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 at < 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 73 in section
.
PROCEDURE
Go to the “Categories Menu”.
Tap on the category “Protection Options”.
Tap on the category “Freeze Protection”.
Either tap on the dialog entry “off” or “on” to turn the freeze protection on or off.
Confirm your choice by tapping on “OK”.

Setting the setpoint thresholds
The limits for the minimum and maximum setpoints serve for the safety of your system. They should
be set for the application field of the thermal fluid before starting the first temperature control and
when changing the thermal fluid. The maximum setpoint limit limits the setpoint setting for the bath
or flow temperature. The minimum setpoint limit protects against high viscosity or freezing at low
temperatures. Setpoint settings are only available in the temperature range between the minimum
and maximum setpoint limit.
PROCEDURE
Go to the “Categories Menu”.
Tap on the category “Protection Options”.
Tap on the category “Setpoint Limits”.
Tap on the sub-category “Minimum Setpoint”.
Enter the new value, using the numeric keypad that appears.
Confirm your entry by tapping on “OK”.
In the display that follows, confirm your entry again by tapping on “OK”.
The correct selection will be displayed graphically and the “Min. setpoint” will be changed
promptly. If tapping on “OK” is not correct, it will be displayed graphically for 2 seconds. The dis-
play will then return to the category “Setpoint Limits”. Try changing the “Min. Setpoint” again.
Tap on the sub-category “Maximum Setpoint”.
Enter the new value, using the numeric keypad that appears.
Confirm your entry by tapping on “OK”.
In the display that follows, confirm your entry again by tapping on “OK”.
