7.1.1 Board Features and Connections
(-)A18AZ/(-)P18AZ outdoor units are equipped with a Universal Outdoor Control (UODC) that interfaces with the
inverter, EcoNet
TM
Control Center, and EcoNet
TM
enabled air-handler or gas furnace using the EcoNet
TM
serial
communication protocol. The UODC provides a low voltage terminal block for control wiring and connections for
various sensors, controls, outdoor fan motor and inverter. If an alert or alarm occurs the EcoNet
TM
Control Center
will display the active faults as well as fault history. If used with the conventional 24 VAC 2-stage thermostat then
these faults can be found using the Bluetooth Contractor's App. Buttons are provided to initiate and terminate
various test modes. A plug-in memory card provides model specific information (model data) necessary for proper
operation.
