5.10 Setting the flow rate of the heat transfer liquid
CAUTION!
Bursting of the external application due to overpressure
Scalding, frostbite, impacts

For applications with a maximum permissible working pres-
sure that is less than the maximum pressure of the pump,
use a pressure relief device for protection. This pressure
relief device must be installed in the outflow to the applica-
tion.

Set the maximum pump pressure as per your application.
The pump of the device can be adjusted by means of several pump levels.
This optimizes the flow rate and discharge pressure, noise generation and
mechanical heat input.
If you have connected a pressure-sensitive application and want
to operate without through-flow control, you must use the [Set
pressure] and [Max. pressure] settings in the Pump menu to con-
trol the supply pressure. If through-flow control is active, use the
[Limits] and [Max. pressure] settings for this purpose.
Note that it is not possible to select the pump level when pressure
control or through-flow control is active.

Set pressure for pump

As an alternative to the 8 pump power stages, operation with pres-
sure control is provided. The device then regulates to the set pres-
sure and enables a careful supply of pressure-sensitive consumers.

You enter a value in this entry window when you have connected a
pressure-sensitive consumer. This value in the bar unit depends on
the sensitivity of your consumer. If you enter a set point of 0 bar,
the pressure control is switched off.
n
Outflow pressure

Displays the current pressure at the outlet of the outflow. No
settings can be made here.
n
Max. pressure

Enter the maximum pressure of the connected application. This
must be greater than the set pressure. If the maximum pressure
you entered is exceeded, the device switches off. Pump, heater and
cooling unit are switched off.
