Setting needs to be carried out, if
1. setpoint programming is to be made via an external voltage or
current source or programmer.
For this, in the menu > MENU / CONFIG < first set the menu item
> SETP < to >EPROG<.
2. the heater variable should be controlled via an external control
pulse.
For this, in the menu > MENU / CONFIG < set the menu item
>ACTVAR< to >EPROG<.
3. the signal of an external flow meter should be registered.

1. Connect the external voltage or current source or programmer to
socket (12) REG+E-PROG of the circulator.
2. Selecting the signal:
The programmer (E-PROG) input of the circulator can be matched
to the output signal of the external voltage or current source.
VOLTAGE
voltage input = U
CURRENT
current input =
I
3. Define the input variable:
SETP
Setpoint programmed by external voltage or current
FLOWRAT
Signal of an external flow sensor
ACTVAR Manipulated (ACTuated) variable for the heater
with an external control pulse
4. UW – Setting the LOW value: (See below

)
First adjust and set the lowest voltage or current on the external
voltage or current source (e.g. 0 V or 0 mA).
Then after approx. 30 secs enter the corresponding temperature
value (e.g. 20.00°C).on the circulator by pressing the appropriate
buttons
(
) on the keypad and press enter to set.
5. OW – Setting the HIGH value : (See below

)
First adjust and set the highest voltage or current on the external
voltage or current source (e.g. 10 V or 20 mA).
Then after approx. 30 secs enter the corresponding temperature
value (e.g. 300 °C).on the circulator by pressing the appropriate
buttons (
) on the keypad and press enter to set.
