,
tEr =
virtual probe for
thermostat;

: 10sec.
rPA
P1
Regulation probe A.
nP(0); P1(1); P2(2);
P3(3); P4(4); P6(5)
First probe used to regulate room temperature. If
[rPA
= nP]
the regulation is performed with real value of
rPb
.
rPb
nP
Regulation probe B.
nP(0); P1(1); P2(2);
P3(3); P4(4); P6(5)
Second probe used to regulate room temperature. If
[rPb = nP]
the regulation is performed with real value
of
rPA
.
rPE
100
Virtual probe percentage (room temperature).
0 to 100%
It defines the percentage of the
rPA
respect to
rPb
.
The value used to regulate room temperature is
obtained by:
value_for_room = (rPA*rPE + rPb*(100-rPE))/100
DEFROST
dPA
P2
Defrost probe A.
nP(0); P1(1); P2(2);
P3(3); P4(4); P6(5)

[rPA = nP]
the regulation
is performed with real value of
dPb
.
dPb
nP
Defrost probe B.
nP(0); P1(1); P2(2);
P3(3); P4(4); P6(5)
Second probe used for defrost. If
[rPB = nP]
the
regulation is performed with real value of
dPA
.
dPE
100
Virtual probe percentage (defrost temperature).
0 to 100%
It defines the percentage of the
dPA
respect to
dPb
.
The value used to regulate room temperature is
obtained by:
value_for_defrost= (dPA*dPE + dPb*(100-dPE))/100

Ld1
,
Ld2
...
parameters;

idF
parameter.
dtP
0.1
Difference between two probes to activate the
defrost.
[0.1°C to 25.5°C]

If the difference between two defrost probes stays
lower than
dtP,
for all
ddP
time, the defrost will be
activated.

Set the temperature measured by the evaporator probe
dPA
which stops the defrost.
N.B.: parameter enabled
only when the evaporator probe is present.
