MAGIS HERCULES PRO 12-14-16 is standard equipped with
1 direct circulator pump for zone 1. It is possible to provide an-
other two circulator pumps for mixed zones (zone 2 and zone 3
both optional, can be inserted in the casing) in order to control
a total of three zones (1 direct and 2 mixed).
The system circulator pumps control the room heating or cooling
requests downstream of the hydraulic manifold.
In fact, the circulator pumps are equipped with electronic control
that allows to set advanced functions.
For proper use one must select the most suitable type of oper-
ation for the system.
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
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).
- 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, proving 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.
