TECHNICAL NOTE: System minimum water content:

To facilitate proper execution of the AUDAX TOP ErP heat pump defrost cycles, a minimum water content in the system is required,

which must be: 6 l/kW of the machine's power for any type of system. e ywheel guarantees normal operation of AUDAX TOP ErP

with systems divided into zones (with variable water content in circulation). e ywheel also guarantees proper operation with fan coils

used for cooling (a condition in which the ow temperature is very low and has signicant heat load variations that vary the number of

active fan coils). It is also important to check that the dehumidier line has a minimum of 3 l/kW of the machine (dehumidier hydraulic

circuit connection).

N.B.: for inertial tanks codes supplied by Immergas, refer to page 107.

AUDAX TOP 8 ErP range boilers are supplied with a low power

consumption pump with variable speed control.

e circulating pump is equipped with electronic control to set

advanced functions.

Constant head (∆P C) (Ref. 4 above g.) default setting. e

circulator pump maintains the pressure level (head) constant as

the system heat demand decreases (ow rate reduction). With

these settings, the pump is suitable for all oor systems.

Proportional head (∆P V) (Ref. 3 above g.). is allows

the pressure level (head) to be proportionally reduced as the

system heat demand decreases (ow rate reduction). anks to

this function, the electric power consumption of the circulator

pump is reduced further: the energy (power) used by the pump

decreases according to the pressure level and ow rate. With

this setting, the pump guarantees optimal performance in most

heating systems, proving particularly suitable in single-pipe and

two-pipe installations.

All curves have been dened in constant pressure mode with minimum, intermediate and maximum speed.

KEY:

1 - Automatic vent mode operation

2 - Light ring to indicate the operating status

3 - Proportional head operation

4 - Constant head operation

5 - Operating mode selector switch
