ZONE CIRCULATION PUMP.

The appliance is supplied with two circulators both equipped with
speed regulator. These settings are suitable for most plant solutions.
The pump is ideal for the requirements of each central heating
system in a domestic and residential environment. In fact, the
pump is equipped with electronic control that allows to set
advanced functions.
Adjustment
Press the button on the front to adjust the pump. (Ref. 1 Fig. 60).
By rotation, it is possible to select the following pump control
mode:
- Fixed speed I, II, III.
- Proportional head I, II, III.
- Constant head I, II, III.
Fixed speed (Ref. 2 Fig. 50)
Adjusts the pump speed in fixed mode.
It is possible to set 3 different speeds:
- I: Minimum Speed.
- II: Intermediate Speed.
- III: Maximum Speed.
Factory set speed = Fixed speed III
Proportional head (ΔP-V)
This allows the pressure level (head) to be proportionally reduced
as the system heat demand decreases (flow rate reduction).
Thanks 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 flow rate.
With this setting, the pump guarantees optimal performance
in most heating systems, thereby being particularly suitable in
single-pipe and two-pipe installations.
Any noise originating from the water flow in the pipes, valves
and radiators is eliminated by reducing the head.
Optimal conditions for thermal comfort and acoustic well-being.
Constant head (ΔP-C)
The circulator pump maintains the pressure level (head) constant
as the system heat demand decreases (flow rate reduction).
With these settings, the circulator pump is suitable for all floor
systems where all the circuits must be balanced for the same
drop in head.

Other functions:
- The vent function of the pump is activated by pressing and hol-
ding (3 seconds) the control key (Ref. 1 Fig. 60) and automatically
venting the pump.
This function does not act on the central heating / C.H. system.
The pump venting function starts and lasts 10 minutes.
The two sets of upper and lower LEDs (Ref. 5 Fig. 60) flash al-
ternately every 1 second.
To interrupt, press the control key (Ref. 1 Fig. 50) for 3 seconds.
- The manual restart is activated by pressing and holding (5
seconds) the control key (Ref. 1 Fig. 60) and releases the pump
when needed (e.g. after prolonged inactivity periods during the
summer period).
- The keyboard block is activated by pressing and holding (8
seconds) the control key (Ref. 1 Fig. 60) and block the pump
settings. The keyboard block protects against unintentional or
unauthorised pump changes.
Activate the keyboard block by pressing the control key (Ref. 1
Fig. 60) for 8 seconds, until the selected setting LEDs flash (Ref.
5 Fig. 60) briefly and then release.
The LEDs (Ref. 5 Fig. 60) flash continuously 1 second apart.
If the keyboard block is active, the pump settings can no longer
be modified.
The deactivation of the keyboard block takes place in a similar
manner to the activation.
Manual restart
When a blockage is detected, the pump tries to automatically
restart.
If the pump does not automatically restart:
- Activate the manual restart by pressing the control key
(Ref. 1 Fig. 60) for 5 seconds, then release.
- The restart function starts and last max. 10 minutes.
- The LEDs (Ref. 5 Fig. 60) flash one after the other clockwise.
- To interrupt, press the control key (Ref. 1 Fig. 60) for 5 seconds.
