OK what I want is a specific stage control where my second stage wont come on untill I have an outdoor temp below 20 and both zones all calling at once, preferabley the outdoor temp sensor is adjustable. I have thought about the 4 zone zone first board which is the only zone staging board I have used ( as far as I know honeywell dosent make one) but that board doesnt have an outdoor temp sensor terminal , so I would have to frankinstein in a second board just for that. and before somebody mentions it pro8000 with odts wont work with the zone first board because it only has w2/L on the equip strip, any way this is a 90k job with eff as the only reason we are there so if any body has seen or worked with a designed board that can handle my specs I would appreciate it
