Controlling a chilled water pump based on return temperature.

We need to control a 22kW chilled water pump running on VFD. we need it to start/stop and change its speed based on the reading it is getting from an RTD that measures the return water temperature and converts it to a 4-20 mA signal. we are planning to use Arduino board to control the whole process so we need someone to help us in the programming. We need the Arduino to read the 4-20mA temperature value, then based on some set points we decide later, send a signal to the pump's VFD requesting it to start/ stop/ inc speed/ dec speed etc. The RTD we are using is JUMO dTRANS T03 and the VFD is Schneider Electric ALTIVAR 212 . attached is their datasheets.

Skills: Arduino, Electrical Engineering, Electronics, Microcontroller, PCB Layout
