USB-2.0 interface, host
USB-2.0 connection (for connector A), e.g. for data memories.
6.1.2.2
USB-2.0 interface, device
USB-2.0 connection (for Mini-B connector) for communicating with a computer.

DAMAGE TO THE INTERFACES
When devices in operation are connected with interfaces of the temperature control unit,
interfaces may get damaged.
Before connecting, ensure the temperature control unit and the device to be connected are
turned off.

6.2.1.1
Connection jack for Pt100 process controller sensor
A temperature sensor located in the connected application (Pt100, 4-wire technology, Lemosa con-
nector) is connected to the Pt100 connection jack. The external actual temperature is then recorded
and the operating temperature of the temperature control unit is permanently calculated and ad-
justed.
Depending on the operating temperature, isolation losses and exothermic heat, the operating
temperature (flow temperature) of the application can be significantly less than the setpoint of the
application. In this context, safety-critical thresholds for the temperature control fluid must be
strictly observed.
The control results contained in the data sheet can only be achieved with
shielded
sensor leads.
We recommend the external Pt100 process control sensor from the Huber accessories program.
