Zone Circulation Pump - Immergas SUPER TRIO Instructions And Warnings

1.36 ZONE CIRCULATION
PUMP.
The system is supplied with pumps
equipped with speed regulators.
These settings are suitable for most
systems.
Central heating/cooling system
pumps. The circulators are equipped
with electronic control that allows to
set advanced functions. For proper op-
eration one must select the most suita-
ble type of operation for the system and
select a speed in the available range.
The central heating/cooling system
pumps control the room central heat-
ing or cooling requests downstream of
the hydraulic manifold.
- Constant head (ΔP C) (Ref. 4 Fig.
50). The circulator pump maintains
the pressure level (head) constant as
the system heat demand decreases
(flow rate reduction).

working
With these settings, the circulator
pump is suitable for all floor sys-
tems where all the circuits must be
balanced for the same drop in head.
One can select the power level from a
minimum one to a maximum one by
turning the selector switch clockwise
in the relative power scale.
- Proportional head (ΔP V) (Ref. 3
Fig. 50). 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, proving par-
ticularly suitable in single-pipe and
two-pipe installations. Any noise

Adjustment. Turn the selector and
set it on the desired curve to adjust
the pump.
Automatic vent function (Ref. 1 Fig.
50). The circulator pump is equipped
with a function that activates its oper-
ation for 10 minutes, alternating the
speed between minimum and maxi-
mum, so that the air contained in the
circulator pump is expelled by the air
vent valve.
Diagnostics in real time: a light ring
(Ref. 2 Fig. 50) provides, in various
colours, information regarding the
pump operating status, see table below..
Cause
If the circulator pump requires
the automatic vent function often,
one must adjust the operating
mode properly.
a) check power supply
(160 ÷ 253V)
