DN - nominal diameter, mm.
Тс - time constant, sec.
L - length along the pipeline axis, mm.
dT - range of temperatures maintained by the controller, °C.
dPmax - maximum pressure drop across the controller, bar.
Xp - proportional band corresponds to the temperature deviation in °C from the setpoint at which the valve of the controller will go to the extreme position.
Kvs - flow coefficient, corresponds to the water flow rate in m³/h at which the pressure drop across the controller will be 1 bar.
