”
(thermal contacts) or thermistors
“

”
(PTC).
The jumper
“
J1
”
in the connection space must be plugged according to the used thermal protectors.
Motor with thermistors
“

”
For motor with thermistors
“

”
the jumper
“

”
must be plugged at the top.
A maximum of six individual thermistors (DIN 44081 or DIN 44082) may be connected in series to
a single device.

Analog input
“
E1
”
for setting fan speed
The device has an analog input for setting the fan speed. Connection

”
/
“
GND
”
(Analog In 1).
The internal jumpers
“
E1.1
”
and
“
E1.2
”
are factory set in the position for a 0...10 V speed setting
signal.
The appropriate jumper positions must be observed for a 0...20 mA signal or a PWM signal.
