If the accessory is supplied by IDEAL, please refer to the installation manual
for the connection of the boiler circulation pump.
The circulation pump is controlled by a 230 VAC (1A max.) output on the
NAVISTEM B3000 panel.
This output is active when a request for heat is in progress on the boiler.
If the circulation pump does not have a control switch:
Directly wire the power supply of the circulation pump (230 VAC - 1A
max.) to the terminal QX3 (contacts L3, N and ) on the NAVISTEM
B3000 panel. If the circulation pump consumes more than 1A, the power
supply must be relayed.
If the circulation pump is equipped with a dry-contact On / Off control:
Connect the power supply of the circulation pump directly from your
electric panel.
Use the QX3 output (contacts L3 and N) on the NAVISTEM B3000 panel
(230 VAC - 1 A max.) to wire the circulation pump relay control.
If the circulation pump is equipped with a dry-contact On / Off control:
Connect the power supply of the circulation pump directly from your
electric panel.
Use the UX2 or UX3 output on the NAVISTEM B3000 panel to wire the
circulation pump 0-10V control.
