2 DESIGN Hydraulic part - Double housing with threaded ports for direct fitting onto pipework. M o t o r - Single-phase, glandless, shaft bearings lubricated by the pumped fluid. - Synchronous motor with ECM (Electronically Commuted Motor) technology, equipped with a permanent magnet rotor. The magnetic field rotating around the stator is created by the electronic commutation of the coils. Protection class : IP XD Max. temperature of the conveyed fluid: TF 9 EMC compliance: BENEFITS Energy savings - Conforms to the European Directive: ErP and ErP (Priux home D -). - Energy savings of up to 9% compared to old-generation circulating pumps. - Minimum consumption: watts. - Display of current consumption. Noise control - Elimination of whistling and hydraulic noises thanks to electronic speed variation. Interchangeability - Two sizes of motor: m and 8 m - One type of port-to-port distance: 8 mm. - Type of connection:. Simplified settings - Just one setting dial. -LED display of the manometric head. -Choice of regulation mode according to the installation. Easy replacement - Markings for selecting the manometric head. Installation and maintenance - Requires less space. - Salmson connector: no tools required - Automatic degumming. - Versatility: operation in alternating/backup mode; a control box (not supplied) must be installed for automatic changeover. operation of both pumps in parallel, for savings on purchase and in operation.

3 SETTINGS Setting the Manometric Head Turning the white dial shows the manometric head in m on the LED display. For easier settings, the white dial may be set to the symbols I, II or III on the Δpc scale, which are marker points showing equivalence with the old -speed circulating pumps. Electricity consumption In operating mode, the current power consumption is displayed in W. Factory setting: ½ manometric head - Δpv. Regulation function: With this regulation mode, the differential pressure (manometric head) can be reduced electronically in the event of a reduction in the flow rate, according to the predefined differential pressure setpoint value. Recommended regulation mode for heating systems with thermostatically controlled valves Principle: If the pump is operating in alternating/backup mode, the preselected type of regulation and the manometric head setpoint value must be identical. With this regulation mode, the differential pressure of the circulating pump is kept at a constant level electronically, regardless of the flow rate, according to the predefined pressure setpoint value. Recommended regulation mode for installations with an underfloor heating system and for Thermosiphon-type installations. If both pumps are running in parallel mode at the same time, they MUST be set to Δp-c mode and the manometric head selected must be identical. Venting function: Primary purpose: When first started up, this function allows for the venting of air bubbles contained within the Priux home rotor chamber. Secondary purpose: This function also supports the venting of the heating system. As it operates, air bubbles trapped within the system are released and then conveyed to the highest point of the system (deaerator). The "venting" function lasts for minutes. After these minutes, the manometric head must be reset, otherwise the circulating pump will return to the factory setting.
