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.
