1 5 1 5 1 5 delay in maximum temperature alarm (code "AH") following the disactivation of the door microswitch input (14)
1 duration of interruption in the power supply that occurs when the instrument has been running for long enough to cause the storage of
the power interruption alarm when the power supply is restored. (code "PF") (15)
2.0 2.0 2.0 differential of parameters A1and A4
1 kind of signal for power interruption alarm (code "PF"); also look at A10
0 = the alarm will not be signalled
1 = the display will show the code "PF" flashing and the buzzer will be activated
2 = the display will show the code "PF" flashing and the buzzer will be activated (this last on condition that the power interruption duration
is higher than time A10)
EVX203 EVX204/5 EVX214/5 EVAPORTOR FAN
