Page 51: Limits
HT30-M1 8.6. Limits The limits IntMax and IntMin are only valid under external control (see 7.5. Internal / external control) They restrict the temperature of the internal bath to the desired maximum/minimum, also if the controller would require a higher/lower temperature for the external system. As a result the external setpoint may thus not be reached. -
