5.10 Pump management
The Pump management function can be used for the heating circuit (circulation pump UP1). The
binary outputs BA8 and BA9 should always be used to control the operation of this pump when-
ever a speed-controlled pump is implemented in the heating circuit:
4
BA8 switches the pump on/off
4
BA9 releases the speed control in rated operation or sets the pump to minimum speed oper-
ation during reduced operation
BA8 is closed if the circulation pump is to be switched on. The binary output BA9 can be config-
ured with function block FB28:
4
FB28 = ON: BA9 = OFF outside times-of-use
4
FB28 = OFF: BA9 = ON outside times-of-use
Function WE Configuration

Terminal 12 can be used for the connection of a potentiometer, e.g. to indicate the valve posi-
tion in percent on the controller display or at the control station.
