DEFROST
tdF Defrost type:
rE
= electrical heater (Compressor OFF)
rT
= thermostat defrost. During the defrost time “MdF”, the heater switches On and
OFF depending on the evaporator temperature and “dtE” value.
in
= hot gas (Compressor and defrost relays ON)
EdF Defrost mode:
in
=
interval mode
. The defrost starts when the time “
Idf
” is expired.
Sd
=
Smartfrost mode
. The time IdF (interval between defrosts) is increased only
when the compressor is running (even non consecutively) and only if the
evaporator temperature is less than the value in "
SdF
” (set point for
SMARTFROST).
SdF Set point for SMARTFROST
: (-30
30 °C/ -22
86 °F) evaporator temperature
which allows the IdF counting (interval between defrosts) in SMARTFROST mode.
dtE Defrost termination temperature:
(-50,0÷110,0°C; -58÷230°F) (Enabled only when
the evaporator probe is present) sets the temperature measured by the evaporator
probe which causes the end of defrost.
IdF

(1÷120h) Determines the time interval between the
beginning of two defrost cycles.
MdF (Maximum) duration of defrost:

, no evaporator probe,
it sets the defrost duration, when
P2P = y
, defrost end based on temperature, it
sets the maximum length for defrost.

:(0÷59min) This is useful when different defrost start times are
necessary to avoid overloading the plant.
Fdt Drain down time:
(0÷60 min.) 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 defrost.
dPO First defrost after start-up:
y
= Immediately;
n
= after the IdF time
dAF Defrost delay after fast freezing:
(0min÷23h 50min) after a Fast Freezing cycle,
the first defrost will be delayed for this time.
FANS
FnC Fan operating mode:
C-n
= running with the compressor, OFF during the defrost;
C-y
= running with the compressor, ON during the defrost;
O-n
= continuous mode, OFF during the defrost;
O-y
= continuous mode, ON during the defrost;
Fnd Fan delay after defrost:
(0÷255 min)
The time interval between the defrost end
and evaporator fans start.
FSt Fan stop temperature:
(-50÷110°C; -58÷230°F) setting of temperature, detected
by evaporator probe, above which the fan is always OFF.
ALARMS
ALC Temperature alarm configuration
rE

ALU High temperature alarm setting:
ALC= rE, 0
50°C or 90°F
ALC= Ab, ALL
110°C or 230°F
when this temperature is reached and after the ALd delay time the HA alarm is
enabled.
ALL Low temperature alarm setting:
ALC = rE , 0
50 °C or 90°F
ALC = Ab , - 50°C or -58°F
ALU
when this temperature is reached and after the ALd delay time, the LA alarm is
enabled,.
AFH Temperature alarm and fan differential:
(0,1÷25,5°C; 1÷45°F) Intervention
differential for temperature alarm set point and fan regulation set point, always
positive.
ALd Temperature alarm delay:
(0÷255 min) time interval between the detection of an
alarm condition and the corresponding alarm signalling.
dAO Delay of temperature alarm at start-up:
(0min÷23h 50min) time interval between
the detection of the temperature alarm condition after the instrument power on and
the alarm signalling.
EdA Alarm delay at the end of defrost:
(0
255 min) Time interval between the detection
of the temperature alarm condition at the end of defrost and the alarm signalling.
dot Delay of temperature alarm after closing the door :
(0
255 min) Time delay to
signal the temperature alarm condition after closing the door.
doA Open door alarm delay:
(0÷254min,nu) delay between the detection of the open
door condition and its alarm signalling: the flashing message “
dA
” is displayed. If
doA=nu
the door alarm will be not signalled.
nPS Pressure switch number:
(0
15) Number of activation of the pressure switch,
during the “

which the analogue output begins.
APb
Analogue output band width
:
(-50÷110°C or -58°÷230°F) sets the width of the
regulation band for the analogue output. If APb is
positive
then it is above the start
point and the kind of action is direct (condenser application). If APb is
negative
then it
is below the start point and the kind of action is inverse (evaporator application).
