So I'm looking for some help if anybody knows about arcoair communicating inverter systems. One of our texts diagnosed that it was a bad control board at the air handler and probably a bad thermostat so I changed the control board at the air handler and change the thermostat from The observer to the ion. Now the thermostats finding the indoor unit but not the outdoor and I've checked wiring and I'm still waiting to hear back from tech support. I don't have any books on site and the technical information that we have in the company's storage boxes is not much help so thank you in advance
