1. A method of operating a directly-converting X-ray detector, the directly-converting X-ray detector including a directly-converting sensor material, a conditioning unit, a heating unit and a control device, the directly-converting sensor material being configured to have a DC voltage applied thereto, the conditioning unit being configured to cause a base current to flow through the directly-converting sensor material, the heating unit configured to be regulated by a regulating unit to maintain a working temperature of the directly-converting sensor material, the control device including the regulating unit, and the method being performed when at least one of a new configuration or a reconfiguration process is performed, the method comprises:
maintaining operation of the conditioning unit;
configuring the regulating unit via a serial configuration line, the serial configuration line being connected to a configuration interface of the regulating unit; and
performing a first control operation of the heating unit only during an actual configuration time of the regulating unit, the first control operation including at least one of,
interrupting operation of the heating unit, or
maintaining the operation of the heating unit with a last ascertained control value, the last ascertained control value being a control value most recently ascertained in ordinary operation of the regulating unit.
