SETTING THE CIRCULATION PUMP
LEDs
The circulation pump (GP13) is equipped
with five LEDs. In normal mode, the
LEDs show the power consumption.
They can also indicate alarms or be used to display the
pump speed.
During normal operation, the LED lights 1 green. The
other LEDs light yellow and indicate the pump's power
consumption according to the following table.
LED indication
Green LED (flashing)
Green + one yellow LED
Green + two yellow LEDs
Green + three yellow LEDs
Green + four yellow LEDs
The speed of the circulation pump (GP13) is set using
the switch (GP13-SF4) so that the projected flow for the
house is achieved. To change the speed, press and hold
the switch until the LEDs start to flash. Scroll between
the various speeds by pressing the switch.
Choose between 10 different speeds on the pump.
There are three different control curves for proportional
pressure (PP), or three different constant pressure (CP)
and four constant curves (CC).
Press the switch once to see what speed is selected.
