PROCEDURE
Go to the “Categories Menu”.
Tap on the category “Temperature Control”.
Tap on the category “TAC/Manual”.
Tap on the sub-category “Configuration manual”.
Tap on the sub-category “control structure”.
Choose between the dialogue entries “Huber PID controller” and “Classic PID controller”.

4.2.10
Sub-category: “Reset parameters”
With this function, you can reset the control parameters to the factory setting.
PROCEDURE
Go to the “Categories Menu”.
Tap on the category “Temperature Control”.
Tap on the category “TAC/Manual”.
Tap on the sub-category “Reset parameters”.
Read the message and confirm it by tapping on “Yes”. The control parameters are reset/deleted.
The temperature control unit can only be operated again after a complete restart.
To do so, switch the temperature control unit off and back on again. The parameters have been
reset.
4.2.11
Sub-category: “Display parameters”
In this function, the set parameters are displayed. Depending on the previous setting, these will be
the “Automatic control parameters” or the “Manual control parameters”.
PROCEDURE
Go to the “Categories Menu”.
Tap on the category “Temperature Control”.
Tap on the category “TAC/Manual”.
Tap on the sub-category “Display parameters”.
Tap on “OK” after you have read/checked the parameters.
4.2.12
Freeze protection for temperature control unit (optional)
Non-compliance with the compatibility between the thermal fluid and your temperature control
unit
MATERIAL DAMAGE
Observe the classification of your temperature control unit according to DIN 12876.
Ensure the following materials are resistant with respect to the thermal fluid: Stainless steel
1.4301 (V2A)/1.4401 (V4A), copper, nickel, HNBR (Unichiller 017 to Unichiller 045), EPDM (from
Unichiller 055), red bronze/brass and silver solder.
The maximum viscosity of the thermal fluid must not exceed 50 mm²/s at the lowest working
temperature!
The maximum density of the thermal fluid may not exceed 1 kg/dm³!
Operation without freeze protection activated
COMPLETE DESTRUCTION OF THE TEMPERATURE CONTROL UNIT
When using water as a thermal fluid, freeze protection must be activated in the category “pro-
tective devices”.
Temperature control units with freeze protection option can use water as the only thermal fluid.
Possible danger: Freezing of the heat exchanger a
t < 5 °C. An ice crystal (green flashing) indicates the
activation of the freeze protection on the touch display. To find out whether your temperature
control unit is equipped with a freeze protection, refer to the datasheet from page 85 in section
.
