Humidity controller inc-200

Hello, I recently purchased a humidity controller inc-200 for a mushroom Martha tent, at first my mist maker doesn’t have an automatic switch so it doesn’t work on the inkbird (my bad) however I decided to just run the mist maker on low setting and had the inkbird plugged into a fan on work 2, so when the humidity reaches 75-85 % for the first day this was working fine, however last night just after one day now it isn’t turning the fan on unless I plug it into work 1 but then it won’t turn the fan off due to the settings. Does anyone know why this might be? Thank you so much for reading.

Hello,
Please check if the IHC-200 reading is correct?
If correct, please check if the work2 indicator light is on?
