COF2 Compressor2 OFF time with faulty probe2:
(0÷255 min) time during which the compressor is off in case of faulty thermostat probe. With
COF=0 compressor2 is always active.
CH2
Kind of action for section 2
:
CL
= cooling;
Ht
= heating
DISPLAY
CF
Temperature measurement unit:
°C = Celsius; °F = Fahrenheit. When the measurement unit is changed the SET point and the values of
some parameters have to be modified.
rES
Resolution (for °C)
: (in = 1°C; de = 0,1°C) allows decimal point display.
dE
= 0,1°C;
in
= 1 °C
Lod1 Bottom display visualization (section 1):
select which probe is displayed by the instrument in the bottom display:
P1
= Thermostat 1
probe;
P2
= Evaporator 1 probe;
P3
= Thermostat2 probe;
P4
= Evaporator 2 probe
Lod2 Upper display visualization (section 2):
select which probe is displayed by the instrument in the upper display:
P1
= Thermostat 1 probe;
P2
= Evaporator 1 probe;
P3
= Thermostat2 probe;
P4
= Evaporator 2 probe
DEFROST
dFS
Relation between defrosts.
4 relation between the 2 sections of the controller are available, to manage different kinds of applications:
in
=
independent defrosts;
StS
= same defrost start, synchronised defrost end;
St
= same defrost start, independent defrost end;
SE
=
sequential
defrost;
tdF1 Defrost type, section 1: rE
= electrical heater (Compressor OFF);
in
= hot gas (Compressor and defrost relays ON)
EdF1 Defrost mode, section 1: in
=
interval mode
. The defrost starts when the time “
IdF1
” is expired.
Sd
=
Smartdefrost mode
. The time IdF (interval between defrosts) is increased only when the compressor is running (even non
consecutively);
rtc (only for instruments with RTC):
beginning of defrost cycles is set by the
L1d1÷L1d6
parameters during the working days and
S1d1÷S1d6
during the holidays
SdF1 Set point for SMARTDEFROST, section 1
: (-30
÷
30 °C/ -22
÷
86 °F) evaporator temperature which allows the IdF counting (interval between
defrosts) in SMARTDEFROST mode.
dtE1 Defrost termination temperature, section 1:
(-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.
IdF1
Interval between defrosts, section 1:
(1÷120h) Determines the time interval between the beginning of two defrost cycles.
MdF1 (Maximum) duration of defrost, section 1:
(0÷255 min) When
P2P = no
, no evaporator probe, it sets the defrost duration, when
P2P =
yES
, defrost end based on temperature, it sets the maximum length for defrost.
tPF1
Pre-defrost time:
(0÷30min) The compressor is activated for this time before a hot gas defrost.
Fdt1 Drain down time, section 1:
(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.
dPo1 First defrost after start-up, section 1
:
y
= Immediately;
n
= after the IdF time
tdF2 Defrost type, section 2: rE
= electrical heater (Compressor OFF);
in
= hot gas (Compressor and defrost relays ON)
EdF2 Defrost mode, section 2: in
=
interval mode
. The defrost starts when the time “
IdF1
” is expired.
Sd
=
Smartdefrost mode
. The time IdF (interval between defrosts) is increased only when the compressor is running (even non
consecutively);
rtc (only for instruments with RTC):
beginning of defrost cycles is set by the
L1d1÷L1d6
parameters during the working days and
S1d1÷S1d6
during the holidays
SdF2 Set point for SMARTDEFROST, section 2
: (-30
÷
30 °C/ -22
÷
86 °F) evaporator temperature which allows the IdF2 counting (interval
between defrosts) in SMARTDEFROST mode.
dtE2 Defrost termination temperature, section 2:
(-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.
IdF2
Interval between defrosts, section 2:
(1÷120h) Determines the time interval between the beginning of two defrost cycles.
MdF2 (Maximum) duration of defrost, section 2
: (0÷255 min) it sets the defrost duration.
tPF2
Pre-defrost time:
(0÷30min) The compressor 2 is activated for this time before a hot gas defrost.
Fdt2 Drain down time, section 2:
(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.
dFd
Display during defrost
:
rt
= real temperature;
it
= temperature reading at the defrost start;
Set
= set point;
dEF
= “dEF” label;
dEG
= “dEG”
label;
dAd
Defrost display time out:
(0
÷
255 min) Sets the maximum time between the end of defrost and the restarting of the real room temperature
display.
dSd
Start defrost delay
: ( 0÷99min) This is useful when different defrost start times are necessary to avoid overloading the plant.
FANS – Section 1
FnC1 Fan operating mode, section 1
:
C-n
= running with the compressor1, OFF during the defrost;
C-y
= running with the compressor1, ON
during the defrost;
O-n
= continuous mode, OFF during the defrost;
O-y
= continuous mode, ON during the defrost;
Fnd1 Fan delay after defrost, section 1:
(0÷255 min)
The time interval between the defrost end and evaporator 1 fans start.
FSt1
Fan stop temperature, section 1:
(-50÷110°C; -58÷230°F) setting of temperature, detected by evaporator probe, above which the fan is
always OFF.
FAP1 Probe selection for fans management, section 1: nP
= no probe: fan follows the setting of FnC1 parameter;
P1
= thermostat 1 probe;
P2
= evaporator 1probe;
P3
= thermostat 2 probe;
P4
