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.

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