5 Operating CCU 100
This chapter describes the operation of the
CCU 100 Combined Control Unit. CCU 100 can be
operated manually or by remote control.
Manual control is done with the keys on the front
panel of CCU 100. Manual operation is described in
Chapter 5.6 Manual Control of CCU 100
Remote control is done with a computer interfaced
to CCU 100 via the serial RS 232 interface and with
suitable software. See
for more infor-
mation.
CCU 100 can only store one target value for tem-
perature and heating/cooling rate at a time. Pro-
gramming temperature profiles into CCU 100 is not
possible on the controller itself. However, the deliv-
ered control software NAMBICON allows to pro-
gram a temperature profile (see the corresponding
software manual that was delivered with the instru-
ment).
