5
"PU" vacuum pump
11
Signal line from the "LIS" level sensor of a pressure
maintaining station
6
"PIS" pressure transducer from the device
Magcontrol:
For systems with diaphragm-type pressure expansion tank.
– Using the integrated "PIS" pressure sensor, the system registers and monitors the pressure in the
heating or cooling system. The make-up degassing process is activated as soon as the pressure drops
below the calculated filling pressure.
Levelcontrol:
For systems with pressure maintaining stations.
– The pressure maintaining station uses the "LIS" pressure pick-up to determine the water level in the
expansion tank. The make-up function is triggered by a 230 V signal.
Note!
Ensure the correct connection of the device to the facility system.
– For the Levelcontrol make-up variant in particular, the signal line from the level sensor of the pressure maintaining
station must be connected to the device.
