problem you have is your controller is giving 240v ac outputs and your rooftop unit is 24v ac signal so unless you have a bank of transformers down rating the outputs your going to have problems
or alternativly relays in the rooftop unit with 240v ac coils and switching 24v within the unit

Or just use a Carrier approved thermostat then there will be no need to reinvent the wheel.

Correct, i had to put a relays in the machine, becuase the machine control is all 24V. The machines are already working at the moment. Carrier sell this machines anyway, any command or universal thermoestat work with them. My question at the begining was about the command Siemens, but it is very simple work with them...
Sorry the English..
Thanks
