9 Functions CONTROL MODES ecocirc XL and XLplus can be operated with different functional modes. The pump has been factory set at constant pressure without Night Mode. The set point is factory set and it is suitable for more installations. Constant pressure Constant Speed Constant pressure Fixed speed control Speed setpoint The pump maintains a constant pressure at any flow demand. The desired head of the pump can be set via user interface. Constant pressure functional mode is recommended in systems with small or constant pressure losses. The pump maintains a fixed speed at any flow demand. The speed of the pump can be set via user interface. Constant speed is great when used in the primary or boiler loop in a primary/secondary hydronic system. Proportional pressure Proportional pressure Night Mode This function reduces the power consumption of the pump to the minimum when the heating system is not running. An autolearn process detects the proper working conditions. The electronic registers a drop of the water temperature and the circulator automatically decreases the speed. The pump returns to the original set point as soon as the system restarts and the water temperature has increased. The Night Mode can be activated in combination with: The pump pressure is continuously increased / decreased depending on the flow demand. The maximum head can be set via user interface. Proportional pressure functional mode is recommended in systems with relatively large pressure losses in the distribution pipes. Proportional pressure Constant pressure Constant speed It cannot be used in cooling systems. The prerequisite of this functional mode are: The pump has to be installed in the supply line; The night condition can be detected with good confidence if a higher level control system is set to change the supply temperature.

10 Functions CONTROL MODES INFLUENCED BY THE TEMPERATURE ecocirc XLplus version can be used with 3 additional control modes depending on the temperature of the pumped media. The set-up of the control modes as well as of the external temperature sensor, necessary for ΔT control, is available only through Communication BUS or Wireless capabilities by the connection to an external device. ΔP T Control This function changes the nominal differential pressure set point depending on the temperature of the pumped media. The temperature is controlled by the built-in temperature sensor. T Constant temperature control The functional mode changes the speed of the pump in order to maintain a constant temperature of the pumped media. It is suitable for heating systems with fixed system characteristics, for example Domestic Hot Water Systems. The temperature is controlled by the built-in temperature sensor. ΔT Differential temperature control The function changes the speed of the pump in order to maintain a constant differential temperature of the pumped media. This function requires an additional external temperature sensor (type KTY3) that controls, together with the built-in temperature sensor, the differential water temperature in the system. ADDITIONAL OPERATING MODES FOR MULTI-PUMPS SET UP ecocirc XLplus in twin-version version can be used with different operating modes. Back-up operation With this functional model only the master pump runs. The second pump starts in case of failure of the master pump. Alternate operation With this functional mode only one pump runs at the time. The working time is switched every hours so the workload is balanced between both pumps. The second pump is started immediately in case of failure. Parallel operation With this functional mode both pumps run simultaneously at the same set point. The master pump determines the behavior of the full system and is able to optimize the performance. To guarantee the required performance with the minimum power consumption the master pump starts or stops the second pump depending on the head and flow required.

11 Functions READING AND SETTINGS ON THE PUMP Pump settings To change the pump settings it can be used one of the following ways: User Interface Communication BUS (ecocirc XLplus only) Wireless capability (ecocirc XLplus only). Control panel and Display ecocirc XL and ecocirc XLplus features a 3 or digits display with intuitive and user-friendly interface. The control panel has self-explanatory push buttons and is designed to give quick and easy access to the pump and performance data on installation site. Ref. Function Description 1 Control Mode Button Operating modes are cyclically changed by pressing the button Control mode indicators - Constant Pressure - Proportional Pressure - Constant Speed - Night Mode 3 Parameter Button The unit of measurement changes by pressing the button Parameter indicators The units of measuremet displayed are: - Power consumption (W) - Flow rate (m 3 /h - gpm) - Head (m - ft) - Speed (rpm) By pressing the "Parameter Button" for more than 1 second the unit of measurement changes to: - Flow: m 3 /h <--> gpm - Head: m <--> ft Setting Buttons To change the set point: - Press one of the setting buttons: displays starts to blinking the actual set point. - Change the value using the button. - Wait 3 seconds to store and activate the new set point: the display will stop blinking. Digital Display 7 Power indicator When lighted-up power supply is present Status / Fault indicator - Green: pump is working properly - Orange: alarm for system problem - Red: pump failure 9 Remote Control indicator - Off: remote communication deactivated - On: remote communication activated Lowara ecocirc XL and XLplus - Technical catalogue 11

12 Functions COMMUNICATION ecocirc XL and ecocirc XLplus enables communication by the following: External start / stop (Digital input) Signal relay (Digital output) Analog input - V Analog input - ma Communication BUS (ecocirc XLplus only) Wireless capability (ecocirc XLplus only). External start / stop (Digital Input) The pump can be started or stopped via an external potential-free contact or a relay. The pump unit is provided by default with the digital input short-circuited. Signal relay (Digital output) The pump is equipped with a relay for a potential-free fault signal. If there is a fault the relay is activated together with the red status light and the error code on the user interface display. Analog input (-V) The pump integrates a - V analog input. When a voltage input is detected the pump switch to fixed speed control mode automatically and start to work according to the following diagram: Analog input (-ma) Communication BUS ecocirc XLplus can communicate remotely through a built in RS port with the following protocols: Modbus RTU Bacnet MSTP The circulator is factory setting with Modbus protocol. This communication BUS capability offers the possibility to: connect two pumps in dual pumps operation; connect the pump to a BMS (Building Management System); connect the pump to an external device (PC or laptop). It can be used for the following functions: Reading of operating parameters Reading of warning and alarm indications Setting the control mode Setting the set point Setting the control modes influenced by the temperature Give access to all the parameters that cannot be set-up by the user interface. To offer a connection to an external BMS or to a generic external device even when the standard communication BUS is used for dual pump operations (in case of twin-head pumps), the pump can be equipped with an additional communication BUS provided as an optional. Wireless ecocirc XLplus is designed for wireless communication with Smart-Phone or Tablet by an optional Wireless module. The Wireless communication capability offers the possibility to read and set up the pump status. It can be used for the following functions: Reading of operating parameters Reading of warning and alarm indications Setting the control mode Setting the set point Setting the control modes influenced by the temperature Give access to all the parameters that cannot be set-up by the user interface. The pump can be equipped with a -ma external differential pressure sensor with the purpose of increasing the precision in operating modes involved with pressure regulation. 1 Lowara ecocirc XL and XLplus - Technical catalogue
