9.5.1. Control internal / external
The control type can be adjusted in the -OFF- mode only.
Possible parameters:
intern internal temperature control
extern external temperature control with external Pt100 sensor
ext.
Pt100
IMPORTANT:
Additional measures for external temperature control.
Connect a Pt100 sensor to the socket on the rear of the circulator.
Sensor calibration of the external Pt100 sensor is performed in the
>ATCalibration< menu.
Suggested adjustments for external temperature control:
Upper band / Lower band and IntMax / IntMin
see Section >Limits<.
External temperature control does not allow the setpoint to be set via
the “ext. Pt100” socket.
Notice:
Place the external sensor into the temperature-controlled medium and securely fix the
sensor.
