
Enter a new setpoint using the number keypad that appears.
The following must apply:
[Minimum setpoint limit] ≤ [Setpoint] ≤ [Maximum setpoint limit].
If these conditions are not met, a message will appear on the >Touchscreen< [88] and the entry
will be ignored. In this case, delete the value just entered either with the “Arrow” key or with the
“clear” key. Enter the setpoint again.

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 setpoint will be changed immediately.
If tapping on “OK” is not correct, this is displayed graphically for 2 seconds. After this, the display
will return to the “Home” screen again. Try changing the setpoint again.

Extremely hot / cold surfaces, connections and thermal fluids
BURNS/FREEZING OF LIMBS
 Surfaces, connections and tempered thermal fluids can be extremely hot or cold depending on
the operating mode.
 Avoid direct contact with surfaces, connections and thermal fluids!
 Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles).
During an active circulation, the thermal fluid circuit is shut off by shut-off valves
MATERIAL DAMAGE TO THE CIRCULATING PUMPS INSTALLED IN THE TEMPERATURE CONTROL
UNIT

Do not close the thermal fluid circuit during an active circulation by means of shut-off valves.

Warm the thermal fluid to room temperature before stopping the circulation.
4.3.1 Externally closed application
4.3.1.1 Filling and venting externally closed application
Non-compliance with the safety data sheet for the thermal fluid to be used
INJURIES
 Risk of injury to the eyes, skin, respiratory tract.
 The safety data sheet for the thermal fluid to be used must be read prior to using it and its
content must be respected.
 Observe the local regulations/work instructions.
 Wear your personal protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).
 Danger of slipping because floor and work area are contaminated. Clean the work station and
follow the instructions for the disposal of thermal fluid and material on page 15 in Section
»Proper disposal of resources and consumables« .
Semi-automatic venting
DAMAGE TO THE TEMPERATURE CONTROL UNIT

An elevated tolerance time for the pressure drop can damage the pump if the thermal fluid
level in the system is also too low.

Constantly observe the thermal fluid level on the >Touchscreen< [88]. Refill thermal fluid as
needed, so that the thermal fluid level does not fall below 20%.
Calculate whether the capacity of the
>Expansion vessel<
[18] can absorb the expansion volume
during operation. Assume the following volumes for this calculation: [Minimum filling capacity of
the temperature control unit] + [Volume of the thermal fluid hoses] + [Jacket volume of your appli-
cation] + [10% / 100 K].
