The Camera Unexpectedly Not Recording - SVR trouble condition cannot be manually dismissed. It indicates a recent loss of recording.
To clarify the above regarding thermostat terminals, the ADC T40K has two Z terminals and configuration is specific to either dehumidifier or humidifier. I believe both would operate the same and need voltage on a call, but the call would occur at different times based on the terminal config as either dehumidifier or humidifier.
