7.12.4 Other defrost parameters
End defrost signal by timeout (par. A3)
Code Description Def Min Max UOM User User terminal
A3 End defrost signal by timeout: 0 = disabled; 1 = enabled 0 0 1 - S NO
Defrost at power on (par. d4)
Code Description Def Min Max UOM User User terminal
d4 Enable defrost at power on: 0 = Disabled 1 = Enabled 0 0 1 - S NO
The defrost request at power on has priority over the control request and activation of the continuous cycle.
Defrost delay at power on (parameter d5)
Code Description Def Min Max UOM User User terminal
d5 Defrost delay at start-up or after command from digital input 0 0 240 min S NO
Also active when d4=0. If the digital input is set to enable or start a defrost from an external contact, parameter d5 represents
the delay between when the defrost is enabled or called, and when it eff ectively starts.
Dripping time after defrost (par. dd)
Code Description Def Min Max UOM User User terminal
dd Dripping time after defrost (0 = no dripping) 2 0 15 min S NO
This parameter is used to stop the compressor and the evaporator fans following a defrost so as to allow the evaporator to drip.
The value of the parameter indicates the off time in minutes. If dd=0 no dripping time is enabled, and at the end of the defrost
control resumes immediately, without stopping the compressor and the fan, if active.
Pump down phase duration (par. cPt)
Code Description Def Min Max UOM User User terminal
cPt Pump down phase duration 0 = pump down disabled 0 0 999 s S NO
The pump down phase is the period in which the evaporator is emptied of liquid refrigerant. Parameter cPt defi nes the duration
of the pump down phase whenever control stops.
Defrost priority over compressor protection (par. d9)
Code Description Def Min Max UOM User User terminal
d9 Defrost priority over compressor protection times:
0 = the compressor protection times are observed;
d9 = 1: the compressor protection times are ignored, therefore defrosting starts without
waiting for the compressor protection times to elapse
0 0 1 - S NO
Parameter d9 can be used to set the defrost priority with respect to compressor protections c1, c2, c3.
Defrost priority over continuous cycle (par. c7)
Code Description Def Min Max UOM User User terminal
c7 Defrost priority over continuous cycle:
0 = continuous cycle has priority; 1 = defrost has priority.
0 0 1 - S NO
Parameter c7 is used to set the priority of defrosting over the continuous cycle:
• if c7 = 0, the continuous cycle has priority over the defrost requests;
• if c7 = 1, if the continuous cycle is in progress and there is a defrost request, the continuous cycle ends and the defrost starts.
Defrost interval unit of measure (par. dC)
Code Description Def Min Max UOM User User terminal
dC Time base for defrosts
0: dI in hours, dP1 and dP2 in minutes; 1: dI in minutes, dP1 and dP2 in seconds
0 0 1 - S NO
Parameter dC is used to change the unit of measure (hours/minutes or minutes/seconds) used to count the times for parameters
dI (defrost interval, hours or minutes), dP1 and dP2 (defrost duration) . This feature is particularly useful when confi guring the
defrosts.
