Features & Benefits
Best-in-class control
Accurate and fast control response even at very low flows in common part load conditions. Ensures full modulating control for the complete operating stroke leading to world class control and efficiencies.
Optional cloud connection
Easy remote access to data and configuration parameters allows to verify and adjust system performance.
High measurement accuracy
High flow and temperature measurement accuracies in all configurations (medium type, and temperature) for all flow regimes.
Compactness and limited number of components
Reduces installation time and space requirements facilitating retrofit installation.
Convenient, reliable setup
Fully customizable and commissionable using Bluetooth enabled smart device reducing commissioning and diagnostic time.
Easy diagnostics
Continuous measurement (flow, temperature, power...) enables accurate error identification in system hydronics.
Versatility in communication
Digital (key Bus protocols and MQTT) and Analog (0(2)-10 VDC or 0(4)-20 mA).
