SETTING CIRCULATION PUMP
LEDs
The circulation pump (GP1) is equipped with five
LEDs. In normal mode, the LEDs show the
pump's setting by lighting up in green and/or
yellow. The LEDs can also indicate an alarm, in
which case they light up in red and yellow.
The circulation pump's (GP1) various settings are selec-
ted by pressing the switch (GP1-SF4).
Choose between 5 different settings on the circulation
pump.
• proportional pressure auto adapt (PPAA)
• constant pressure auto adapt (CPAA)
• proportional pressure (PP)
• constant pressure (CP)
• constant curve (CC).
The circulation pump's factory setting is CP, speed 3.

Proportional pressure auto adapt (PPAA)
The circulation pump continually regulates the flow
through the system with a great deal of freedom, to
ensure minimum pump power consumption.
The setting is intended for radiator systems. Due to
optimisation to low pumping capacity, the flow may be
insufficient in certain systems.
