tdF
Defrost type:
EL = electrical heater;
in = hot gas
2
dtE
Defrost termination temperature: (Enabled only when EdF = Pb).
Sets the temperature measured by the evaporator probe, which causes the
end of defrost.
-50 – 50 °C (-58 – 122 °F)
1
idF
Interval between defrost cycles:
Determines the time interval between the beginning of two defrost cycles.
0 – 120 h
1
MdF
(Maximum) length for defrost:
When P2P = n, (no evaporator probe: timed defrost) it sets the defrost du-
ration,
when P2P = y, (defrost end based on temperature) it sets the maximum
length for defrost.
0 – 255 min
1
dSd
Start defrost delay:
This is useful when different defrost start times are necessary to avoid over-
loading the plant.
0 – 99 min
2
dFd
Temperature displayed during defrost:
rt = real temperature;
it = temperature at defrost start;
SEt = set point;
dEF = “dEF” label
2
dAd
MAX display delay after defrost:
Sets the maximum time between the end of defrost and the restarting of
the real room temperature display.
0 – 255 min
2
Fdt
Drip time: time interval between reaching defrost termination temperature
and the restoring of the control’s normal operation. This time allows the
evaporator to eliminate water drops that might have formed due to de-
frost.
0 – 120 min
1
dPo
First defrost after start-up:
y = immediately;
n = after the IdF time
2
dAF
Defrost delay after continuous cycle: time interval between the end of the
fast freezing cycle and the following defrost related to it.
0 – 23.5 h
