19.3 Requirements made of external units
Only units which have been tested according to EN 60950
(=IEC 950) should be connected to the interface of the cir-
culator.
19.4 Setting the desired set value
If the desired set value is set via the computer, this means:
•
If the connection is interrupted, the thermostat conti-
nues to regulate at the last set temperature defined via
the interface.
•
After the mains supply current has been switched off
and on, the circulator controls the temperature to the
last value entered via its keyboard and not the value
given by the computer.
19.5 Correction value
If the desired correction value is set via the computer, this
means:
•
If the interface connection is interrupted, the circulator
operates to the last correction value entered via the
interface.
•
After the mains supply current has been switched off
and on, the circulator operates to the last value entered
via its keyboard and not the value given by the com-
puter.
19.6 Controlling a circulator
The interfaces can be controlled by the user either via a
BASIC program or a higher programming language (under
DOS) or via the Windows-Terminal (under Winwows 3.1x).
