idF 6 Defrost interval 0 to 120hours
Sets the time interval between the
beginn
ing of two defrost cycles.
[idF = 0]: t
he defrost can only be
activ
ated manually, or through RS485
or from an external contact or from the
LAN.
MdF 45

duration
0 to 255mi
n
When dPA is not present, it sets t

defrost duration, otherwise it sets the
maximum duration for defrost.
dSd 0
Defrost start delay
after request
0 to 255mi
n
Useful when different de
frost start
times are necessary to avoid
overloading the plant.

dAd 30 Display delay 0 to 255min
Set the maximum time between the end
of defrost and the rest
arting of the real
room temperature display.
Fdt 0
Drain downtime
after defrost
0 to 255
min
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.
