11.2 Adjusting the correction factors (RTA system)
Display
6
shows the actual temperature at the control sensor.
This temperature does not directly correspond to the temperature in the circula-
tor’s bath, and even less to the temperature in the external connected system.
The temperature difference is determined by measuring the actual current tem-
perature using a suitable measuring device (calibrated or gauged thermometer).
Use the following procedure to enter the correction factor
c
(RTA system) into
the circulator. The factor remains stored in the circulator and is automatically
assigned to the corresponding set point temperature.
Four correction factors can be stored:
cS
,
c1
,
c2
, and
c3
. For example,
c1
is
the correction value associated with
F1
.
The resolution of the correction factor is 0.01°C, and the variation is ± 9.9°C.
Entry
(see the example on the next page):
Switch to the RTA function with the arrow buttons
7
in the menu
FU
. Press
the enter button
8
to confirm this selection.
Press the menu button
3
:
The small display
5
shows
cS
(correction factor for working with the set tem-
perature
S
).
Set the determined temperature difference on display
6
with buttons
7
.
Press the enter button
8
.
This confirms the value as new correction factor
cS
. After the enter button
8
has
been depressed, the correction value remains stored (even in case of a power
failure).
Use the same procedure to adjust the correction factors
c
1 to
c3
for the set
values
F1
to
F3
.
NOTE:
The new value is not saved until the enter button is pressed. The circu-
lator continues to use the old value.
The correction factor “c” may have to be reset if the set point temperature
is changed.
After a short delay, display
6
will automatically return to the actual temperature
display.
