If the set temperature value is higher than 100°C the cool-
ing unit will not be switched on. Nevertheless, for special
applications, e.
g.
an expected exothermal reaction, it could
be suitable to let the cooling unit run (only partial cooling
capacity of
30%
of the full capacity).
Select CONTROL, then COOLING and then COOL-HT.
Switch to ON if the cooling unit should run (default set-
ting is OFF).
13.4 Setting the desired set temperature
The settings apply to the internal or external control sensors
according to the selected mode INT-EXT (see chapter
13.2).
Select T-SELECT and then SETPOINT. The currently
valid value is displayed in the
SETPOINT line. The
SET-NEW line indicates the alteration.
Use the arrow keys to select the digit to alter.
Alter the
value between
0 and
9.
Confirm the changes with the ENTER key.
The new value is accepted in the
SETPOINT line.
IDENTflashesfor ashort time after the desired
temper-
ature has been set: The
FuzzyStar-controller is
deter-
mining the right parameter. It can happen that heating
or cooling is interrupted during this process and the dis-
played temperature changes. This is because the con-
trol unit requires some time to determine the parame-
ters.
To switch off the identification please see chapter
15.9.
The input is blocked if a temperature setting over I10 port
already exists or the programmer is active. The message
"110
started" or
"PG
started" will be displayed.
13.5 Setting the
RTA
system correction value
The display shows the actual temperature at the internal
or
external control sensor with the selected resolution.
This temperature does not correspond directly to the tem-
perature in the circulator's bath and even less to the temper-
ature in the external connected system.
The temperature difference
is
determined by measuring the
actual current temperature using a suitable measuring de-
vice (calibrated or gauged thermometer).
