Sequence
1. o61 must be set as the rst parameter. This parameter determines which of the four operating interfaces (application mode) are
activated. This must be set via the display keys. It cannot be set via data communication. (Active functions are shown below in shaded
elds.)
2. Quick- start
To get the system up and running quickly so that cooling can be commenced, start it by setting the following parameters (these pa-
rameters can only be set when the regulation is stopped, r12=0): r23, r28, c08, c16, c29, o06, o30, o75, o76 and nally r12=1.
3. Once the regulation is under way, you can go through the other parameters and adjust them in situ.
