Defrost config.
Timer + Auto Tuning
Sets 3 defrost types:
Traditional, defrosting at fixed intervals,
Timer Tuning, defrosting at dynamic intervals,
Timer Tuning + Auto Tuning, defrosting at dynamic intervals, also analysing evaporation
pressure values.
21.01
Defrost parameters:
Start 03.0 bar
Stop 14.0 bar
Defines the pressure setpoints for start and stop defrost. 21.02
21.03
Defrost parameters:
Delay 01800 s
Max. time 00300 s
Drip time 120 s
Sets defrost time parameters.
Delay: cumulative time measured before the defrost procedure starts.
Max. time: maximum duration of defrost procedure.
Drip time: duration of coil dripping

Timer tuning defrost
Ref. time 120 s
Ref. T. -10°C 180 s
Ref. T. +10°C 060 s
Sets certain timer tuning defrost parameters.
Nominal defrost reference time (display only).
Reference time at -10°C used to calculate the nominal reference time.
Reference time at +10°C used to calculate the nominal reference time.

Timer tuning
maximum delay
variation perc.
20 %
Sets the maximum current defrost delay variation percentage. 21.09
Maximum defrosts
per hour 3
Sets the maximum number of defrosts in an hour. If this value is exceeded, the finned coil
alarm appears.
21.10
Ext t.-Evap. t.
calc. interval 300 s
t.ext-t.evap. var.
speed threshold 3.0°C
(only for auto tuning)
Maximum rate of change in the difference between external temperature and evaporation
temperature. If exceeded, it force activates the defrost procedure after the bypass time. The
calculation is updated every "calculation interval"
21.11
21.12
Ext t.-evap. t.
difference threshold
for changing defrost
delay 15.0°C
(only for auto tuning)
Initial threshold for the difference between external temperature and evaporation temperature
for changing the defrost start delay.
21.13
Threshold offset
Start var. 2.0°C
Variation factor
1 %
(only for auto tuning)
Offset used to calculate the threshold for changing the defrost start delay.
Defrost start delay change factor provided by Auto Tuning Defrost.
