I did call your support line, but they were not much help and told me to return the unit for a new one or they would send me a replacement. I did replace the unit but had the same issue. In the end I did more troubleshooting and found that a had a bad wire. This timer seems more sensitive to resistance over the original timer from a different manufacturer.
A tip for someone that may run into this in the future… This timer seems to have some logic to send power to all zone terminals if it thinks that no zones are connected or has high resistance.
