I have a Carrier AC/Heat pump system, 2 zone, which uses a Weathermaker Zone Control board. The problem that I am having is that whenever the air turns on heat come out instead of cold air. I even went as far and removed the W1 and W2 wires for the heat pump and the heat still came on. Is the control box bad? If it is where would I find a box for this unit. The closest picture I could find online is for a Zonekit2 box but I cannot find anyone who stocks this part. Is there a compatible board I could use to get my unit running again?

Thanks
