FUNCTIONING:
Pressure on key T 10 determines the start (status "ON", LED L 8 lighted) or the stop (status "STAND-BY", LED L 8 turned off) of the instrument:
at any new restart the last programming will reappear; in case of lack of power-supply, when the voltage recover the last programming will reappear
but an eventual count of a time will start from the beginning.
Pressure on key T 7 during the status "STOP" selects the modality of quick-cooling/freezing of food temperature (for temperature, with LED
L 5 lighted and LED L 6 turned off or for time, with LED L 5 turned off and LED L 6 lighted).
During the status "STOP" it is possible to select the desired cycle of functioning.
Cycle number 1a: Quick-cooling for temperature:
Push the key T 1 to select this cycle and the key T 10 to start it: the LED L 2 turning on.
If the parameter "d4" is set to 1 and if the conditions permit it (the temperature read by the evaporator probe must be below the set established
with the parameter "d2"), the instrument automatically executes a defrost cycle to permit a best performance of refrigerating system: the indicators
DY 1 and DY 2 respectively display the indications "dEF" and the time established with the parameter "c1", the LED L 7 turning on (during
this cycle the defrost will never be activated again).
In order to assure a correct execution of a cycle of quick-cooling it is necessary that the needle probe is properly positioned inside the product:
so, the instrument (after pressure on key T 10), executes a test to verify the proper insertion of the needle probe (see the paragraph Needle
probe properly positioned verify).
If the test has an happy success and if the conditions permit it (the eventual defrost cycle must be finished and the temperature read by the
needle probe must be lower to the set established with the parameter "c8"), the instrument starts the cycle: the indicators DY 1 and DY 2
respectively display the temperature read by the needle probe and the decrease of the time established with the parameter "c1", the LED L 7
flashes to indicate that a count of a time is on run, the outputs concerning get activated.
The kind of temperature regulation is ON-OFF: the temperature that regulates the compressor activity is the temperature read by the cabinet
probe, the set can be established with the parameter "cb", the hysteresis can be established with the parameter "c0"; the evaporator fans output
