1.12 CIRCULATION PUMP ONLY FOR
VERSION AUDAX TOP 1216 ErP.
e pump's interface enables you to select be-
tween 6 pressure levels with 2 types of controls:
• 3 constant pressure/power curve (CP)
• 3 proportional pressure (PP) curves
(*) By pressing the button, the control mode
changes cyclically (CP3 - CP2 - CP1 - PP3 -
PP2 - PP1)
PP1 (fast ashing) LED “I”
PP2 (fast ashing) LED “II”
PP3 (fast ashing) LED “III”
CP1 (slow ashing) LED “I”
CP2 (slow ashing) LED “II”
CP3 (slow ashing) LED “III”
Min ow rate=1; Max ow rate=3
N.B.:
* e variable pressure (PP) mode is recom-
mended for heating systems with radiators.
* e constant pressure (CP) mode is recom-
mended for oor heating systems.
* All hydronic curves have been defined in
constant pressure mode with minimum, in-
termediate and maximum speed.
Setting procedure:
1) Factory setting Constant Pressure Curve CP3
2) Press the button for 10 seconds e pump goes into setting mode - the LED starts ashing
3) Each time it is pressed, the settings change LED “I”, “II”, and “III” are lit / the control curve and mode change (*)
4) 10 seconds aer the button is not pressed e setting is changed - the pump goes back to operating mode
5) LED “I” or “II” or “III” is still lit e pump is operating with the selected mode and curve.
Key:
A - Water ow rate (l/s)
B - Available static pressure (kPa)
