Minimum temp., low temperature in cell alarm, activates when the cell temperature is:
- below the value given by chamber set + A1 and
- lasts longer than A7
The minimum temperature reached by the cell is recorded in the Service menu, under HACCP
Found the cause of the problem

run the data memory reset (HACCP alarms)
1. Check that the "NTC probe thermostat" cabinet probe is not out of calibration

access the electronic
board
With multimeter set in Ω, check that the resistive value of the probe
matches the temperature in the surrounding environment

see tab. NTC
If the resistive value is incorrect or unstable,

replace the probe
2. Check that the parameters that manage the compressor operation,
r0,C0,C1,C2,C3, are correct, otherwise set the default values
3. If the compressor continues to work, even at room temperature reached, check if
the “K1” board relay is stuck
With board “K1” relay stuck

replace the board

set the parameters according to the field of use of the equipment
