duration of a power cut that occurs when the instrument is on such to cause memorisation of the power supply cut-off alarm, when the power supply is restored (“
PF
”
code) (15)
differential of parameters A1 and A4
type of power supply cut-off alarm signal (“
PF
” code); see also A10
0 = the alarm will not be signalled
1 = the display will show the flashing “
PF
” code and the buzzer will be activated
2 = the display will show the flashing “
PF
” code and the buzzer will be activated (the latter on the condition that the duration of the power supply cut-off is longer than
time A10)
EVAPORATOR FAN
evaporator fan activity during normal functioning
0 = off
1 = on; se also F13, F14 and i10
2 = parallel to the compressor; se also F9, F13, F14 and i10
3 = depending on F1 (16)
4 = off if the compressor is off, depending on F1 if the compressor is on; see also F9 (16)
5 = depending on F6; see also F9
evaporator temperature over which the evaporator fan is switched off (sonly if F0 = 3 or 4); see also F8
activity of the evaporator fan during defrosting and dripping
0 = off
1 = on (it is recommended to set parameter d7 at 0)
2 = depending on F0
maximum duration of the evaporator fan standstill; see also F7 (during evaporator fan standstill, the compressor may be on, the defrosting output will remain deactivated
and the evaporator fan will remain off)
duration of evaporator fan switch-off during functioning due to low relative humidity percentage when the compressor is off; see also F5 (only if F0 = 5)
duration of evaporator fan switch-on during functioning due to low relative humidity percentage when the compressor is off; see also F4 (only if F0 = 5)
