A few months ago I ran into a McQuay SWP with the factory inlet guide vanes. The microtech 1 board was not sending the 12v to the on board relay the closed the contacts to give it 24v to close. It had an old belimo with a potentiometer for feedback to the board. It got quoted to add a drive to it and lock the vanes open
