1.24 CIRCULATION PUMP.
The boilers are supplied with a variable speed
circulator pump. When the boiler is in central
heating mode the circulator speed is defined
by setting parameter “P57” in the configuration
menu (M5), in DHW mode the circulator always
works at the same speed.
During the heating stage the Auto and Fixed
operating modes are available.
•
Auto: automatic pump speed. In this mode one
can choose between the “Proportional head”
and “Constant ∆T” option.
Furthermore, within the parameter it is pos-
sible to adjust the operation range of the
circulator setting limit speed (adjustable from
83 % for model Victrix Zeus Superior 26 2 ErP
and 100 % for model Victrix Zeus Superior 32
2 ErP at 65 %) and minimum speed (adjustable
from 65 % to max. set speed)
- Proportional head ( ∆ T = 0): the circulator
speed varies according to the power emit-
ted by the burner, the greater the power the
greater the speed.
- ∆T Constant (∆T = 5 ÷ 25 K): the pump
speed varies to maintain the ∆T constant
between the system flow and return accord-
ing to set value K.
• Fixed (100 % ÷ 65 %): in this mode the cir-
culator works at constant speed, the operating
range is defined between minimum (65 %) and
maximum (83% for Victrix Zeus Superior 26
2 ErP and 100 % for Victrix Zeus Superior 32
2 ErP).
N.B.:
for the boiler to work properly, it is not
allowed to drop below the minimum value
indicated above.
Possible pump release.
Manually release the mo-
tor shaft by acting on the screw in the centre of
the head, press with a slotted screwdriver in axial
direction and carefully rotate the motor shaft.
By-pass Regulation (part. 32 Fig. 1-29).
The
boiler is supplied with by-pass closed by 1.5 turns
with respect to all open.
If necessary, the by-pass can be regulated to
system requirements from minimum (by-pass
closed) to maximum (by-pass open). Adjust
using a flat head screwdriver, turn clockwise to
close the by-pass; turn anti-clockwise to open it.
Head available to the system.
