Displayed error codes
After the power supply is switched on, all of dispays will esh on after which the pump will
enter the last running mode before it is switched o. Pressing the main switch button once
changes the mode by the following order:
AUTO, PP1, PP2, PP3, CP1, CP2, CP3, III, II, I
For example, if the pump is operating in CP1 mode, pressing the button once will
cause switching to the next CP2 mode in the list. Entry into a given mode is signaled by
highlighting the appropriate indicator on the panel.
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 eciency to the current system heat
demand. Since the eciency 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 eciency system, it is impossible to reach an optimum oper-
ating 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 eciency curve, see chapter 9 -
(Dependency between pump settings and its operating parameters)
