
Do not move temperature control units that are in operation.
4.1.1 Turning on the temperature control unit
PROCEDURE

Switch on the temperature control unit using the >Mains switch< [37].
Circulation and thermoregulation are turned off.
4.1.2 Turning off the temperature control unit
PROCEDURE

Warm the thermofluid to room temperature.

Stop the thermoregulation.

Switch off the temperature control unit using the >Mains switch< [37].
4.1.3 Setting the overtemperature (OT) protection
The overtemperature protection is set higher than the ignition temperature of the thermal fluid
used
MORTAL DANGER FROM FIRE

The overtemperature protection must be correctly set to the thermal fluid you are using.

Always observe the safety data sheet of the thermal fluid.

Set the cut-out value of the overtemperature protection at least 25 K below the fire point of
the thermal fluid.
4.1.3.1 General information on the overtemperature protection
The overtemperature protection is installed only in temperature control units that have a heater.
The flow temperature is monitored to ensure the safety of your system. It is set immediately after
you have filled the system with thermal fluid.
Upon delivery, the cut- out value of the overtemperature protection is set to 40 °C. An alarm is trig-
gered by the temperature control unit shortly after turning on the power if the temperature of the
thermal fluid just filled is higher than the cut-out value set for the overtemperature protection. Set
the overtemperature protection to the thermal fluid you are using. Please note: The printed scale
can deviate by - 25 K from the set cut-out value.
