Operating Mode - IBO NOVA 25-40/180 Bedienungsanleitung

OPERATING MODE SELECTION DEPENDING ON THE CENTRAL HEATING INSTALLATION
• Factory settings - AUTO (auto-adaptation mode depending on the central heating system status). Recommended
possible pump settings, depending on the heating system type.
• AUTO/ECO (auto-adaptation) adjusts the pump efficiency to
the current system heat demand. Since the efficiency is
regulated gradually, it is recommended to set the
• AUTO/ECO (auto-adaptation) mode at least a week before
changing the pump settings.
• The pump settings change from the optimum settings to other
optional settings. The heating installation is a low efficiency
system, it is impossible to reach an optimum
operating mode within several minutes or hours. If the optimum
pump settings do not reach ideal heat distribution in each room,
change the pump settings.
• Dependency between the pump settings and the efficiency

PUMP START
Before starting the pump, make sure that the
system is filled with liquid (heating medium), the
system has been properly vented and the
pressure at the pump inlet has reached the
minimum inlet pressure as required
VENTING
Before first start-up and before each heating
season, the pump must be de-aerated. The above
can be carried out by starting the pump in the top
gear 3 and unscrewing the vent plug. If no air
escapes from the resulting hole, and only water
flows out into the hole, screw the cap with the
seal on it.
