C
= constant temperature value
Temperature in °C,
sensor is kept constant at this temperature
ew
= 50°C
F
= Differential control
“
1
” = warmer temperature sensor
T1
“
3
” = colder temperature sensor
T3
ew
= 0
d8.0
= constant kept temperature difference
8.0K between sensors
T1
and
T3
(“F13”)
ew
= 8.0K
L
= Event control (limiting function)
On sensor
T3
operates value “
b
”
On sensor
T1
operates value “
H
”
ew
= 0
“
b
” = limiting temperature
When sensor
T3
increases 60°C sensor
T1
will be kept at tem
perature “H”,
ew
= 60°C
“
h
” = maximum value between 0 to 99°C
“
H
” = maximum value between 100 to 199°C
H30
= Maximum value 130°C for the second
set sensor in position “
L
” (Example: Sensor 1);
sensor
T1
will be kept at 130°C constantly;
ew
= H30 (130°C)

Setting proportional part
F13 = Differential control between T1 and T3. Speed increases,
when temperature difference increases
