I have the option to buy a used Intellitouch I9+3 with Power Center. No actuators or relays. What should I be looking out for what and questions should be asked? I'm considering the Intellitouch due to the ability to control the Intelliflo pumps (VF + VS), which from what I understand, the other manufacturers cannot do.
Any help how to evaluate the Intellitouch so not to get a lemon is appreciated.
