ELECTRONIC VALVE
By pressing SET you can enter electronic expansion
valve submenu.
FtY

Kind of gas.
R22(0); 134(1); 404(2); 407(3);
410(4); 507(5); CO2(6)
Type of gas used by plant.
Fundamental parameter
for correct functioning of all system
.
SSH
8.0
Superheat set point.
[0.1°C to 25.5°C]
[1°F to 45°F]
This is the value used to regulate superheat.
Pb
6.0
Proportional band.
[0.1°C to 60.0°C]
[1°F to 108°F]
The valve changes its opening on the band
[SSH
,
SSH
+ Pb]
. At
SSH
value of superheat the valve will be at
0% (without integral contribution) and at
[SSH + Pb]
value of superheat the valve will be at
MnF
. For values
bigger than
[SSH + Pb]
the valve is completely
opened.
inC
120
Integration time for superheat regulation.
0 to 255s
-
PEO
50
Valve opening in case of error on probes P5 or P6.
0 to 100%
If a temporary probe error occurs, valve opening
percentage is
PEo
until
PEd
time is elapsed.
OPE
85
Start opening percentage for the time
SFd
.
0 to 100%
Opening valve percentage when start function is active.
This phase duration is
SFd
time.
SFd
1.3
Duration of soft start phase with opening at
OPE
.
0.0 to 42min00sec (252)
Set start function duration and post-defrost duration.
During this phase the alarms are neglected.
Format
: min.10sec,
resolution
: 10 sec.
OPd
100
Post defrost opening percentage for all the time
PddB
.
0 to 100%
Opening valve percentage when after defrost function
is active. This phase duration is
Pdd
time.
Pdd
1.3
Duration of post defrost phase.
0.0 to 42min00sec (252)
Set start function duration and post-defrost duration.
During this phase the alarms are neglected.
Format
: min.10sec,
resolution
: 10 sec.
MnF
100
Maximum percentage of opening admitted (during
normal functioning).
0 to 100%
During regulation it sets the maximum valve opening
percentage.
Fot
nU
Manual opening.
0 to 100%
nU
It permits to force the valve opening to the specified
value. This value overwrites the one calculated by PID
algorithm.
!!!! WARNING !!!!
It must be [Fot = nU] to have correct superheat
regulation.
