139/CMP
bplpdrf Low pressure bypass time in defrost
Time counted from when 4-way valve switches for defrosting, during which
the low pressure alarm is ignored.
Sec 1
201/CMP
pstartdfr Start defrost count pressure threshold
From when the evaporation pressure falls and remains below this
threshold, the defrost delay timer starts counting down (only when the
compressors are on).
Bar 1
202/CMP
tstartdfr Start defrost temperature threshold
Threshold for the coil temperature that determines the immediate
switching of the 4-way valve for defrosting, if the defrost delay time has
already expired.
°C 1
203/CMP
tstopdfr End defrost temperature
Threshold for the coil temperature above which the defrost ends.
°C 1
204/CMP
tmaxdfr Maximum defrost time
Maximum duration of the defrost phase. After this time the defrost will
always end.
Sec 1
205/CMP
timeindfr Maximum defrost delay
Maximum time limit setting for parameter 215.
Sec 1
206/CMP
ttransient Transient time in defrost
Time required by the compressor to reach stable operating conditions.
Sec 2
207/CMP
deltapdfr Pressure hysteresis to stop count
Evaporation pressure offset relating to the value set for parameter 205,
over which the defrost timer is reset.
Bar 1
208/CMP
maxcnt Maximum count increase
The defrost timer will count down by a variable value according to the rate
of change of the evaporation pressure. This parameter sets the maximum
count down increase value that cannot be exceeded.
num 1
209/CMP
rateomaxp Maximum pressure change rate
Maximum variation envisaged for the evaporation pressure over one
minute.
num 2
210/CMP
tmincntdfr Minimum defrost delay time
Minimum time limit for the calculations performed by the system when
determining the delay between the activation of the timer and the actual
defrost.
