TROUBLESHOOTING NOTE: The unit may be operated with an Evolution Connex Control or a standard 2- -stage thermostat. Evolution Connex Systems Communication Failure Control will utilize 5 stages cooling, while 2- -stage thermostat will If communication is lost with the User Interface (UI), the control only allow 2 discrete stages of cooling operation. - Page 15 Temperature Thermistors To use a service tool, connect the A and B communication bus wires from this second communicating control to the terminals Thermistors are electronic devices which sense temperature. As the marked A and B on the terminal strip located in the bottom left temperature increases, the resistance decreases.
