If during pump down the status of the low pressure switch changes again and restart during pump down is enabled by setting
parameter c9 = 1, the procedure ends, the compressor restarts and a Restart in pump down alarm Ats is generated. Alarm Ats is

= 0 pump down at start-up is disabled.
7.12 Defrost
Introduction
The iJW controller can manage diff erent types of defrosts, based on the setting of parameter d0. The defrost can end by temper-
ature, in which case the defrost probe Sd must be installed, or by time. At the end of the defrost the dripping phase may begin
(if dd>0), during which the compressor and the fans are off , followed by the post-dripping phase (if Fd>0), during which control
resumes and the fans work based on the setting of parameter Fpd. The type of display on the user terminal during defrosting
can be selected by setting parameter d6.
