The bypass valve is used to ensure that there is sufficient flow
through the heater in the device to prevent damage to the heat
transfer liquid.
1. If the flow rate in the device is too low, a sound is heard for three
seconds.
The heating switches off on all poles, the pump and the cooling

unit are switched off.
2. In the display the message appears that the flow is too low.
3. Eliminate the cause.
If the reason for the low flow rate is the high flow resistance caused
by the application, turn the adjusting wheel of the bypass valve coun-
terclockwise. Turn the adjusting wheel so far until the required flow is
reached.
4. Press the Enter key.
Also press the Enter key if the device was switched off in the fault
state. Warnings disappear automatically when the cause is eliminated.
