SP = Setpoint Programmer
 Press .
The temperature value adjusted and set on the external voltage or
current source is displayed in line 2 of the VFD COMFORT-
DISPLAY for control purposes.
This EPROG input enables the use of different voltage and
current values as program parameters.

UW – Setting the LOW value: : (See below

)
1. Adjust and set the lowest desired value on the voltage or
current source resp. (Example A: 1 V).
Wait appr. 30 seconds.
2. Assign a lower temperature threshold value to this adjusted
voltage/current value by pressing the appropriate buttons on
the keypad of the instrument (Example A: 20
C ) and set by
pressing enter
.
OW – Setting the HIGH value:
(See below

)
1.
Adjust and set the highest desired value on the voltage or
current source resp. (Example A: 10 V).
Wait appr. 30 seconds.
2. Assign an upper temperature threshold value to this
adjusted voltage/current value by pressing the appropriate
buttons on the keypad of the instrument (Example A: 200
C)
and set by pressing enter .

Example out of diagram A:
 Adjusting the voltage source for an output of 7.6 V!
The instrument calculates this value from the rise angle of the two
predecided end points (in example A: 7.6 V correspond to an external
setpoint temperature of 152.0
C ).
After returning the VFD display to standard display by pressing ,
this value is displayed in line 2 (Example: SP 152.00 C).
Notice:
If this adjustment is not correctly performed at two different points, the setpoint setting
will be incorrect.
 Important:
The usable temperature range between > UW < and > OW < is limited to the
configured working temperature range of the circulator resp. of the unit combination
(working temperature range see technical specifications on page 11)
