Controller and/or transformer overheating

Live in Phoenix controller is on an exterior wall facing east. Transformer gets very hot and or the unit shuts down. Resetting results in a successful reboot but when a zone or zones are commanded to activate the CPU goes dead. Do I have a mis-wired box or something else.

@teamviper Can you send before/after wiring pictures to They will be able to help troubleshoot if there is a wiring issue or other issue related to the controller.
