Compressor Protections (continued)
minimum time the compressor remains turned on
time the compressor remains turned off during the cabinet probe error; also look
at C5
time the compressor remains turned on during the cabinet probe error; also
look at C4
condenser temperature above which the overheated condenser alarm is
activated (only if P4 = 2)
condenser temperature above which the compressor locked alarm is activated
(only if P4 = 2)
compressor locked alarm delay (only if P4 = 2)
compressor 2 delay from power up of compressor 1 (only if u1 = 3)
number of hours of compressor operation above which the LED maintenance
indicator is turned on
0 = no function
defrost
defrost interval (also see d8)
0 = the defrost at intervals will never be activated
kind of defrost

0 = electric defrost

1 = hot gas defrost
defrost termination temperature (only if P3 = 1)
defrost duration if P3 = 0 or 2; maximum defrost duration if P3 = 1
0 = the defrost will never be activated
defrost when you turn on the controller
1 = YES
defrost delay when you turn on the controller (only if d4 = 1); also see i5
temperature shown during the defrost
0 = cabinet temperature
1 = if, upon the activation of defrost, the cabinet temperature is below "working
setpoint + r0", at most "working setpoint + r0"; if, upon the activation of
defrost, the cabinet temperature is above "working setpoint + r0", at most
the current cabinet temperature
drip delay
kind of defrost interval
0 = the defrost will be activated when the controller has remained turned on for
time d0
1 = the defrost will be activated when the compressor has remained turned on
for time d0
2 = the defrost will be activated when the evaporator temperature has
remained below temperature d9 for time d0
evaporator temperature above which the count of the defrost interval is
suspended (only if d8 = 2)
minimum time the compressor must remain turned on before defrost can be
activated (only if d1 = 1)
Temperature Alarms
measured input used for the low temperature alarm
0 = cabinet temperature
1 = evaporator temperature
2 = temperature read by the auxiliary probe (only if P4 = 1 or 2)
temperature below which the low temperature alarm is activated; also look at
A0 and A2
kind of lower temperature alarm
0 = alarm not enabled
1 = relative to the working setpoint (or "working setpoint - A1"; consider A1
without sign)
2 = absolute (or A1)
measured input used for high temperature alarm
0 = cabinet temperature
1 = temperature read by the auxiliary probe (only if P4 = 1 or 2)
temperature above which the high temperature alarm is activated; also look at
A3 and A5
kind of upper temperature alarm
0 = alarm not enabled
1 = relative to the working setpoint (or "working setpoint + A4"; consider A4
without sign)
2 = absolute (or A4)
high temperature alarm delay after turning on the controller (only if A3 = 0 if P4
=1 and A3 = 1)
temperature alarm delay
