1 OPERATING LIMITS Flows up to: m /h* Heads up to: m C Max operating pressure: bars Temperature range: - à + C Max ambient temperature: + C ND of orifices: à * m /h: parallel operation SIRIUX SINGLE AND DOUBLE HIGH EFFICIENCY CIRCULATORS Heating Air-conditioning H m APPLICATIONS SIRIUX SXE For accelerated water circulation for heating or cooling, with optimization of circulator operating point. Central heating, urban heating, commercial or industrial installations; cooling circuits. Air-conditioning systems New, old (renovated) installations or extensions. Circulating pumps recommended for facilities fitted with thermostatically controlled cocks. Qm /hr SIRIUX-- SIRIUX D-- N.T. -/ENG. Éd/-

2 DESIGN Hydraulic part Single or double body with flanges. D internal plotting of the volute casing and impeller for maximum optimization of the hydraulic performances. An impeller seal between the pump body and the impeller improves performances further by limiting the internal recycling of the fluid. The pump body is fully cataphoresis coated to ensure corrosion resistance. Motor V Hz single-phase Wet rotor motor; bearing bushes lubricated by the fluid pumped. E.C.M. (Electronically Commuted Motor) synchronous motor, equipped with a permanent magnet rotor. The stator s rotating magnetic field is generated by the electronic switching of the coils. This rotating field creates a continuous torque through attraction between the rotor s opposite magnetic poles, controlling its position (synchronous motor). This ensures the optimum performance of the motor, whatever its speed. The wet rotor and the windings are separated by a composite, and therefore completely amagnetic, sleeve, to reduce motor losses. SXE with AC motor BENEFITS Energy savings High efficiency circulators, with optimization of the operating point. Energy savings of up to % compared to a traditional circulator. All-purpose These circulators are compatible with all types of heating, air-conditioning and refrigeration systems. The standard version covers a fluid temperature range from C to + C. Noise control Eliminating of whistling and hydraulic noises in the thermostatically controlled cocks. Automatic adapting of speeds to the system s needs. Reliability - Fully automatic operation requiring neither draining nor servicing. A double filter system prevents solid particles from getting into the rotor chamber. A rotating seal between the impeller and the flange limits water exchanges with the motor to the bare minimum. Filter - Circulators shut down via the on/off control start up for a few moments once a day to prevent blocking due to a long period of inactivity. - The electronic modules have a non-volatile memory for data storage. The setpoints are protected in the case of a power cut. - Single or double circulators equipped with IF modules (optional, one IF module per motor) allow many control or remote monitoring functions. Ergonomics Easy electrical connections and adjustments facilitated by direct access via the control module s front panel. The position of the display on the LCD screen may be adjusted according to the position of the control module.

Min: remote operating or curve (through external contact)

4 OPERATING PRINCIPLE The heating or air-conditioning needs of a building vary according to whether it is day or night, but also during the day according to changes in the outside temperature, etc., and even from one point of the building to another as the thermostatically controlled cocks or -way valves are closed. The self-regulated circulator automatically adjusts its rotation speed according to the mains network s loss of load, in order to maintain a minimum electricity consumption (ECM technology) and a low operating noise level. The circulator s properties are adjusted automatically according to the heating or cooling needs of the system. Manual adjustment Parameterization of basic functions, i.e.: - ON/OFF; - control mode, P constant, P variable - and speed adjustment; - automatic adjustment on minimum speed. Constant pressure With this regulation mode, electronic control maintains the constant differential pressure of the circulating pump whatever the flow rate, depending on the predefined pressure instruction. Variable pressure With this regulation mode, the electronic control allows reducing the differential pressure (manometric head) in case of flow reduction, depending on the predefined differential pressure instruction. Speed adjustment The speed may be adjusted manually to a constant value between and rpm. Automatic idling The considerable development of day/night adjustment installations has produced hourly or thermostatically regulated boilers, but not by the adjustment of circulating pumps, which consume energy accelerating cold water circulation. External control (with IF module) This control mode deactivates controlling by the control module. It provides the following functions by means of a - V analogue signal: - remote adjusting of the setpoint P constant remote adjusting of the setpoint P variable - remote adjusting of the speed between the min speed and the max speed - external on-off Double circulators Equipped with two IF (InterFace) units, the Siriux benefits from the following extra functions: Duty/Stand-by The flow requested is provided by a single pump, the other pump starting up in case of fault on first pump or after hours of actual operation of the latter. Cascade operation At minimum load, only the pump in service operates. The backup pump triggers when radiators request a higher flow rate. From this point (switchover point), the nominal speed of the two pumps increases synchronously in case of need. After hours of actual operation, there is built-in (automatic) changeover of the master pump which becomes slave. This function increases energy saving as compared to usual operation in parallel by avoiding numerous locking/ triggering. (See working curves in cascade opposite). Additional functions (IF modules) There are three types of IF module: - IF module Ext. Off - IF module SBM - IF module Ext. Min. with common functions and dedicated function. Modules Ext. Off SBM Ext. Min Functions Double pump management - V analogue input Remote on/off Operation indicator Remote operation Remote monitoring In addition, a dry contact (open by default) allows the remote monitoring of any operating incident (e.g. through a BMS).

5 OPERATING PRINCIPLE CURVE Operation in P constant Operation in P variable Operation in automatic idling H H n H min P constant mode Operation area not used Electronic control maintains constant the differential pressure produced by the pump at the differential pressure value of Hn instruction, up to the curve of operating data through the authorized flow rating. Q H H n / H n H min P variable mode Additional savings compared with constant P mode Electronic control modifies linearly the differential pressure value between Hn and / Hn instruction to be met by the pump. Differential pressure value of H instruction increases or decreases according to the flow. Q Starting temperature (C ) Power input Température départ/heures This device enables making up to % additional saving as compared to operation in P constant. When the heating facility reaches a certain low temperature, the circulator runs on a constant reduced speed until a new rise in temperature.
