CF °F
Temperature
measurement unit
°F(1); °C(0)
°F = Fahrenheit.
°C = Celsius;
CAUTION! When the measurement unit
changes, all para
meters with
temperature values will have to be
checked.
PrU rE Pressure Mode rE(0); Ab(1)
Defines the mode to evaluate the
pressure values
.
CAUTION! Pr
U value is used for all
the
pressure parameters. If [PrU = rE], all
pressure parameters are in relative
pressure unit, if [PrU = Ab], all
pressure parameters are in absolute
pressure unit.
PMU PSI
Pressure
measurement unit
bAr(0); PSI(1); MPA(2)
Selects the pressure measurement units.
MPA means the value of pressure
meas
ured
by kPA*10.
PMd PrE
Pressure probe

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 the 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 perfor
med with the real
value of rPA.
