On power-up, the RTRM looks for a zone temperature input (J6-1, J6-2). If it doesn’t see one, it then ignores zone sensor inputs and looks for thermostat (RGYW) inputs.
However, if the unit does see a valid zone temperature input on startup then the thermostat (RGYW) inputs are ignored. A programmable zone sensor will take priority over either input when connected, and an ICS system takes the highest priority.
