Setting the flow rate of the heat transfer liquid

Setting flow rate for Integral T
V6
If necessary, the device carries out the degassing automatically. If the device
detects gas in the hydraulic system, the heating and cooling output is first
reduced or temporarily switched off completely. If the pump pressure drops
sharply (a clear sign of degassing), the pump speed is limited and the pump
may be switched off briefly. When the automatic degassing is finished, the
device resumes its operation automatically.

Protective equipment:
In the Integral T devices, the flow rate is set via the bypass on the right-hand
side of the device. The bypass enables operation with a pressure-sensitive
application.
1. To increase the flow rate and thus the pressure in the consumer, turn
the bypass adjusting wheel clockwise until the desired (< permissible)
pressure for the external consumer is reached.
To display the pump pressure, select the menu items  Pump  Pump
pressure.
The current pressure of the pump in the outflow is displayed. No
settings can be made here.

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.

Before switching on, turn the bypass control knob counterclockwise
to the fully open position.
