SECTION 2
For the
section 2
two defrost modes are available through the “
tdF2
” parameter:
tdF2= rE
defrost with electrical heater
tdF2= in
or hot gas.
The defrost interval is control by means of parameter “
EdF2
”:
rtc (only for instruments with RTC):
beginning of defrost cycles is set by the
L2d1÷L2d6
parameters during the working days and
S2d1÷S2d6
during the holidays
in
the defrost is made every “
IdF
” time
Sd
the interval “IdF” is calculate through Smart Defrost algorithm (only when the compressor is ON)
At the end of defrost the drip time is controlled through the “
Fdt2
” parameter.
3.
RELATION BETWEEN DEFROSTS
Different kinds of defrosts are available for each section.
The relation between defrosts is set by the
dFS
parameter:
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;
•
dFS= in - independent defrosts
The defrosts of the 2 sections of controller are completely independent.
First section:
defrost interval is set by
idF1
parameter.
Second section:
defrost interval is set by
idF2
parameter.
The defrost interval is control by means of parameter “
EdF1(2)
”:
in
the defrost is made every “
IdF1(2)
” time
Sd
the interval “IdF1(2)” is calculate through Smart Defrost algorithm (only when the compressor is ON)
Manual defrost activation, by pushing the DOWN key (defrost 1) or UP key (defrost 2).
By pushing the Down key or Up key for 3s, a defrost request is generated for section 1 or 2 respectively. The defrost interval is re-loaded.
•
dFS = StS – Same defrost start, end defrost synchronised or dFS = St - Same defrost start, end defrost
independent.
The defrost of the 2 sections of controller starts at the same time.
idF1
parameter sets the defrost interval for both the sections. The defrosts are
performed at regular interval if EdF1 = in or according to the Smartdefrost algorithm if EdF1 = Sd.
With
dFS = StS
regulation restarts only when defrost is finished for both the sections. The section that finishes the defrost before the other starts
dripping time until also the other section has not finished its defrost.
Manual defrost activation, by pushing the DOWN key (defrost 1) or UP key (defrost 2).
By pushing the Down key or Up key for 3s, a defrost request is generated for both the sections 1 and 2. The defrost interval is re-loaded.
With
dFS = St
each section restarts regulation as soon as its defrost is finished.
•
dFS = SE – sequential defrost
The defrost of 2 sections is synchronised.
idF1
parameter sets the defrost interval for both the sections. Defrosts are performed at regular interval if
EdF1 = in or according to the Smartdefrost algorithm if EdF1 = Sd. Section 1 does its defrost first, at the end of the defrost of section 1, section 2
starts its defrost..
Manual defrost activation, by pushing the DOWN key (defrost 1) or UP key (defrost 2).
By pushing the Down key or Up key for 3s, a defrost request is generated for both the sections 1 and 2. The defrost interval is re-loaded.
5.
CONTROL OF EVAPORATOR FANS FOR SECTION 1
Section 1 has 1 relay to control evaporator fan (25-26)
The fan control mode is selected by means of the “
FnC1
” parameter:
FnC1=C-n
fans will switch ON and OFF with the compressor and
not run
during defrost
:
;
FnC1= O-n
fans will run continuously, but not during defrost
After defrost, there is a timed fan delay allowing for drip time, set by means of the “Fnd1” parameter.
FnC1=C-y
fans will switch ON and OFF with the compressor and
run
during defrost;
FnC1=O-y
fans will run continuously also during defrost
An additional parameter “
FSt1
” provides the setting of temperature, detected by the evaporator probe, above which the fans are always OFF. This
can be used to make sure circulation of air only if his temperature is lower than set in “FSt1”.
