Circulation Pump With New Wave 3 Electronics - Immergas VICTRIX EXA 24 X 1 ERP Instruction Booklet And Warning

1.27 CIRCULATION PUMP WITH NEW WAVE 3
ELECTRONICS.
The boiler is supplied with circulator fitted with speed regulator.
These settings are suitable for most systems.
In fact, the pump is equipped with electronic control to set ad-
vanced functions. For proper operation one must select the most
suitable type of operation for the system and select a speed in the
available range, with a focus on energy savings.
By-pass Regulation (Part. 30 Fig. 35). The boiler leaves the fac-
tory with all bypasses 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 and open the
by-pass, anticlockwise it is closed.
Selection of operating mode.
When running, the pump indicates the set configuration by means
of the codified lighting of the LEDs. The setting is changed by a
short pressing of the button.

Constant curve: the circulator operates maintaining constant
speed.
For the "Victrix EXA 24 X 1 ErP" boiler, the pump is set at "Con-
stant curve speed 2" by default.
Real time diagnostics: in the event of malfunction the LEDs
provide information on the circulator operation status, see table
(Fig. 33).

Diagnostics
The circulator pump cannot restart
automatically due to an anomaly
Voltage off range < 160 Vac
The circulator is locked due to
power supply too low or serious
malfunction

automatic release attempts or
manually release the motor shaft
acting on the screw in the centre
of the head.
If the anomaly persists replace the
circulator.
Check power supply.
Check the power supply, if the
