get thyristor controlled ones- they regulate the output depending on the supply air sensor- bettr than having contactors clunking in and out

Hi install monkey
Thanks for your suggestion. I wish to do that, but there is a requirement that I need to develop a control algorithm for having a step control. I wish to understand the method involved.

Thanks in advance for the help
