Humidifier is wired up properly to Vision Pro 8K thernostat for operation. Programming was on the wrong setting as the thermostat would turn on the humidifier without turning on the fan. Thermostat is now programmed to properly run fan when running. Worry about mold on humidifier pad is actually iron or rust deposits from bad house water. Geothermal hot water generator is hooked up properly but the shutoff was off. Opened shutoff and burped internal flow pump to be safe. Also test ran in cooling to get hot water generator pump to operate. Pump came on with no issues. Issue with humidifier leaking cancer traced back to high amounts of iron/rust in water. Recommend having the water sofner/filter checked out to ensure proper filtration. Would also recommend replacing waterline to humidifier to prevent the line getting clogged with rust/iron deposits.
