idF 6 Defrost interval 0 to 120hours
Sets the time interval between the
beginning of two defrost cycles.

[idF = 0]: the defrost can only be
activated manually, or through RS485
or from an external contact or from the
LAN.
MdF 45
(Maximum) defrost
duration
0 to 255min
When dPA is not present, it sets the
defrost duration, otherwise it sets the
maximum duration for defrost.
dSd 0
Defrost start delay
after request
0 to 255min
Useful when different defrost start
times are necessary to avoid
overloading the plant.
dFd it
Display during
defrost
rt; it; SEt; dEF
rt = real temperature for Lod probe

it = initial temperature (reading when
defrost start)

SEt = setpoint value

dEF = “dEF” label is visualized
dAd 30 Display delay 0 to 255min
Set the maximum time between the end
of defrost and the restarting of the real
room temperature display.
Fdt 0
Drain downtime
after defrost
0 to 255min
Time interval between reaching the
defrost termination temperature and the
restoration of the control’s normal
operation. This time allows the
evaporator to eliminate water drops that
might have formed due to defrost. The
fan and the thermoregulation outputs
are OFF during this time.
dPo n
Defrost at power
ON
n; Y
First defrost after startup:
Y = immediately

n = after the idF time
dAF 0.0
Defrost delay after
continuous cycle
0.0 to 24h00min (144)
Time interval between the end of the
fast freezing cycle and the following
defrost related to it.
Format : hours.10min

Resolution : 10min
FAN
FPA P2 Fan probe A
nP(0); P1(1); P2(2);
P3(3); P4(4); P6(5)
First probe used for fan. If [FPA = nP] ,
the regulation is performed with real
value of FPb .
FnC O-n Fan operating mode C-n; C-Y; O-n; O-Y
C-n = running with the solenoid valve,
OFF during the defrost

C-Y = running with the solenoid valve,
ON during the defrost

O-n = continuous mode, OFF during
the defrost

O-Y = continuous mode, ON during the
defrost
