Door-switch input (dedicated parameters u0, u1, u2):
The instrument is provided of a door-switch input which activation does not end a cycle on run but determines the action established with the
parameters "u0" and "u1" and it is indicated from the showing on the indicator DY 1 of the indication "]-[" alternated to the indication that the
indicator displayed when the door-switch input on alarm happened and (during the status "START") from the alarm buzzer activation with
intermittent beep: a door-switch input on alarm does not permit the start of an any cycle of functioning.
Locking input (dedicated parameters u3, u4):
The instrument is provided of a locking input which activation ends a cycle on run and determines the alarm buzzer activation with intermittent
beep, the showing on the indicator DY 1 of the indication "E4" alternated to the temperature read by the needle/cabinet probe when the locking
input on alarm happened and (during the status "START") the compressor, evaporator fans and defrost outputs deactivation: a locking input
on alarm does not permit the start of an any cycle of functioning.
The instrument unlocking happens when the locking input on alarm ends and (if this alarm happens during the status "START") through the
stop and the restart of the instrument.
The locking input on alarm has the priority on all alarms, except for the corrupted memory data alarm.
Manual defrost:
Push the key T 6 during the status "STOP" to activate a request of defrost: the LED L 4 flashes.
If the conditions permit it (the temperature read by the evaporator probe must be below the set established with the parameter "d2", apart from
the value established with the parameter "d4"), pressure on the key T 10 determines the activation of a defrost cycle: the indicators
DY 1 and DY 2 respectively display the indication "dEF" and, according with the selected cycle, the time established with the parameter "c1"
or the length of the quick-cooling for time or the indication "---", the LED L 4 turning on.
Push the key T 6 during a cycle/phase of cold-storing for four second at least to activate a request of a defrost cycle: if the conditions permit
it (the temperature read by the evaporator probe must be below the set established with the parameter "d2") the instrument executes a defrost
cycle; the indicators DY 1 and DY 2 respectively display the indication "dEF" and "---", the LED L 4 turning on.
A defrost cycle on run can be immediately finished keeping pushed the key T 6 for four second at least: the LED L 4 turning off.
Manual ventilation:
Push the key T 6 during the status "STOP" for four second at least to force to the status on (LED L 4 lighted) or off (LED L 4 turned off)
the evaporator fans output.
Borderline cases:
a)
if the parameter "d1" has value 2, the parameters "d7", "F0", "F1", "F2", "F3", "F4", "F5" and "u1" do not interact on evaporator fans output
status during a defrost cycle
b)
if the parameter "d1" has value 2, the door-switch input on alarm happened during a defrost cycle does not determine the alarm buzzer
activation with intermittent beep
c)
if the parameter "u1" has value 1, the door-switch input on alarm happened during a Manual ventilation does not interact on the
evaporator fans output
d)
in case of lack of power-supply happened during a defrost at the beginning of a cycle/phase of quick-cooling/freezing, when the voltage
recover the defrost cycle will reappear only if the temperature read by the evaporator probe is below the set established with the parameter
"d2" and if the parameter "d4" has value 1.
