Initially it was set to auto. I set it at 5. My humidity in fact (it is cold in NJ) went down and is fluctuating between 25-27% on the hygrometer and 30% on the control panel. I set it to 7. Same. Midday today I switched to manual, keeping it at 7. No change. It is 25 at hygrometer and 29 at the panel.
I see the water going in, I can both hear it and see the water meter rotating.
I also hear the fan.
It is installed on the return.
Come Monday I will call the contractor but it will be warm Monday so I am not sure how they will troubleshoot.
