High efficiency pump HEP Optimo L+40-12.0 G250
Description
High efficiency pump with LCD display electronically controlled Armstrong HEP Optimo L+ 40-12.0 G250
Product features
- High-efficiency wet running circulator with integrated automatic modes and additional eco mode for additional savings of approx. 40% compared to the best proportional pressure control.
- Convenient operation with multi-knob and dip switch.
- Optional night mode and locking against unauthorized adjustment.
- Clear display of function, setting and operating status via backlit icons and LCD display.
- Connection possibility of external control (0-10 V, start/stop signal) and omnibus fault indication.
- Numerous integrated additional functions (autom. air ventilation, softstart/inrush current limitation, anti blockage function, electronic motor protection against thermal overload).
- High-quality manufacturing and standard insulation shells.
Use
The wet-running high-efficiency circulators HEP Optimo L+ have an electronically commutated synchronous motor with permanent magnet rotor and a continuously variable differential pressure control. They are designed for use in circulating systems with variable or constant flow.
The inline pump housings are resistant to corrosion by a cathodic electrodeposition coating. The HEP Optimo L+ are designed for a static operating pressure of 10 bar.
Main areas of use
Heating, air conditioning/refrigeration, solar, heat pumps and industrial facilities as
- dual pipe system
- single pipe system
- panel systems like underfloor heating
- boiler and primary circuit
- storage loading circuit
Controls function
With the multi-function button, all settings can be made easily and quickly. The multi-function button consists of an outer dial for the selection of the desired mode and the power set values, and an internal activation pushbutton for the programming start and for the confirmation of the selected mode or the power set point. Lit symbols in the motor cap indicate which mode has been active or selected. By pressing the activation pushbutton for more than 30 seconds, the pump is reset to factory default settings. 10 LED segments located around the outer dial show blue enlightened for the selected power values (10-100% of maximum curve). The display shows alternately head, flow rate and power consumption.
In cases of disturbances the icon SERVICE lights and additional error codes shown on the display enable a rapid troubleshooting. DIP switches located in the Circulator terminal box can be used optionally for locking against unauthorized adjustment and/or for an activation of the night setback
mode.
