The controller works automatically at the input with the higher sensor value (E1 or E2).
E.g. for dual circuit condensers in refrigeration technology with two sensors. Automatic control
to sensor which is measuring the higher pressure.

When connecting
passive
temperature sensors type TF.. (KTY81-210) or PT1000 at terminals
“
E1
/ T
”
and/or
“
E2 / T
”
must be paid attention to no polarity.
For a high interference immunity a capacitor must be connected directly to the sensor (1 nF
parallel). With temperature sensors type TF.. (KTY81-210) a capacitor is integrated.
•
When connecting
aktive
sensors at the terminals
“
E1 / GND
”
and/or
“
E2 / GND
”
attention must be
paid to correct polarity, a 24 V DC power supply is integrated.
•
For sensors in two-wire-technology (4 - 20 mA signal), the connection is made on the
“
E1 / 24 V
”
and/or
“
E2 / 24 V
”
,
“
GND
”
terminal is omitted.
