TA-Smart (Dp)
IMI
Description
TA-Smart is an inline control valve (through-type) with an EQM control characteristic and an integrated measurement function set for:
-
Flow rate (via ultrasonic flow measurement).
-
Supply/return temperatures (temperature sensors).
-
Calculated thermal power (derived from flow and temperature difference).
It supports two main control modes:
-
Flow control: the actuator modulates the valve to maintain a target flow.
-
Power control: the actuator modulates the valve to maintain a target heating/cooling power using measured flow and ΔTΔT.
Integration detail (DDF):
-
The DDF provides the required input and output signals to integrate TA-Smart into a control system.
-
Limitation: one TA-Smart device is supported per DeviceStation.
