1、 Function:

1. Opening control, flow control, energy control, temperature difference control, return temperature control, pressure difference control (optional)

2. Flow limitation (2nd generation), temperature difference limitation (2nd generation), opening limitation (to be determined), return temperature limitation (to be determined), energy (to be determined)

2、 Feedback:

Opening degree, instantaneous flow rate, instantaneous energy, supply water temperature, return water temperature, absolute temperature difference, inlet/outlet pressure (optional), pressure difference (optional), cumulative flow rate (2nd generation), cumulative cooling and heating (2nd generation)

3、 Communication:

Modbus-RTU， Bluetooth, Analog (2nd generation), BACnet MS/TP (2nd generation)

Various data feedback:

1、 When the design intent cannot be achieved, the reasons can be analyzed based on data. The flow rate itself is insufficient, or the heat exchange capacity at the end is insufficient.

2、 Assist in optimizing the system, pump valve linkage, etc. There is a margin for product selection, and most of the time the actual load is less than the design load.

Modbus, BACnet communication:

1、 The wiring is simple.

2、 The required parameters can be set through central control.

1. Excessive selection, the flow rate of the valve is greater than the design flow rate.

2. When the actual load is less than the design load or deviates from the design load.

3. Layout changes, new requirements.

4. Inconsistent load in winter and summer.
