After having a new furnace and AC installed in the summer of 2018, replacing my 20-year old equipment, the existing AprilAire 600 whole-house humidifier behaves differently than before.
During the time that the furnace burners are not firing, the humidifier panel is lit, the water runs when it needs to, and the humidity is adequate in moderate weather. When the burners kick on, the humidifier control panel powers off completely and nothing happens until the burners kick off again. Once the burners turn off, the panel powers up, displays an error message (r1) for a few seconds, and resumes operation. This is really only a problem when the weather is really cold because not enough water gets to the panel when the furnace fires more frequently. The furnace is Trane, 2-stage and the AC is American Standard, 1-stage. The AprilAire controller is digital, and the thermostat is Ecobee. Is there a common or likely mistake during install that could cause these symptoms?
