d3
Door close duration to switch the compressor back ON again (assuming all
other relevant delays are over)
Min

255
Operation explanation:
•
If door open and Fd = 1
•
Normal operation
•
FAN:
OFF (respecting d4)
•
Door Open indicator:
ON (solid)
•
Defrost Operation
•
FAN:
ON
•
Door Open indicator:
ON (solid)
•
If door remains open for more than d1
•
Normal Operation
•
Compressor:
OFF
•
FAN:
OFF (respecting d4)
•
Main display:
Toggles between regulator probe temperature and “dOP”
•
Door Open indicator:
ON (solid)
•
Defrost Operation
•
FAN:
ON
•
Main display:
Toggles between regulator probe temperature and “dOP”
•
Door Open indicator:
ON (solid)
•
If d1+d2 has elapsed
•
Door Switch is malfunctioning
•
Master Alarm:
ON (solid)
•
Main display:
Toggles between regulator probe temperature, “dOP” and “dSF”
•
Unit resumes working normally (compressor coming ON when there is cooling demand)
•
Unit switches to DAY mode if it was in NIGHT mode when the Door Switch Failure was observed.
•
Unit stops updating the learning matrix and will not switch to NIGHT mode due to learning algorithm, and
once the door switch is restored, then learning matrix will reset.
Door Alarm and Door Malfunctioning RESET:
•
If switch restores proper operation, reset alarm and/or raise “Door Switch Failure Mode”.
•
Controller resumes normal operation
•
Learning matrix will reset

Operation explanation:
•
This parameter defines if ON/OFF – SET button can be used to switch OFF the.
8.10 INITIAL PULL DOWN
Parameter Description
Units
Min
Max
Pdt
Initial pull-down initial temperature
°C
-50
90
Pt1
Time before initial pull-down cut-out (PdO) is activated
Hrs
0
255
PdO
Initial pull-down cut-out value
°C
-50
90
Operation explanation:
•
Initial Pull Down Initiate Temperature (Pdt)
o If regulation probe reading > Pdt for more than Pt1
• Initiate Pull Down respecting PdO (not dnO)
• Do not allow Defrost until PdO is reached, unless dPd is set to YEs
o If dPd= YEs then defrost as regulated by dPt, dPs
• After PdO reached, resume dnO
