The "Magcontrol" operating mode is set in the Customer menu of the device controller. This operating mode is used for facility systems
with a diaphragm-type expansion tank. Water is added according to the pressure in the facility system. The required pressure sensor is
integrated in the device. The degassing lines are connected close to the diaphragm-type expansion tank. This ensures that the pressure
for the make-up with water is monitored.
Note!
Connect the degassing lines at the return side of the system upstream of the hydraulic switching point. The permissible
temperature range of 0 °C
–
70 °C (special types up to 90 °C) can thus be met.
