Warning time level
As low-level protection you can enter a warning time until the actual switching off of
the temperature control unit. In case of low-level, a signal will be sent out (you
therefore have to set the signal to
ON
in the main menu point
Acoustic alarm
). Level
indication will be displayed in red. A switch off, however, will take place after the
warning time has elapsed. This function allows you to refill thermal fluid before it
comes to a switch off due to low fluid level.

Sensor adjustment
There exists a possibility to carry out an adjustment of the internal sensor, the process
sensor and the return sensor. We recommend to consult our service department before
carrying out any adjustments of the internal sensor and return sensor (not valid for all
units). An adjustment is only necessary, if due to ageing of sensors measuring is
inaccurate or insufficient. There are different reasons for inaccuracy of the process
sensor, e.g. non-linearity, contact resistance. The new generation thermoregulation
units give you the opportunity to carry out different adjustments. If the inaccuracy
applies over the whole temperature range, adjustment should be carried out only at one
point (offset adjustment). If accuracy is not constant over whole temperature range we
recommend an adjustment of up to 5 spots. The more spots are included the better are
the measuring results afterwards.
For adjustments you will need a reference thermometer with corresponding accuracy.
The sensor of the thermometer has to be positioned as close as possible to the process
sensor.
Settings for the process sensor
Start thermo control and enter a set-point, which serves as first adjustment point.
After set-point is reached, wait until the temperature is constant. Choose the menu
point
Sensor adjustment / Adjust process sensor / New adjustment point
from the
comfort menu. Two sub-menus are available.
Current temperature: Adjustment of the current measured temperature by input of the
reference value.
Other temperature: Input of a previously measured temperature pair.
Service
This menu is only available in service mode, and may only be accessed after contacting
Huber. It allows the unit’s internal sensors and other data to be directly read, for service
purposes.
