TA-Smart – NPT threads/ANSI flanges
Features and 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.
Optional ΔT and temperature return limitation
Optimize the efficiency of your production units by ensuring optimal temperature regimes.
Change-over functionality
Possibility to switch between two operating conditions to manage seasonality or heating and cooling with the same valve in change-over applications.
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).
Applications
Heating and cooling systems.
