if the temperature read by the defrost
sensor is greater than value
d22.
(If the sensor is faulty defrosting
is time-based)
-35,0 ÷ 45,0 °C
15,0°C
d31
Maximum defrost duration, evaporator 1
(minutes)
1 ÷ 120 min
25 min
d32
Maximum defrost duration, evaporator 2
(minutes)
1 ÷ 120 min
25 min
d7
Drip duration
(minutes)
At the end of defrosting the compressor and the fans remain at
standstill for time setting
d7
: the defrost LED on the front of the
panel flashes.
0 ÷ 120 min
0 min
F5
Fan pause
after defrost (minutes)
Allows fans to be kept at standstill for a time
F5
after dripping. This
time is counted from the end of dripping. If dripping is not set the
fan pause is executed directly after the end of defrosting. During
the pause the fan icon flashes.
0 ÷ 10 min
0 min
dEL
Second system start delay
(valid if nrC=2 e Set=1)
0-60 min
30 min
A1
Minimum temperature alarm
Allows user to define a minimum cold room storage temperature.
Below the value
A1
(after Ald delay) a warning is given: the alarm
LED and the alarm code EL flash and the fault is also highlighted
by an internal buzzer.
-45 ÷ (A2-1)°C
-45°C
A2
Maximum temperature alarm
Allows user to define a maximum cold room storage temperature.
Above the value
A2
(after Ald delay) a warning is given: the alarm
LED and the alarm code EH flash and the fault is also highlighted
by an internal buzzer.
(A1+1) ÷ 99°C
+45°C
dF1
Real-time defrost enable, evaporator 1
With
dF1
=1 it is possible to set up to 6 defrosts in real time in a
day by using the parameters d41…d46
(not considered if d0 differs from 0).
0 disabled
1 enabled
0
dF2
Real-time defrost enable, evaporator 2
With
dF2
=1 it is possible to set up to 6 defrosts in real time in a
day by using the parameters d51…d56
(not considered if d0 differs from 0).
