This is what I get in manual : Wiring diagram: And this is physical heater and controller: Can anybody help me out as I am not professional electricial, and could somebody show how to wire heater properly? I will be using 220V AC , as my household does not support 3 phase 400V. I would appreciate any help, but maybe a list of what else do I need, and some diagram how to wire it, as i do not understand fully how do i wire heater to controler and input to heater. Thanks a lot!
